Computer Doesn't Even Turn On BIOS?
Jan 26, 2012
my mothers laptop (HP-2133 *Large Battery*) just stopped working.There have happened a couple of things, so I'll tell it one by one:- My mother turned on (From hibernation) her laptop one day, and the screen was green.:My thoughts: I thought that it might be the graphics card that had some kind of error on start up, so I just turned it off and on again. Then it ran like it used to. A few hours later the laptop had these random freezes, which made "Force-shutdown" the only possible way of rebooting.:My thoughts: I thought that this was perhaps a virus, but I never got the chance to run our Anti-virus (Kaspersky Antivirus PRO)- Now (two days later), when she/I tries/try to turn on the laptop, nothing happens... The laptop powers on, but doesn't actually run the HDD, or even the motherboard for that matter (Doesn't run the BIOS).
:My thoughts: I noticed that the only light that's on, is the power-light, (The HDD doesn't even blink). I also noticed that the screen doesn't even turn on, but the fans actually run (Most likely because the laptop is powered on)So I can imagine that the motherboard is dead, and in these couple of days, it's shown me that this is it's last days to live.But before I rip it apart and save the value parts, and scrap the rest, I would like to ask you guys for your opinion..

my monitor exhibited signs of flickering during start-up, but only minor ones and would just stop at the 'Welcome' screen of windows so I didn't give it much thought. Iv'e been using it with the cpu the same time I bought the monitor.But after some time, the flickering got worse. It went from 1-2 second interval flickers to a whole 10 seconds of blackness before it showed anything.Now,Iv'e got a new cpu but still using the old monitor. After a day or so, the monitor exhibited the first symptoms of my first cpu, so I just dismissed it. But after a week, It got a hell worse, before I even start-up my computer, the monitor doesn't show Analog/Digital at the top-left corner of the screen. PLUS my cpu keeps restarting after I pushed the ON button after 10 seconds or so. Is the monitor responsible for the restart and what could be the reason for the flickering?

When i got home today didn't my computer work, my girlfriend has been the last one using it. So don't know how things were just before the shutdown or anything.when i turn on the computer i get to the screen where "touch bios" is and where i can see the options like Bios settings, boot menu, xpress recovery.but i cant press anything, and after about two seconds on that screen the PC shuts down again.The keyword lights up so there is a responds on it, but just doesn't work to press anything before it shuts down.I've got BSOD upto several times a day for a few months time.believe that my computer is affected by some virus or something is delaying my computer. might be an combination of several things.I got no external things hugged up to the stationeer computer right now.it is a windows 7 x64 machine.
usually when i get issues i can access advanced boot up or bios, but can neither in this case..I wonder if it might be a hardware issue.

I have a severe virtual problem. Going on in my home and I would like to turn the hyperthreading off in my laptop one is Hp and the other dell. I also have a hp desktop pc with amd... The other 2 have intel...all came with window 7 ....but for the life of me I can't access my hard drive. When I save somehing it saves. It in the ram...how screwed up and my browsers are horrible. The only way I have been able to halfway install a router is thru my screwed up browsers. None of my window 7 pcs seem to know how to configure a router.. I have a new hard drive for Hp desktop. I really hate to install it then I am stuck only accessing the virtual part. I recently installed a new hard drive in my laptop then it went all to hell after I installed seatools. Now I find out the hard drive I bought doesn't need utilities that it automatically installs it self. Too late now . I can't boot or install Windows. Not even linux will install.
I can't afford too lose another $100 on another hard drive. So it is possible to turn off the hyperthreading in the bios ...I just need to know how. I don't play games or watch tv on my pc so I really just need it to be able to email,internet, and music, a printer would be so nice. Its been so long since I have been able to use one. I hook up a printer but everytime samething always happens my pc. States the printer isn't mine and I can't use it. I will settle for the email,music and surfing the net.

