Hey. I have this strange issue with my computer. I have been told its because of the PSU over heating, but it can't be.

Basically, I have my computer on for about 6 hours, and it would randomly crash.. Just turn off. And I wouldnt be able to turn it back on again. This, I gather would be because of the PC Overheating too fast, due to a crappy PSU.

But...How comes, when I turn my PC on at night, after leaving it off at my own will for around 6 hours, it goes off after only 5 mins. And I am unable to turn it back on. I feel the back of the PC, and check the heat, and its not even warm..

I have checked inside the PC, and everything seems in order, the PSU seems to be ok, and it is never too hot..I dont think.

So, I am confused..Is a fuse going? A battery dead? Im hoping that you guys can help me out with this one. If I get this problem sorted, Ill be sure to donate this time round!

Hi slow2die,

You won't be able to feel the power supply overheating, as your only feeling the case. The internal components have no contact with the case otherwise you would probably end up fried bacon!

There are two things to think about.

1) Is the fan working properly. If you put your hand about 3 inches away from the power supply, can you feel the air blowing out of the back? Is the fan just clogged up or seized, not working or turning very slowly.

2) Capacitor aging! This is something I bring up a lot on PCHF, because it is suprising how much this does make a difference. Over time, the power supply requires more and more power to operate, leaving less power for the PC.

I actually opened the case and checked the PSU, and it was an average heat for a PC. As in, ones I have worked with and built myself etc.

The fan is working properly, I checked the air blowing out, and I also opened the case and turned on the PC (dont worry, I work with PCs. :P) and checked all 3 fans were working, the one on the PSU, the one above the processor, and the one on my Nvidia GeForce 7600GT. :P

It all seems to be fine..

I understand your second point, when I got the 7600GT, I had to plug a new cable into the power, to run it..This took up power, and this may be the problem.

Maybe I need a PSU with more WATT?

Mine is 250-300, not sure..

i had the same problem well my comp took about 5-10 mins to start up in the morning so i got a new power supply problem solved for me any way

give it a shot

ek, I doubt it would be enough for a 7600. This site is good for calculating your PSU requirements: eXtreme Power Supply Calculator - What Power Supply Do I Need

Ah, not enough, that means this must be the problem then. I need a new PSU.
