I have a windows 7 os that on bootup gets to the logo then it turns the monitor off so that it says no signal. I can hear the sound of it booting up...no signal. This is a 30 day old build that has been working perfectly. I used the onboard graphics card...same results. Everything works in safe mode(where I'm typing from now)but I cannot access much. I placed this post here because I only had this problem after the latest update(even though I'm not sure they are related). I had already tried to repair/and restore...no affect.
Recently my computer started to show signs that the power supply wasn't working properly. Every time it was unplugged and plugged back to the outlet, a light in the back will blink and make a clicking noise. Two days ago it did it again, when I unplugged it and plugged back in. I unplugged everything from the computer and try turn it on, but it didn't work. I checked all the cables inside and everything seemed to be connected properly. I unplugged the main cable from the motherboard and plugged the power supply and light at the back stopped blinking and remain lit. I decided to plug the motherboard cable. After doing that, the computer started but now it won't boot. All fans are running and there are no clicking or beeping sounds.
I have a Packard Bell Easynote TJ74, i bought it will a defect screen as i was planning to use my tv as the external monitor. For a few months it has worked perfectly. One morning i turned the laptop on and the laptop turned on with certain lights, but did not boot up and the screen which usually just has a white light did not show either, the hard drive lights did not light up but the heat sensitive buttons do work and light up but it's almost like the laptop is on but nothing is happening inside :S. I have the power supply constantly plugged in but the battery is not being used as don't want to over charge. After turning the laptop on and off multiple times it will finally start up correctly and the screen will light up just with a white screen and it will change over to the TV correctly.
my Toshiba laptop screen stays black, my laptop turns on but the screen stays black, I have tried many steps and none has proved, I wonder if it has to do with a cable or is the screen that needs to be replaced.
i am able to turn my computer on for a few seconds but then it automatically shuts itself off after a few seconds but the thing is after letting it sit for a couple seconds it says something about how the clocks on my processor have been overclocked too high and asks if it wants me to restore them, so i do that and then the computer works fine, but then when i turn it off and turn it back on it does the exact same thing until i get that message again.i've tried manually reducing the clocks on my cpu even though they were already at stock clocks and that didnt work
system specs:
windows 7 ultimate 64bit intel core 2 quad q6600 @ 2.4ghz standard clocks 4gb ddr2-800 ram ati hd 4760 1gb ddr3
My system was working fine last week until I've installed an additional SATA HDD, windows will boot up until the windows 7 logo after that its all black screen, I've waited for hours for some response to happen but nothing happened, I've reformatted it a few times with the same outcome. I've tried resetting CMOS a lot of times but to no avail. But this evening I tried taking out my Graphics card and other peripherals and then windows boot! it boots with all other accesories(wifi card,firewire etc.) and the new HDD but when I try to reinstall the Graphics card it goes back to a black screen after the windows 7 logo!! is it a case of a busted video card? if so then why does it have display? I also checked the back of the Graphics card's heatsink and it has this white paste-like goo that has hardened, should i clean it and apply new thermal paste?
I'm contemplating buying a graphic card, but have no clue on which one to get! I'm not really playing games, mostly for my graphic drawing programs. So looking at my specs what would you guys suggest?
I have sent in my computer to get repaired and got it back yestersay. Since then i've been trying to get it to work properly again.I can't play any of the games I used to play before I sent it in to get repaired (for example, Battlefield 3). I can start dota2 but it looks pretty messed up. My computer shows me that I have an nvidia geforce 7025 nforce 630a graphic card.Although it says in the computer description that it SHOULD have a AMD HD 6870 1GB GDDR 5. My screen isn't plugged in the graphic card, since it doesn't recieve anything from there. It is plugged directly to the motherboard.So, from what I understand the nvidia card is the integrated graphic card or am I totally wrong?Anyway, the device manager can only find the nvidia card and I cannot run any game smoothly on this computer.Before I realized this possibility I've tried to download newer drivers for the nvidia card, but it didn't help.
I am aware of the fact that my current gfx cards may be low end for DNF (Radeon 5750x2) but what is happening is that the game shuts down the monitor ingame. Like shutting down the signal (?). This occurs anytime from 5 minutes in to the game up to 30 minutes or so. Only solution to get signal back is a hard reset.I have set up a GPU monitoring software (AMD Overdrive) to measure temps and will post logs here later, my intention with this post is to figure out any other verification measure I might take to verify that this is indeed this game overloading gfx cards?
I run build 6956 and I am impressed with new Windows. Just one problem but big (also was on 6801 build) screen on mine hp 8510p notebook never goes dim or switch off, even when I define those times in >Display...
My first guess was that since we have an electrical instability in our home, perhaps the uneven flows of power would sometimes send a false signal to the power unit of the computer and trigger a start-up (quite often the lights in our home will briefly, and sometimes violently, wave up and down, especially at night).
When I turn my PC off, it turns on by himself. Only when I remove cable from electricity I can solve this problem. This problem started to show up after I changed video card. What reason could it be for this problem and how can I solve it?
I recently changed my PC's power supply, but when I arrived home and turned it on, it turned off by itself a few minutes after booting the OS.Now every time I turn it on, after a few minutes it powers down again while booting.
so basically most nights when i go to bed i will put my computer on sleep, but recently my computer has been turning itself on during the night, i checked task scheduler and there is nothing there that would trigger this, although i tried the powercfg lastwake command in command prompt and got this
i just got my pc on july 24 and never had many problems with it but now it shuts off and turns back on. please help because i don't know what to do and im in school.
i am facing a unique problem. I recently installed windows 7 ultimate 64 bit on my pc. the pc runs normally for about 30 to 45 mins. but later monitor turns off with a "no signal" indication. but when i check, the processor is still running. then to get the signal back again, i must restart my system. then after boot up, i get the message saying windows was not shut down properly. i am not able to understand what is creating the problem. is the problem with hardware. or with windows 7. i never faced such kind of problem before when i was using windows xp SP3.
