I am in desperate need of help here. The other nite my pc died, and thinking it was the PSU i bought a new one which turned out to be $100 down the tubes. The problem is apparently the mobo, the core2duo, or the video card. The ram and drive are the only other things, and i've eliminated those. It froze up on me one nite, and when i tried to restart it with the button on the tower it wouldn't start. Let me describe exactly what happens when i try to start it. It does any of three things when i try and start it....
1)-starts and goes to the post screen where it counts the ram and all that, but freezes about 1/2 way down the page and won't respond to any key entries. (using a PS2 for testing, not usb)
2)-screen stays dark and nothing happens.
3)-LED's go on, then it turns itself off in about 5 seconds. Then it turns itself back on a couple seconds later, then in 3 seconds back off. It repeats this infinitum.
It does these 3 things somewhat randomly;y, but for the most part it does #1 first after it's been sitting for any length of time, then second try it does #2, then after a few more tries it starts doing #3.
So to me it sounds like a heat issue which i assume makes it most likely the mobo. but the thing is, i need to me much more sure than my non-tech mind can be. because each time i make a mistake in determining the wrong part that is the problem, i'm out another few hundred $ as i was by buying a new un-needed PSU. Please help if you can, as i am lost w/o my PC and can barely afford to replace 1 more part let alone all of them. Oh, and i forgot to mention it also sometimes goes to the 2nd screen where it lists PCI devices. But thats rare, and as in all other scenarios at no time will it respond to any key entries, so no chance of ever getting into the bios or starting from the windows CD. Thank you.
