Ok, so I was having problem with my X800pro where it didn't like to seat properly and if it wasn't sitting just right it wouldn't work. The other day I was hooking up my second monitor and afterwards I wouldn't get any video upon booting. I tried moving the card around and still nothing. I went ahead and swapped cases as I had been planning and tried to boot again afterwards. I eventually gave up and assumed that the card finally bit the dust, so I went ahead and ordered a 7800gtx and new motherboard with PCI-E.

I received the new motherboard and went ahead and swapped it in along with the new video card. I still have the same problem. I was able to borrow a stick of memory from a friend and try that and had no change. The only other thing that I can think of is either the power supply or processor. Neither of which makes any sense. The power supply is only about 4 months old, and is an Antec NEO 480w, if i remember correctly.

Anyone have any suggestions or ideas before I go out and spend a bunch of money to replace everything else and end up wtih a new computer?
 
Do you hear any beeps from POST? Can you borrow a power supply from a friend to see what's causing the problem.
 
Nope, no beeps what so ever. Hard drive spins up, everything else powers up as well, but no video. I might go out and buy a new power supply to test.
 
ok, ended up being the power supply. I replaced it with a 500w Antec Smartpower. It worked fine last night, ran for a few hours and I was able to restart a few times without any problems. I tried to power up this morning, and now I'm getting the same problem, of no video/no post.
 
I'd say the CPU is dying if you replaced the power, memory and motherboard.
 
Ok, but that doesn't make a lot of sense. When I first got the new motherboard and video card, I was still using the original power supply and it wouldn't work. As soon as I swapped in the new power supply it worked fine, until the next day. So could a faulty processor cause problems with the motherboard? Also, with the new power supply (when it was still working), i tried using my original video card and motherboard, plus 1 extra motherboard, and it wouldn't work. So i'm thinking that original video card is bad as well.
 
Im still flagging the CPU as the culprit, or maybe something is causing the power supplies to go bad...
 
Yea, i don't know. Last night before going to bed, i hit the power button again for blank and giggles, and it started up. Been running fine all night and day, including several restarts. I'm afraid to completely power it off though.
