Computer turned off while playing and now wont turn back on?

[Hellasweet]

Hi all, I have a dilemma for you all. I was playing a game ( Fallout 3 ) and all of a sudden my computer just turns off. I try to turn it back on but it wont stay on. When I pressed the power button the fans came on for a brief moment then shut off. This happened a few more times and finally the computer came back to life. But now the monitor is not getting a signal from the comp and also the keyboard does not work. everything has been plugged in and I have not even touched the case for months so I don't know what is up. I upgraded this thing in 2005 so maybe its time for a new setup? Let me know if my computer can be saved or if I should start over. Thanks dudes!

here are the specs:

Mobo- BFG TechForce 4 Ultra 939 NVIDIA nforce 4 ultra ATX AMD
Processor - AMD athlon 64 3200 + MMX 3D Now 2.0 ghz
Mem: 1 GB
Graphics card : GeForce 8600 GTS
HD- 250 GB capacity


Let me know if you need any more info than that.

First thing that pops into my mind is a broken fan on either your cpu or gpu. Open your case, turn your pc on and check if the fans on either work

either a broken fan or a fried motherboard

What kind off power supply unit do you have btw?

[Hellasweet]

It's not broken fan because the computer is on right now and all three fans are running just fine. I just can't see anything because the keyboard is not responding and the monitor is not getting a signal.The power supply is a BFG 550W I believe.

I would be playing Fallout 3 and it would slow down a lot when lot of things were happening, like the computer could not take it. It did this every time I played a big game like fallout.

I just tried to use my keyboard on my gf's computer and it would not turn on. god,is the keyboard fried too? I've never had a catastrophic failure like this happen before.

I would have suggested overheating problems, you said the case hasn't been touched in months, dust collected and cause overheating. Now that you said the keyboard doesn't work is a bit weirder... Give it a good clean my idea first and check the heat paste on the CPU... heat paste lasts about 3 years, so you may need to reapply paste to the CPU... Good luck

I think its totally trashed. When I turn it on it does not boot up, it just sits there. I dont hear any of the boot up noises or beeps that it usually makes.The CD tray does not work and i even hooked up a new hard drive thinking that was the problem, but nothing changed. It just sits there.

My 1st guess would be the power supply followed by the mobo.

Yea I agree with slay now... probably one of those 2...

I think Slay's right.
