Frustrating PC issue

[Hajime]

Okay, so I have this PC giving weird, weird errors.

Specifically, three. I fix two, which were complaints about NTFS corruption.

However, I get stuck with a third one I can't fix normally - HARDWARE_IRQL_NOT_LESS_THAN_OR_EQUAL or whatever.

Fiddle with it a bit, can't boot into windows stably before it comes up, say screw it, replace the RAM.

Still no luck - same error.

I go to reinstall windows.

It freezes during the install process.

I replace the motherboard and processor, as well as upgrade the drives from PATA 120gb to SATA 250gb, and reinstall windows.

The install process completes successfully. I can boot into safe mode - but normal windows mode gives me a black screen.

So, thinking I had a problem with the cd drive, I replace that as well. Reinstall windows.

Still the same black screen.

I replace the PSU, go to power it up like normal. Nothing.

I use the old PSU. Still nothing.

I go back to the old mobo - still nothing.

Any tips or advice would be greatly appreciated.

So far, which part you have not replaced yet?

The case, the floppy drive (which is not connected), and the VGA card.

Shorted the PWSW pins.

Shorthand version of what was wrong - PC case powerbutton was defective. Wow. WTFMATE?

Your windows would not boot all the way? So you shorted them with a screw driver instead of using the power button and it booted up just fine?