Synopsis: PSU died, replaced PSU with different model, system boots to bios successfully but does not recognize any devices in SATA ports, nor do those devices appear to be getting power. Now can't even get to BIOS, entire PC flicks on and off repeatedly as soon as I turn the PSU on regardless of whether I hit the power button on the front of the computer.
System Specifications
Original PSU that died: SeaSonic M12II 750 SS-750AM 750w PSU
CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz
GPUs: ASUS 670 non-top version, SLI (2x)
MOBO: ASRock Z77 extreme 6
RAM: Mushkin Enhanced Blackline 8GB (2 x 4GB) SDRAM DDR3 2133
Optical drive: Sony AD-7280S-0B 24x SATA Internal DVD+/-RW Drive
SSD: SanDisk Extreme 240GB SATA 6.0 Gb-s 2.5-Inch (OS is installed here)
Storage drive: Western Digital Caviar Black 1 TB SATA III (This was not connected when power supply died)
Detailed explanation:About a week ago my PSU (Seasonic 750w) died randomly while the computer was left running in sleep . I RMA'd the dead seasonic. In the mean time I happened to come accross an extremely good deal on a new PSU, so I bought it (Thermaltake smart m850w PSU) to have a backup and to get my machine working again. I hooked up the new PSU to GPUs, CPU, fans, ATX power connector, and to all of the SATA devices, (the SSD, the HDD, and the Optical drive). I made sure to connect the data cables to the SATA devices in the same configuration they were in when working properly. The computer boots successfully to the ASROCK BIOS, all fans spinning. However, I get the error code "A6" on "dr debug" (the led display on the mobo). The manual says this means "SCSI detect". I have no idea what that means.
I was able to load the UEFI, and bios recognized all components except for any of the SATA devices--(SSD, the HDD, and optical drive not recognized). The RAM, GPUs, processor, and fans were detected. At this point I was stuck in BIOS because I couldn't boot off anything.I did not have the HDD connected when the PSU failed, but now the BIOS won't read that either. I don't think any of the SATA devices are actually receiving power. Again, the UEFI showed that there were no SATA devices connected to any port, when in reality they clearly were connected both by power and data cable. Then things get really strange. I unhooked all of the SATA devices except the HDD (the one that wasn't hooked up when the original PSU died). I plug the AC into the PSU, then turn on PSU (not the power switch for the computer, the switch on the PSU). The computer starts flicking on and off in this weird rhythmic pulsating pattern "click...click...click...click..." with about a 1/2 second between each click. Each time the power flicks on, the LEDs come on and the fans spin briefly. The strangest part is that I don't need to hit the power button on the front of the case for this to happen, it just starts as soon as the PSU is turned on. In fact, I can't get the computer to turn on at all--the switch on the front of the computer appears to be dead.
1. Unplug the power cables from everything and re-seated them.
2. Reseated the data cables to the optical drive and the SSD on the drive end, not on the MOBO side as they are covered by my GPUs and I would have to take them out in order to do that.
3. Tried hooking up a SATA power cable from my old modular PSU and using that in the new PSU in an attempt to power the optical drive (didn't work, I know, bad idea--I learned you aren't supposed to do this shortly after I tried it)
4. Setting all preferences to default in the UEFI.
5. Disconnecting the power cables from one or both of the GPUs.
I think that this is either a problem with (1) the motherboard, (2) the new PSU, (3) all 3 SATA devices (unlikely). The fact that I can't even get into Bios anymore tells me that this may be a MOBO or PSU issue.My main question is how to procede from here? I suppose I can wait for my Seasonic to come back from RMA--perhaps that will clear up the issue. I just can't shake the feeling that this is a MOBO issue though. I am worried that if I keep screwing around with it I may end up frying my CPU and GPUs. I can eat the cost of a MOBO or PSU if necessary, but I can't afford to buy a new processor and two new 670s.

Been having shutdown issues for the last several weeks following some issues i was having with an SSD drive and after a few hours of some hard soul serching in safe mode boots, i figured out that its an Nvidia driver that stops the machine from powering down after i hit the shutdown on Windows 7, i've tried reinstalling old drivers as well as the latest ones but i still get the same issue, it shuts down and powers off just fine NO PROBLEM!!! when i uninstall the nvidia drivers, but the second i load them back into windows i get the same problem again, i've been trying to sort this bloody mess out for 2 weeks or more, and finally got it pined to the nvidia drivers.
Spec is : Phenom II X6 1080XT / 8GB DDR3 1333 / 2 EVGA GTX 560 Ti's in SLi mode/ 1TB 7200RPM HDD / ASUS M4N75TD Motherboard / BFG 1000WATT PSU / Using Antec DF-85 case
I've done bios settings and cleared the bios completely, nothing is overclocked, everything is at factory defualts, i've tried updating the bios , and i've also disabled the SLI mode and nothing effected it, and also done several install of windows. One last thing, it shurts down and turns off perfectly fine in safe mode.
The IEE host bus controller in device manager tweak doesn't work, it doesn't matter if the power saving box is checked or not.

I've built an 128gb Samsung (830 Series) SSD into my Acer RL70 Nettop. It was empty and when I tried to boot the nettop there was only the message "ERROR: No boot disk has been detected or the disk has failed". Then I connected the SSD to another computer and installed windows on it and it worked on that PC. When I put it pack into the Nettop i got the same error again. In the Bios, it shows the SSD correctly.

