Windows 7: BSOD with 0xb4

BSOD with 0xb4

Hi guys. Using a desktop with Windows 7 Professional 4gb ram. Had no problems until today when I tried to switch it on and it took a really long time to get to the Windows Starting screen, and then it checked the disks for consistency. When it restarted, it went to this BSOD with the message, " The video driver failed to initialize".

Then it went to Startup repair, which couldnt repair the problem. And then I decided to use the onboard graphics instead of the gfx card, and I could boot into Windows! However, I did the mistake of going to device manager, where they said there was some problem with the adapter, and click to restart the computer, which I did, and I havent been able to boot back into Windows since, with the same error message coming up.

I've tried booting into safe mode and all, and it doesn't work,so I'm not sure how to collect the dump messages. Is there any way to solve this without doing a clean install? I was thinking I could transfer some important files to another place using a hard disk enclosure, and then clean install, but thats a last resort. Also, is it a sign my hard disk could be failing? Really hope you guys can help. Thanks!

Welcome!

Rarely do BSOD problems come to a clean install, so we will do our best.

Please upload your dmp files found in C:\Windows\Minidump.

You may have to pull the hard drive to another machine, add it as a secondary drive, and upload the dumps.

Try removing the video card. Perhaps that is the problem.

Well we can try other troubleshooting steps without the dmps. If you want a 3.5" enclosure anyway, this is your excuse to buy it, but I hate to recommend purchases unless it is clear they are necessary.

For now, try removing your video card. Be sure that your onboard graphics are set as Primary in the BIOS BEFORE removing the card.

I did what you suggested. Removed the video card, and I was able to log on to Windows! Some errors popped up, to do with the hptray stuff etc. Not sure whether my printer software could be causing problems? In device manager, the graphics adapter says you gotta restart the computer before changes can be applied, because the drivers were installed by Windows when I logged on. Should I not do that?

The zip file is attached. Please help. I'm not sure whether my gfx card is dead, or its simply the driver thats having the problem. Thank you very much.

Just great. I had to shut down my computer, and when I switched it on, it went back to the same problem. The video driver failed to initialize. I'm still using the onboard gfx, and I'm thinking the problem is to do with the driver that Windows installed for the onboard gfx. I might be wrong though. Now how do I get it to log on to Windows like I did before?

Looks like your outdated motherboard drivers are the cause. Please run the Windows 7 upgrade advisor: Free Download PC Upgrade Advisor Windows 7 Hardware Programs Issues

What motherboard do you have? Use SIW if you don't know. You can also provide the computer model number.

If you can find a BIOS update, install it.

Thanks for the fast reply. I've been using the system for almost a year without any problems. Windows 7 was the only OS installed on this hard drive. The motherboard I'm using is a Biostar TA790GX A3+. Hmm I would like to update the drivers, but is there any way to do it without logging on to Windows, because I'm not able to log on.
