PC keeps shutting down

[chriskef]

Hi - when i bought my PC 1 year ago, it kept shutting down whilst in use. I
didn't receive any help from the shop so I lived with it. Now it shuts down
more frequently, every 40 minutes or so. When it shuts down, it doesn't allow
me to turn on again for about a minute. I tried the PC in another house and
it repeated the problem. I took it back to the shop and, typically, it stayed
on for 2 days, no recurrence of the problem. So, I took it home again and, of
course, it shut down after 40 mins or so.

Any advice well appreciated.

many times that can be a cooling issue, but in rare instances it can be a
weak power supply, as it warms, it gets weak and eventually shuts off.
have you tried a different power supply or using a UPS or line conditioner

More than likely it is overheating. You should be able to get into the BIOS
and check the temperatures. Do that immediately after one of those
shutdowns and as soon as you are able to bootup again. The computer may
require a good cleaning of the cpu heatsink and fans. Or, the contact
between the heatsink and cpu might not be that good and require reseating
after applying a fresh coat of thermal grease.

Cheers.

Sounds like an over heating problem. Where do you physically have your
computer located. If it is inside one of those small compartments that are
supplied in so many computer desks - that could be your problem. When you
take the computer in to the shop they just sit it on a bench where there is
plenty of "free air" around the physical box. This equals maximum air flow
for good cooling.

Try placing your computer on top of the desk. Does that solve your problem?

Check the CPU fan

Why would it work @ the shop and not @ home if it were the cpu fan??? If
anything, I would pop the case, blow/clean all the fan inlet/outlets and
then sit it in an open area and see what happens then.

This use to happen to my HP PC after a little over a year, i went out and
purchased Thermal Compound for the CPU and it worked. It may be an
overheating issue for you as well. Good luck.

Classic Power Supply overheating from defective or very dirty fan. Change the fan in the PS or change the PS
