I have an old custom build PC here that I bought off someone for cheap because it wouldn't boot. I went out and bought a new Corsair CX750M power supply and a 1TB Seagate Barracuda hard drive (7200rpm, 64mb cache, SATA III). The other parts included are as follows:

MSI n1996 graphics card (which I determined to be an AMD Radeon HD 4000 series)
MSI n1996 red motherboard
A dual-core Intel CPU
that I haven't determined yet (sorry)
3GB RAM (3x1Gb)
Generic DVD R/RW optical drive


Upon pressing the power button, the fans spun up, but I got no display or beep from the motherboard. I tried both DVI ports on the graphics card but I don't have a female-male VGA cable to test the motherboard display port (which is VGA male). I ensured the graphics card was in the slot properly and the fan did spin up. I read that RAM could cause a problem booting, so I removed a RAM stick. Still nothing. I tried removing another stick, leaving it in the slot closest to the CPU. This time the fans didn't even spin up. I put a stick back in and I am left with an unresponsive computer (no fans spin up). I tried resetting the CMOS by switching off the psu, removing the battery, moving the pin cap, pressing power, waiting, and returning everything back to how it was, but still no fans. The PSU is good because I hear the audio pop a bit when I turn on the switch.

Did it fail POST enough times to stop turning on? Do I need a new motherboard battery? Or maybe the motherboard itself failed? Possibly the CPU is bad? Let me know, i'm stuck.

I would try the battery: usually fixes those sorts of issues. If not, depends on if you're still under warranty. I would try testing the processor in a new motherboard if possible. That way, you have a brand new motherboard. If the CPU is faulty, simply replace it under warranty. If not, I would give tech support a call, they have great diagnostics

Update: I got the graphics card running fine in another computer, which narrows it to either the mobo battery, the mobo, or the CPU. Wouldn't there be error beeps if it was the CPU though? Or even for the battery I would imagine there would be error beeps...
