No Bios Posting And No Screen After Cmos Reset
Feb 6, 2014
i have problem with my computer its 2 months old and now i reseted CMOS from the jumper.
All lights and fans start up but BIOS is not posting and no picture is coming to screen
Specs:
AMD FX-4350
Gigabyte 760gtx OC 4gb
8gb Kingston 1600 MHz
Asus m5a97 2.0
600w LC power psu
I have tried with 1 ram stick and yesterday I ran memtest86 about 16h with no errors so its not ram.
I tried GPU on different slot.
Removed all devices from PC.
Checked that all connections are firmly attached.
Is there possibility that CPU would be dead because I ran prime95
and almost in 1 min I got bsod and I have getting these bsods for almost month (Bsod 0x8000000000000002 on idle)

A while ago I tried to put a new HDD in my laptop and got a message saying something a long the lines that the disk wasn't recognised (forgot exact message)
I took the computer to my computer repair shop and they installed the HDD I asked them if it would be easy for me to do it and they said yes it was just a case of resetting the BIOS.
how to reset the BIOS so I can install a new HDD?
I've installed HDD's in windows 7 machines and it was just a case of inserting the disk- I didn't have to mess with the BIOS!

I have a Dell inspirion 15 laptop running Windows 8.1. A while ago I decided to try Ubuntu out. I installed it alongside Windows 8.1 in dual boot configuration with its own separate hard drive partitions. This means that when I powered on my laptop a GRUB menu (Linux boot manager) would come up allowing me to choose between Windows and Ubuntu. However, Ubuntu was more pain than it was worth so I decided to uninstall it. I did this by deleting the hard drive partitions that Ubuntu was installed on using Windows Disk Management. Now when I power on my laptop the GRUB menu still comes up but there are no options to choose from, only a command line interface. I now have to type Code: exit
which exits GRUB and takes me to my BIOS Boot Manager which looks like this:
Boot mode is set to: UEFI; Secure boot: OFF
UEFI BOOT
ubuntu (ST500LM012 HN-M500MBB)
UEFI Onboard LAN IPv6
UEFI Onboard LAN IPv4
Ubuntu (ST500LM012 HN-M500MBB)
Windows Boot Manager (ST500LM012 HN-M500MBB)
I then have to select Windows Boot Manager to boot into windows.
Why GRUB is still there even though I have deleted the Linux hard drive partitions? Also, why is Ubuntu still listed on the BIOS Boot options? And why is it listed twice?

So lately the system time on my computer wasn't telling the right time, and every time I changed it, it would just change back. So I changed the CMOS battery to what I assumed to be an identical battery, and Windows was unable to start and said I had to system restore. So I took out the old battery and put the new one in and the same thing happened. When it prompts me to restore and I click on it, I just get the black screen with the blue windows icon, minus the loading icon. What should I do?

What does this error mean ?"CMOS checksum error - defaults loaded"
I 've removed the battery on the motherboard and it worked well . , But again there was the same error.
F 1 and F 2 keys do not work.

I have the Thinkpad X230t and normally run Windows 8 x64 with touch just fine. I installed the preview version of Windows 8.1 x64 today. The installation completed quite OK.
At the end of the installation, the installer tries to "set up my account" but then says that it cannot do it at this time, and that I can do it later. I said OK, then log on with my usual Microsoft username and password. Once I'm in the desktop, a message popped up saying Windows cannot find my profile in c:windowssystem32 ... a place like that. This message repeats when I tried to open Desktop, Downloads, or Documents.
I then tried to do a few things in Windows 8.1, but responses were super slow. I then restarted the computer but it froze in the blue restart screen. I then forced a manual restart.
Now I get a black screen right after Bios screen ("Press Enter to interrupt Normal startup"). No flashing cursor, just a plain black screen. None of the keys are responsive, except Ctrl-Alt-Del which will restart the computer, and the same thing happens.
Since I don't have a DVD drive, I cannot boost using the Windows DVD.