My laptop is an MSI Gx660, running windows 7 64bit with 12gb ram.The laptop is only 1-2months old and My harddisk has very little files with about 205gb free on the C drive.
After using for a long period of time like 6-7hours, I would usually put my laptop into hibernate mode.When I click hibernate, the screen turns black but even after 20mins the power button including wifi and other lights doesnt go off, which I have to force shutdown by holding the power button. Even sleeping the laptop after 6-7hours does the same issue, unable to go to sleep(indicated by the blinking power button)
The wierd thing is that if I use the laptop for about 2 hours or less, I am able to fully hibernate or sleep, which I tested a few times.

I have recently notice that my laptop has the following issues:- Doesn't follow power option settings (shutting off the monitor, go to sleep on timeout, etc)- Doesn't turn on the screen saver. Previewing the screensaver turns it off in about a second (even if my hands are off the mouse/keyboard).- Windows 7 Projector Connection screen (WinKey+P) goes away after a second or so after bringing it up- Some windows open in background (for example, Picasa image viewer opens windowed in the background instead of fullscreen in front as it used to) From what I understand based on some light Googling and vague leads, there is some sort of interrupt happening that makes the OS think it is being actively used. Unfortunately I am not sure how to pinpoint and solve the issue from here on, so therefore I turn to this forum for help. Some notes about stuff I tried and know about this issue:- This must have happened in the past week or two. I do not recall installing any new software and the only updates that passed my memory were Windows Updates.- Checking Task Manager doesn't reveal any suspicious processes to me.- Some sources suggested this could be a faulty Logitech driver. I own a Logitech mouse and keyboard combo.
Something to consider, I guess? Specs:- Windows 7 32b SP 1, up to date- AMD Turion 64 X2 TL-58- 2GB RAM- 250GB HDD- ATI Radeon Xpress 1150- Connected devices: LAN, Logitech Alto Connect Notebook Stand, Logitech S520 Keyboard + mouse that goes with that kit, USB external drive, VGA monitor, line-in running into the microphone port to play sound out of the laptop speakers

The first one is the BIOS boot up screen that usually leads me to Windows. A few months ago, this vanished. I don't know if it was due to a version of Windows 7 i installed or something but whenever I turned on the PC, the screen would appear blank for a few minutes then go straight to the Windows welcome screen. I thought it was weird, but I didn't see a problem since it went to Windows so I disregarded it, which looking back is kind of dumb but I didn't want to risk doing something to the computer in the process.So a few weeks ago I was trying to partition the hard drive so I can install the Windows 8 preview on it, rebooted the computer and...nothing. It wouldn't take me to Windows to there's clearly a problem with the hard drive. I could always get a new one, but there's still the problem of the vanishing BIOS screen.

I forgot my windows password, so I created an Ophcrack ISI Image DVD. When I try this the bios shows my DVD drive in the list of bootable devices, and I select it, save changes, and exit bios, the computer then tries to boot from the hard drive (not the DVD drive selected) and obviously starts up asking for my windows password which I do not have. WHY won't the bios allow me to change the bootable drive to DVD?

I have Windows 7 Ultimate installed on a Dell Optiplex GX620 P4 hyperthread, approx 6 years old. Bios is most current Phoenix ROM Bios Plus 1.10 A11. I have 2 sata drives and 2 IDE drives installed. Boot is from SATA 0. SATA drives 2&3 are not present. All is well with this part of the equation.I had been running a Seagate 250GB IDE drive (ST3250824A) as BIOS drive 4, master drive, jumper selected. I just installed a second 120gb Seagate IDE (ST3120026A) as a slave, BIOS drive 5. That was when things got interesting. When I rebooted BIOS took a long time to load, and then reported that neither IDE drive was present. I then did all the obvious things: Disconnected one drive at a time - BIOS would recognize the connected drive. Switched master & slave drive positions. Changed jumpering from master/slave to cable select. Installed a new ribbon cable. Checked that BIOS drive recognition was set to 'Auto' for both drives. Results are always the same: either drive is recognized when only one is connected but BIOS does not recognize them when both are installed. On boot I receive a warning that IDE Drives 4 & 5 are not present and have to press F1 to continue. When I enter Setup BIOS reports the drives as unknown drive type. When only one is connected BIOS accurately reports the drive model # & capacity.After going through all this,I decided to bring WIn 7 up and see what would happen. To my surprise, Windows 7 showed both drives and worked fine. Device Manager properly reported drive model & capacity. I have used the system in this configuration for several days and everything has worked fine.This is not a problem, per se, since other than slow booting and having to press F1 every time I boot to bypass the BIOS "error" notice the system works fine but I am curious if anyone else has had this problem, and if they found a solution. I have considered forcing a reinstall of the BIOS but since it isn't really broken I don't want to try to fix it and make things worse. I googled this problem before coming here and could not find anyone with an identical situation on any tech site. Can I be the only one who's ever had this happen?

