I have a hp PC m1170n and it does turn on but the cooling fans are at full rpm. the hd is good and I also get no video. so Im thinking its the power supply. funny thing is is that even though it does turn on there is no light on the power switch is does have a light ist just not on and leds dont burn out in 2 years. the system specs are Pentium 4, 200 gig hd. 512 mgb of ram. its a media center hp the vid card is a ATI Radion x300 se which is a pci-e type card with 128 mgb of memory. So any ideas on why this might not be booting? Could it be the power supply?

yeah I have removed everything and I did clean out all the dust from the proscessor. I also tested the clock battery and its good. nothing is loose. I also thought bad memory. I did put a regular pci video card in and nothin. so I dunno.

I'm assuming you can tell from the lack of disk activity that it's not just your video card.
I fix PC's and I have an Antec PS tester. Power supplies have several voltages, so it is quite normal for only one part of it to fail. As long as 12V works, your fans will spin, but you need 5V and 3.3, too.

In my experience when the fans are running full RPM (too fast) immediately when turning it on, it's either the motherboard or the PSU. Low voltage, or missing voltages, will still power the fans and maybe a hard drive, but not everything. Power supplies are much cheaper, and easier to replace so I would try that first.

It can't be the power supply becuse everthing boots up. Did you ever try to open up the pc and make sure the AGP or PCI Express is not loose. If that doesn't work try getting a new video card.

Before judging the power supply, I think it's better idea to check internal components by removing every card and devices in it and check is it turn on after removals. If yes, then might be some failure at the removed part.