I got a 2013 HP laptop Windows 8 and when I attempt to do recovery,restore or even a Img bkup it goes to a black screen with mouse cursor that I'm able to move around but it does nothing else even if I let it sit for hours. I tried to use the built hp software to make a factory recovery disc but it said there was no recovery partition as if it were deleted but in fact a quick look with windows explorer shows it does exists and it perfectly intact plus the disk management shows it intact, healthy and labeled as recovery. As I said before I can reboot into the menu to choose to recover, restore and everything else but once I select one i get the black screen with the mouse arrow. Im trying to avoid buying the discs from hp. Would there be something possibly hiding or blocking the recovery partition ? Maybe a bad registry entry ? I've tried setting folder options to show hidden files and system files.

I have an Acer Aspire laptop which has recently stopped booting up. It doesn't display anything when powered on. I know it is not a problem with windows because it doesn't even display the Bios boot screen. Why is this? The fans start but I cant hear the hard drive.

Trying to address a different problem, Gigabyte suggested that I update the BIOS on my GA-F2A88X-D3H mb from F1 to F3. In addition to not solving the problem, after I updated the image displayed on my monitor--Dell 2209 WA--doesn't fill the screen. Everything's there, but the image stops about 3.5" short of the right bezel.
Using AMD's Catalyst Control Center hasn't worked. I've read some posts about a similar--the same?--issue that suggest changing a setting in "My Flat Panel Display." But I see only "My VGA Display," with no option for over- or under-scanning.
The image does display fully on rebooting--I see the Gigabyte UltraDurable logo, and on entering BIOS instead of going into Windows 8.1 (64-bit).
Since first writing this, I've tried the monitor's menu and other buttons without success.
Is it worth getting a DVI-D to DVI-D cable to connect digitally, in place of the current VGA connection?
Does it signify that the monitor reports a screen resolution exceeding its supposed maximum of 1680 x 1050, namely, 1920 x 1080? In both Windows screen resolution and AMD CCC, I'm unable to set a resolution above 1680 x 1050, and setting lower resolutions doesn't work.

I have a samsung laptop. I turn it on and I can see the bios screen. After that, the screen just goes black and stays that way and doesn't boot. I am able to get into BIOS and I can see all bootable options. I am not able to get into recovery settings or the advanced boot menu.
I burned my Windows 8 iso to my flash drive and plugged it into the computer. I tried automatic repair with it and that didn't fix it. I tried doing a system restore, but it failed saying "System Restore failed while copying the registry from the restore point. The registry in the restore point was damaged and could not be restored." The computer was working during that restore point that. I will try another one though.
It appears that something is corrupt within Windows, but I'm not sure exactly what. I can issue the command in command line, since I can boot to my flash drive, but I'm not sure what files I need to fix or if I'm correct.

I tried updating to Windows 8.1 Update 1 and in didn't go through properly (it hard froze and crashed) and now won't boot past the BIOS. I cannot get into Windows and I cannot get into the Recovery Menu.
I tried recovery USB's and any I create either from a 3rd party or Windows itself results in loading to a black screen with a mouse cursor. Only one worked, Acronis (probably because its Linux) and it showed all the drives ruling out a hardware issue but sadly it cannot repair Windows.
So it seems I might be a victim of the black screen issue some had when moving to Update 1.... BUT the difference is I cannot boot into the recovery menu at all and any recovery media boots to a black screen.
How to get out of this screen and actually boot into anything which will allow me to try to fix the MBR or go back to a restore point.
I thought the point of recovery software was that it loads no matter how corrupted Windows is... obviously not! Something is stopping all of them booting properly.

I just built a desktop with a sabertooth x79 motherboard, and am running Windows 8.1 pro 64-bit. When I click the UEFI BIOS Firmware live tile via the change PC settings>update and recovery>recovery>etc. my computer reboots normally to Windows and will not open BIOS. I have tried accessing it using the delete and f2 keys, but this does nothing either.
I am up to date in terms of my BIOS, and am definitely running UEFI and not legacy.