3 year old Sahara Notebook 2gb Ram, Intel Core Duo T2250 Processor. 1.7 GHZ, ATI xpress 200M graphics card. Win 7 Ultimate 32bit Hasn't given me problems for the last few months, until recently.What happened. I was in school studying, shut down the laptop, took a 15 minute walk to my student residence. When I tried to start the laptop. It showed nothing on the screen, not even the BIOS screen. Thought it was a faulty screen, I connected it to another monitor and even a projector. Nothing still showed on them.
When I insert a Win 7 Installation disk in the DVD drive, I can here it humming but still no display. The fan too is working plus the power on and charging lights are working to?

My old monitor has problems turning on, I can leave it on for 30hrs before it decides to display a picture, or I can manipulate it by unplugging the DVI cable from the back, but sometimes even that takes a few tries. It's off warranty and for reference it's a Samsung SyncMaster 226BW.So I bought a new monitor and I have it plugged in using HDMI, but a problem I get is that when both monitors are plugged in the HDMI has no display until it gets to Windows, so I cannot see the boot process of my PC, because my old monitor as explained above has problems turning on. Was a hindrance today when I was tinkering with my SSD and had to go to BIOS, and frankly I'd like to be able to see in case anything goes wrong, like a BSOD or Windows update etc.

trying to install Windows 7 on sony laptop with a copy that is different from the original copy of Windows 7.did partdisk, clean all, create partition, and dvd install gave the "can't install to disk, turn on disk controller in BIOS" error. there is no disk controller function in my BIOS.if partdisk clean all was successful, does that mean the HDD and its controller board are ok, that is, not physically damaged, and the problem is with software/installation/setup etc.?what should i do next, in order to have a successful install?

When I click the "Shut Down" button within windows, the computer will restart and not shut down.
When I physically HOLD DOWN the "Shut Down" button on the computer case, the PC restarts.
I do not have any BSOD's. I do have a memory dump file that say's to be 470,628KB in size but I can't open it.
I have tried disabling my overclock and I have left my overclock on and it DOES NOT make a difference. When I press the "Shut Down" it restarts. When I hold the "Shut Down" button down on my case, it also only restarts.
I would like to add that my motherboard has "Shut Down" button as well and a "Restart" button on the Motherboard, when I hold the "Shut Down" button it also restarts.
I was starting to think about the small 30 Gauge wires that have the super small headers, you know the ones that go to the bottom right of the MOBO, I was thinking perhaps that I got those mixed up in different spots.
But that doesnt logically explain or solve the problem I have from shutting down from within windows, does it?

I had only used it for a day and then the next day it wouldn't even turn on. I have tried everything that I can think of to fix it. From unplugging it and plugging it back in, changing out the power cord with a different one, trying to plug it into a different location in the house, turning the surge protector on and off, etc. I opened the side up and everything seemed to be in place and nothing was obviously unplugged. We do have a warranty but when we called we got put on hold for an hour + and gave up. We will probably call them again Monday I just wondered if there was something else that I should try before calling it quits and switching the computer out completely.

i'm also currently have an issues where, when i switch on the main switch, the computer turn on itself, i didnt even press the power button! And after a few second, maybe 2 to 3 or 4, it turn off itself again. When i press the power button myself, there is no more power. I cant turn it on.So, i do the same thing again. This time I switch off the main switch and turn it back on and the same thing happen again, the computer turn on and off again, and i also cannot switch on the computer after that.The same thing happen the next few time, so i assume there is something wrong with the hardware, or something loose

My xps 410 Dell computer won't turn on. What happens is I turn it on it says to start normally or startup repairs when I click startup repairs it says it can't fix it. When I start normally gets to the multi-colored flag (windows loading screen) and sits there for about 30 seconds to a minute than it either restarts or goes to a black screen and than it has yellow letters surrounded by a small blue rectangle saying "Out of range" I don't know what to do, but what I do know is that I can boot my computer into safe mode which I'm in right now (safe mode with networking)

i have a acer aspire running windows 7 with 500gb hdd and 4 gigs of ram on board graphics card. The computer turns on everything initiates like normal but the monitor wont turn on, im not getting any signal. There are no beep codes etc, also ive tried removing the little lithium battery to reset the bios and still nothing. Ive tried using a different monitor and its saying no signal. I have another computer which is having the same problem its a acer something 1 gig of ram 250 hdd and a readeon graphics card...cant remember the exact name. With this computer i was attempting to add more ram to the extra ram slots and the computer booted up and worked but i only had 2.50 gigs of ram rather than 5? So i turned it off and repositioned theram.which now i wished i hadnt, i now get no signal from either of the computers.
