Computer Crashed and won't start

I think it beeps right after it detects the graphics card. I would suspect that if your graphics card checks out, it is a CPU or Motherboard/chipset, of PSU issue that is stopping it from getting that far. It has to have a graphics card recognized before it goes on to detect and report on other peripherals - it hasn't even gotten to detecting any hard drives yet me thinks.

When you don't get a beep, it's either the power supply, or less so the cpu, and even much less so the mobo, in that order.
Unlikely the mobo. When they go, it's normally in their first month of use. Pretty much the same with the cpu. They go early in their life, if they go (overclocking or overheating are other issues). How long have you been using this mobo-cpu combination? Do you run 24/7?

When I was working, I had to replace 8 of 11 Thermaltakes I came across. I wouldn't trust them. The way you tested your psu is not definitive of its' ability to perform under a load.

If you have a really good friend, and one of you is handy around desktops, break his pc down temporarily and bring his psu to your machine & replace yours with his.

This will label or eliminate that part as the problem.

Alright so, I ran the pc without the VGA, won't post. Disconnected both VGA and DVD reader, won't post. Disconnected VGA, DVD reader, 1 HDD won't post. Disconnected VGA, DVD reader and both HDD, won't post. I can't really get another PSU cause the 2 friends I have that use desktop pc are out of town so I'll have to pay someone to check it out :/ (I hate to do this xD, I never had to pay someone to fix my computer)

Have you tried the BIOS clearing that essenbe linked to? I would try the third method of removing the CMOS battery and then short the two battery contacts to be sure the BIOS is cleared. Pull out the power cable from the PSU when you do this. This will re-set everything including the BIOS clock, which will go back to near the manufacturing date of the board.

I've had a lot of no POSTing. Some things to try:
Remove all but one DRAM stick, leave the one closest to the CPU.
Disconnect all drives from the motherboard.
IF you can get into BIOS now, go set the boot order and basic DRAM settings, nothing else. Power off, re-connect your OS drive only and see how it goes. This does sound like a bad board.

I tryed BIOS clearing without any changes, and I have never overclocked anything. Even if I did, the motherboard has a OC protection thingy and it resets itself if you fail to OC

Dreath:
Bringing it in for a techie to service will cost $95-$125 labor besides the part.
Try this first; it may solve the issue. Purchase an Antec Earthwatts (or Corsair) 750w, and replace your existing. At least you'll know you have quality in there.

It's not your video card; if IT was the culprit, you'd get a series of beeps. Hook it up along with your boot hd & let's see if you post and boot at that point with the new psu.

How long had you run this mobo-cpu combo?

Have you checked on the PSU and see if it is still functioning?

IF the psu is bad, the BIOS post won't get to memory check. Post won't even start.