I'd like a feature in a Bios to enable an ISO on the HDD to be a selectable boot device.
Some MB's have a small Internet Browser built in to the BIOS which can be activated at boot time before loading the OS.
Perhaps even if loading a file system into the BIOS wasn't possible perhaps by selecting this type of option in the BIOS Windows could issue a prompt for the ISO once it could read the file system before loading the rest of its code.

Last night before going to bed my laptop said it was going to update within a day. I closed the lid as usual and the next day, when I opened it, it was stuck on a blank screen for a few minutes then up came the Asus screen, then into Automatic Repair, then Diagnosing your PC, then "Repairing Disk Errors. This might take more than an hour to complete."
I let it run for about 4 hours but with no effect. I tried a few times to no avail. No matter what I do - F8, F10, F12 - I can't do anything other than get into Bios. I fiddled around with some options, but there weren't many and nothing worked. Finally, I removed the hard drive and attached it to another laptop with a caddy and couldn't get in - it is corrupted and unreadable.
So do I simply need a new hard drive? Or is it possible the problem is even worse? A friend says he has a tool that might be able to retrieve some of my files, but at least my most important ones are in Dropbox.
The other concern I have is that even when I install a new hard drive, I don't know how to get an operating system back up. The laptop didn't come with a disk. How do i go about installing an OS? Windows 7 would be preferable, although it did have 8 on it previously.
The laptop is Asus Ultrabook S400C. It doesn't have an internal cd drive.

I have a new Windows 8 laptop and have acquired Windows 8.1 RTM. The install, unlike the Windows 8 install, prompts me for a key. When I installed Windows 8, the installer simply picked up the key stored in the BIOS, as there was no prompt.
Now, however, in 8.1, there is a prompt, and of course I have no way of obtaining the actual key in the BIOS. Is there a way to either force it to pick the key somehow, or is the true way to read the encrypted key in the BIOS so as to enter that at the prompt?

I was installing nvidia gfx card update today when my computer crashed. When I went and restarted it and tried signing in I get preparing windows forever and nothing seems to happen.
So I held shift and pressed restart to get to the troubleshoot/bios menu and then click troubleshoot when I click anything in there such as restart in safe mode or open cmd in order to run a scandisk my computer seems to crash and go to a black screen but the blue light indicating power on my computer stays on.
My OS is installed on a ocz ssd and the only thing I can think of is that my harddrive died.

I have a question about the looks of my BIOS startup screen. I have a relatively new ASUS laptop and i instaled windows 8 on it as soon as possible because ASUS had a free upgrade action.
Everything went well but what i noticed is that when i boot up and the BIOS runs i get in stead of the windows 8 logo with the loading-circle the ASUS logo with the logo circle. Its not annoying or something but i just want the windows logo because i think its nicer.
My friend said it had to do with a BIOS or boot configuration with a ASUS fancy patch switched on.
Ans yes ive already tried replacing my bootres.dll file but it wont give me permission to rename the old bootres file and the new file does not contain the windows logo.

After a thorough search, I didn't find anyway possible to embed a key inside BIOS just like the OEM manufacturers do. The case scenario is quite simple:
Using NoOS(Ubuntu/Dos) laptops that also get marketed with pre-installed Windows 8.X. Purchase bulk OEM, and prepare the laptop to work with exactly the same setup (e.g. UEFI BIOS embedded Windows key) as if it was purchased pre-installed.

On a new Win 8 laptop I can't boot from a USB flash drive or even a CD unless I turn off secure boot in the BIOS?
This surely can't be progress?

So I did a factory reset on my pc, came back into the room to see that my monitor (tv) said no signal and my small LG monitor was black so I just assumed it was part of the process. After about 6 to 7 hours of waiting it still remained the same, even after restarting and trying many other methods to get it to work nothing happens and also it now keeps beeping every 10 to 15 seconds trying to connect my keyboard and mouse, after the beep the mouse and keyboard turn on (the lights on them go on) then after 3 seconds or so they turn off and it does this non stop, also my graphics card is a Radeon 7700 if that has anything to do with it.
