Computer Dies.. PS Hot to the Touch... Dying PS?

Hi

I have a problem with my computer and I think it is the power supply.

Sometimes the computer completely dies.. when i put my hand by the power supply, it is hot. When i get it a minute to cool down and unplug it from the wall, then plug it back up, it will turn on.

It use to be whenever I did something taxing, like play world of warcraft.

Now it's happening every 20 minutes or so.

Is this a sign that the power supply is dying?

How old is the system? Power supplies lose capacity with age so an older PSU that was running near its capacity to begin with may now be over stressed. List your full system specs if you can including PSU make and model if you know them or can find them.

Do you happen to have another PSU that you could test with to see if it occurs even with a known good PSU? I wouldnt use a suspectly problematic PSU in a good system though to test it out as that risks the good system.

This is a homemade system.. Most of the system parts are about three years old, power supply included.

I don't really have another PS to try.

I did recently buy a new video card, but this problem happened before I upgraded.

The PSU should be at most warm, certainly not HOT.
Prior to your "recent" November 8 purchase the PSU should have had no problem running this system. Have you cleaned out the dirt/dust lately? I would make sure the case has good airflow with clean heat sinks and fans before I replaced the power supply. If you are overclocking, go back to stock speeds and see what happens. If it still runs hot after this then it's time for more and newer power.

I have to agree with the above poster that this sounds like it could be a heat related issue. Just had a similar problem with my build. Try taking the side off the case and directing a fan to blow on the case. Then see if you have the same problems. If not, its likely a heat issue. I have to manually up the fan speed on my gtx280 in order for everything to run cool in the case.

is it possible that the fan on the power supply is failing?

would it help if i bought more computer case fans?

i thought about buying a 10 dollar walmart fan and mounting it back there by the power supply to see if that would work, but i'd rather not resort to rigging a fan to the exterior of the case

Yes it's possible that the psu fan is failing. No, more fans won't help a bad psu fan problem. You should feel the airflow coming out the back of the psu. If you can't and it's HOT to the touch then you need to replace the fan, not jerry-rig another one behind the case.

check the fans, maybe one failed (cpu or video card)

The OP listed 3 video cards... an ATI 1900, an old AGP card and then a 4870. If you have two (or more) cards in the system at once, definitely consider pulling one... and set your CPU/GPU to stock clocks. This ain't the time for overclocking. Also, verify that nothing is obstructing the PSUs overflow... most PSUs intake from the bottom and exhaust air out the back.

the cpu fan looks like it is working.. the ps still gets very hot when it shuts down.. i have a box fan pointing at my open computer this time to see what happens

there are no obstructions to the bottom or exhaust air holes

"If you can't and it's HOT to the touch then you need to replace the fan, not jerry-rig another one behind the case. " <--- you can't replace a PSU fan, can you?!
