Okay, I just cleaned my PC today and now I'm having problems with my video card. It seems my PCI-E slot is damaged and my PC can't detect any video card installed (ATI 5570). This only happened minutes ago.
Prior that, my video card was working, it just takes 20-30 seconds before it posts. I tried my older video card (GeForce 8500GT but is nearly dead, busted capacitors) but that too isn't working.
My question: Is my video card dead or is it the PCI-E slot?
E6550 @ stock
ASUS P5KPL-VM G31 chipset
HEC 550w PSU
EDIT: Need to clarify things. When I said that my PC takes 20-30 seconds before it posts, it was after I assembled the parts after cleaning. Prior cleaning my PC, it posts normally (10-20 seconds from powering up to windows logon screen)
My bios is already the last one ASUS released so I'm stuck on that part. I still have not tested my video card but I'll do that first thing tomorrow morning.
I also don't think its the power supply as I haven't experienced any rproblems, besides both of my video cards are low on power and does not require a 6 pin. But I'll also check it tomorrow on my friend's PC.
By the way, how do I test my power supply? Do I just plug it on a different rig and test if it runs or do I need any tools like a voltmeter or something?
