Hi all,

Not sure if I'm posting this in the right place but I'll give it a go:

My computer, a couple of years old, has started shutting itself down unexpectedly every 20 minutes or so which is obviously incredibly frustrating. The power lights all remain on, but it's essentially shut down, black screen, no sound, and can't be restarted without turning it off and on at the mains.

I figured it my be something to do with overheating, since the fan's been very noisy recently and I thought it might have been broken, but I've had a look and it now seems to be ok.

I can't run a virus scan since the comp shuts down before it completes.

Any advice please?

Thanks,

Stuart

Assume this is a desktop computer you are working with and not a laptop computer, I recommend starting with replacing the power supply and see if that helps out. How much power is your computer running?

Well...just because a visual look says that the fans are OK...it would be smarter to check temperatures after one of these abrupt shutdowns.

You can boot into the BIOS and check your CPU temperature there (normally). Just remember that it's Celsius, not Fahrenheit (if you do any conversions).

How many fans are installed in your system?

Is this a desktop or a laptop?

Thanks for the suggestions. It appears to be solved now... I'd recently installed AVG and it had only been doing it since then, so I played around a little and discovered that it was only shutting down during a virus scan with that. Weird.
