Power problem

[red baron]

This has been happening a lot lately and I'm not sure why. Every once in a while my computer just turns off. Not a random shutdown or anything, it suddenly just loses power and restarts.

I have:

Kingwin Mutant X Case with a 420W ps
ASUS A7N8X-X mobo -update 1010 bios
AMD Athlon XP 2800+ Barton 333MHz
ASUS nVidia 6600 256mb vid card
COOLER MASTER HAC-L82 80mm Sleeve Cooling Fan/Heatsink (supposed to run at 2200 rpms, is currently running steadily at about 2100~)


just your regular extras
cdrom
ram (512 x2)
hd (just trying to install a new one, but it's been crashing on me before installing the new hd)

My computer only recently started doing this, and I don't know why. I've had this computer since August of last year, so about 10 months.

I checked the cpu temp, and it's running at a 55C
I looked and found out that that was bad. So I now I'm unsure about what the problem is.

For a while I was thinking that my HD was bad, but I just installed the new one and it's still crapping out on me.

Now I'm starting to think the power supply is bad, or I have too much stuff in there for the 420W.

And now that I see that my cpu is running at such a high temp, I'm starting to think that I've fried my cpu, or at the very least, need a new, better fan.

Any suggestions or ideas? Any help is greatly appreciated.

Its most likely your PSU.

I'm not sure how hot Bartons usually run at, but if 55C is an idle temp, that is a little on the high side. If you have had the comp for 10mths now, try cleaning up the dust in the case and CPU fan the best you can.

Have a look at my guide to troubleshooting at the top of the Hardware Troubleshooting forum (which is where I am about to move this thread to). Do some of the free stuff in my guide before you decide to spend some money on a new PSU, etc
