A few weeks ago, I noticed I would push my power button on my computer and the light would power on, I would hear the fans running, but that was it. Nothing on the monitor. So I would wait, and turn it off, then try it again and no problem. Well, as time went on, it became more frequent. Harder to turn on, same thing, just requiring multiple attempts. Well I left my computer on more often, but recently moved. Same thing happened. I turned it off because I was going on vacation, not thinking, it was the last time I'll see it on... So for the past few days I've been sitting here turning it on and off on and off. All that is running is the HD, and fans. A few days ago, the monitor worked! It got all the way to the boot screen (press f10 press f2). But then froze. Same thing went on for a few more times. Then I get all the way to the Windows XP screen, then the screen goes dark and says "No Signal"... So I've disconnected everything, cleaned everything up, moved the Ram around and everything else. Still doing the same thing. Light on, fans on, and HD running. I've plugged my cable into my DVI slot (7950GT), and my on-board graphics slot. I have also hooked up my HDMI cable to my TV and the same results. So I've ruled out the graphics card. I've used two VGA cables thinking it might be something. Nope. Keyboard/Mouse doesn't light up either A few times I'll push it on and off and I'll hear the alarm beep. One beep every 5 seconds or so. Power supply is fine, it wouldn't run everything I believe. My only thing I can think of is possibly the motherboard. But why and how? My specs are Gateway GT5228 AMD Athlon 64 X2 4200+ 2 GB Ram 250 GB HD BFG GeForce 7950 (Computer has nvidia 6100 on board) PSU 600w Monitor plugged in using VGA cable with DVI adapter in computer. If someone could point out some tests I could do, or what may possibly be wrong with it, I would appreciate it. I held my breath and decided to give Gateway Tech Support and the guy said he wont talk to me until I pay the $59.99 for 30 mins. I said no thanks I was just wondering if you've had a problem with these or not or possibly just clue me in at what I should look at. Oh well go figure... Again, any help is greatly appreciated

gateway systems are notorious for weak powersupplies. Just because fans spin is no guarantee that other parts of the powersupply have not failed. Of course your problem may not be the powersupply but unless you can either test your system with a substitute known good PSU, or try your PSU in another otherwise known good system, you will not be able to move forward. Post back once you have determined whether or not the PSU is the problem. Goin' Fishin' (Some day)

The PSU in there is a custom one. 600w, the original one was like 200 or some crazy low amount... I'm gonna see if I can find the small one and try barebones just on that...we'll see

Now if I let it sit for a little bit, it loads up to the XP screen, and that is it. Stops running I guess. I can hear the GPU fan running but thats it. Then when I try to turn it back on, all I hear is the GPU fan so I wait a little bit and then it will do the same thing all over again....

Is the CPU fan running? It sounds like it might be overheating.

I believe it is...the fan blows from the side is running and it was working fine

A little more info about your PSU (make/model & amperage specs) would be helpful...600W doesn't mean anything. It's possible that one of the rails failed but is still putting out enough to spin a few fans, just not enough to fire up the entire system.