Motherboard: MSI Z68A-G45 Nvidia GTX 580 (Latest 285.62 Drivers) Windows 7 64 Bit
I've had this computer about 2 months and everything was working great until today. This problem started out of nowhere. I didn't mess around with drivers etc.
Anyway, when I switch on my computer, the bios screen loads up..followed by the Windows 7 loading splash screen. Then just when the welcome screen should appear, my monitor turns to standby and says that it's not receiving an input signal.
I booted in safe mode and removed the drivers. I restarted my PC and it worked and my desktop appeared. However when i install the drivers again and restart the computer as required by the driver installation..the same problem as above reappears.
My monitor is connected via a HDMI cable to the GTX 580.
EDIT: When I go to device manager and right click the GTX 580..there is an option to roll back drivers. I clicked this and it now shows as a VGA Adapter. I restarted and my computer booted up...but obviously in low resolution as no previous drivers were ever installed since i bought the PC with up to date drivers.
I also just installed 290.53 BETA drivers. Restarted and my computer now just hangs at the welcome screen. I can still boot in safe mode which is how i'm managing to write this.
i hav this friend of mine whose computer turns off itself few seconds later after turning it on,it has been running perfectly before this,until he installed another 1GB DDR2 ram..i cant figure out what the problem is.
I installed Windows 7 on my own and started installing drivers. At first, I downloaded and installed drivers for ASUS x54h laptop, not x54hy because it says ASUS X54H on the sticker on the laptop.
I figured it out I was installing the wrong drivers so I installed new ones. Everything was fine, until for the last few days.
I turn on the laptop and everything is fine until the desktop shows and then my screen turns off. It's completely black. I have to restart my computer (sometimes few times) in order to work. I tried reinstalling the drivers. I completely deleted them with DriverSweeper and installed them again. I tried repairing the Windows, but the problem is still here.
I'd like to solve the problem without reinstalling the Windows (but I will do that if it's necessary). I googled the problem many times without finding anything useful.
Since about 1 month my PC turns randomly off. Sometimes after 10 hours, sometimes after 2. Mostly when in Idle or when I'm watching movies on a second Monitor (TV but it also crashes if it is unplugged so thats not the reason). Sometimes when I try to boot again it wont start except if I turn off the PSU for ~15 seconds. Sometimes when I reboot there's an error message "Asus Anti Surge was triggered".
I already tried: - Replaced my OCZ ModXstream 600w with a Corsair AX750 PSU - Stock settings in Bios - Asus Anti surge deactivated - Changed the power outlet to another one
My hardware: i5 3570k @4,3 GHZ Asus Sabertooth Z77 GeiL Evo Corsa 16GB Sapphire AMD 6970HD 2 Harddisks 250/500gb 1 SSD OCZ Agility 3 120gb
And like I mentioned 2 different PSU's. OCZ ModXstream 600w Corsair AX750
I performed a new 32-bit install of Windows 7. For some reason, the monitor shuts off when windows starts. I found that after Windows boots, if I hit the "sleep" button on my keyboard, allow the computer to sleep, then wake the computer, the monitor turns on and everything is fine. Why would they force a person to put the PC into sleep mode every time the PC is booted? I have a PC with a Gigabyte GA-MA69G-S3H motherboard (AMD 690G chipset). I'm using the integrated graphics and I removed everything from the PC except for the drives, monitor, and mouse.
My Laptop screen turns off when I close the lid also I have edited the power options and the plan settings and I choosed to never turn off the display?
i have installed 2 case fans to have to air flow. and when i booted the pc couple of mins later, it suddenly turns off. i unplug both of the case fans and did the same thing.
My graphics is a GTX 460. I built a new computer on the 10th of january and up until tuesday the 17th everything has been running perfectly. But on tuesday my graphics card driver would continuously crash and then recover.Now my graphics card has started to turn off completely, and the computer would reboot. This mostly happens while playing a game. But it also happens while browing the internet too.I've my graphics card in my old computer right now, and everything seems to be running fine.
Sometimes when I power-up my pc everything goes on (fans, HDDs, MOBO..) 2-3 sec later it shuts (won't even get to the bios boot screen) then few seconds later it will turn itself on and stay on (log into windows..)
every morning when I turn my PC on it turns itself off after about 5 seconds. Once it's off, pressing the on button does nothing. I have to flick the PSU switch at the back off and on again for the front button to turn the computer on again. It'll then turn itself off again after a few seconds and I have to repeat the process. Eventually it decides to stay on and it boots up fine.
I'm worried that one day it just won't turn on at all. One thing that might be worth mentioning is that if we've had a powercut in the house at all, even when my computer is switched off, when power resumes and I turn my computer back on, it tells me there's a CMOS checksum error and my BIOS settings are restored to default, as well as the time in Windows being set to 2003. How can this happen when my computer wasn't even on at the time of the powercut?
I just put my new PC together today. I installed Windows 7 ok, went to restart, and about 10 seconds after the Windows logo comes up, it all turns off.
Not sure if this is a WMC/Windows 7 issue or a TV issue.
I have an HTPC hooked up to a TV via an HDMI matrix. When I run the screensave (photo gallery) on my WMC I lose the signal to the TV very 20-25 minutes. I know this as I get a "No Signal" message. When I click on the keyboard the signal resets. This does not occur if I am watching a movie in WMC. Only when the screen save is running.
I don't seem to get this when I run the screen saver (photo gallery) on Apple TV through the same TV. It plays indefinately.
Is there a setting in WMC that turns off the screen saver slide show? Or is this a problem with my TV/Signal?
