Ok I've neglected my gaming duties for too long now. Started a new job beginning of 2012 and began having issues with ye 'ol gaming machine and now have the motivation to get 'er back online.
One day I started my computer and my video card (Nvidia 9800GT) would not work. I took it out, restarted with the onboard video on my Asus P5-KVM mobo. It booted up fine, so I shut it down and reinserted my graphics card. It worked up to the Windows 7 boot screen, then went black again. I took it out and stole my kid's 8600GT, powered up and still no response from the PCI-e slot. I swapped power supplies and still nothing. About a week after that, my sound quit.
So my question here is, could it be an issue with the BIOS, and I should perhaps reflash for good measures? Or is my motherboard history and I'm beating a dead horse trying to fix it?
