My keyboard just stopped responding during boot. So I cannot go to BIOS or select system which I want to start. It is USB keyboard and it was working before. I borrowed PS2 keyboard and it also isn't working during boot.
Lately I have been having problems with hard disk. Once every 2-5 minutes LED was on for 30 seconds and win7 wasn't responsive. I connected disk to another controller on motherboard and seems it is working now. All that suggests that to me that that motherboard is broken. What can I check? Or maybe you have some other suggestions?
Edit:
For last 3-5 days I have been having problems with video driver. Computer can work for hours without any problem and then suddenly I have 'Display driver amdkmdap stopped responding and has successfully recovered.' every one or two minutes. And then it works ok again. But my keyboard wasn't responding during boot long before graphics driver problems.
