Computer won't boot.

Rainfall

So after some rousing Guild Wars 2 last night, I turn off my computer and go to bed. This morning, when I try to turn my computer on, the fans power up(at a far lower speed than usual) for about five seconds before powering down.
Then it repeated, endlessly cycling, until I switched off my power supply.

So my first thought was something obstructing the fan, but I cleaned them out and it's still doing the same damn thing. Any thoughts or advice?

Is it failing to POST or is it not even getting that far?

Not even getting that far. It's not generating beepcodes if I boot it without RAM or GPU, so it's prrrrobably the PSU, just wondering if there's any other possibilities.

Nah, in that case it's PSU or Mobo.

Have you had bad weather? It sounds like you have a power supply failure or a memory stick failure. I'd start by removing one stick, then the other, then both. See if it'll POST like that. Then I would disconnect the power to everything except the motherboard and the video card, and see if it'll boot.

If no, you have a PS failure, or something more serious (mobo / CPU).

He already tried booting with no RAM or graphics, so that rules out those.

I know some repair shops here will test your PSU for free. I don't know if it's a legitimate test or just hooking it into a rig they know works or what, but that may be away to get some guarantee before dropping cash on a new one.

This is properly unneeded to mention, but when seeking for system failures ALWAYS remember to disconnect hard drives and other types of storage.

First of all a really sick drive can cause issues in the rest of the system and secondly a sick system or just the process of repeated partial boot sequences can cause problems with the storage units!
