So I have an Asus M4A78-E mobo and 2x Radeon HD 4890s, and just recently updated to the new bios. Funny thing is it seems like ever since I updated to the new bios i get this error every time i start up "kdbsync.exe has stopped working".

At first I didn't think anything of it, untill I did some research, but my research turned up with a whole bunch of people talking about something they know nothing about....

I can't play any game, every game iv'e tried now works for about 5-20 seconds, then just crashes, no warning, no nothing. Also it makes everything else crash like Skype and Spotify. I've never dealt with anything like this before, and its just confusing me.

Im not happy about my cards not being supported by the newest drivers, i have to stick with the 12.6 drivers... I've tried everything uninstalling all my driver info and using drive sweeper. reinstalling the drivers but yet... nothing still does it....

I really need help with this guys...

Are you saying you updated the mobo BIOS? If so go back to the old one.

As for drivers for your cards, just stick with what was working  unless you had a serious issue with a new game, and even then then the application profile might be enough.

You should never update bios out of need to keep up to date, it should only be done when faced with hardware incompability issues.. like bought a new cpu, current bios doesn't support it.. THEN you update.
