I wasn't exactly sure where to post since since I don't actually know what's causing my problem. My computer would not boot up anymore and stopped at error code b2 and had a blank screen. Most of what I had read on that seemed to point toward the video card. So, I gave my video card to my friend to see if it would work. She said it was definitely the problem (could be wrong). I bought a new video card and tried to boot it up and got code b2 again. I removed the CMOS battery and tried again. This time it booted into the BIOS. I saved and exited and Windows started up. I downloaded the drivers from the AMD site, installed them and rebooted. I tried to play a game, but after a minute or two my game said the USB game pad was not plugged in. I tried to restart and got error code b2 again. I tried to clear the CMOS again and changed which SATA slot I was using and I finally got it to boot into the BIOS again. I set the BIOS, clicked save and restart or something like that and it got stuck at error code b2 again. The red boot device LED is on when it gets stuck at b2. I tried messing with the ram, nothing changed. I tried clearing the CMOS again by removing the battery and haven't been able to get it to go into the BIOS again. I tried booting with none of the USB stuff plugged in, no difference.

I have not even been able to get the BIOS to show again. I take the battery out and unplug and it does nothing. I have tried several times. The monitor is receiving a signal from the video card, but it is a blank screen and still stops on b2 with the boot led lit up.

I tried unplugging all of my usb devices and unplugging the power to the front USB slots. Now it takes a bit longer to stop on the b2 error. The DRAM LED comes on for a couple seconds and turns off, then the VGA LED comes on for a few seconds and goes off and finally, it ends on error code b2 with only the boot device LED on. I seem to remember stopping working in the first place right after I had moved it a little and thinking that was weird.

Thanks for any replies and help.

I built this PC almost three years ago. So, I think, it's probably not under warranty anymore. This is only problem it ever had. Is it pretty certain that the motherboard is the problem? Is it possible that the PSU is eating video cards? Thanks for the help.
