A computer freezes at odd times at first you suspect the power supply or overheating but you have eliminated overheating and replaced tje power supply without solving the problem what do you do next?

Answer 1

Freezes could be anything from a virus to a bad piece of hardware. It could also be a particular computer program crashing in the background and grinding your computer to a hault.

What OS are you running?

What is the computer model?

What video card are you using? - a bad video card can cause this

Don't forget to look at the simplest devices like mice and keyboards. I had a bad keyboard that kept causing freezes. Replaced it and the problem vanished.

Does it simply lock up or do you get an error message?

How long has the computer been running before the freeze?

Although you say odd times, does the freeze occur after running a particular program?

Have you run a full virus and spyware scan?

There are just too many variables to determine what the culprit is. Before answering this question, you need to narrow down the characteristics of the problem for us.

I forgot to add, let me know the details and I'd be happy to try and help out on this issue. Freezes can be very frustrating and hard to diagnose. By replacing the power supply, you removed one of the big causes of freezeups. Now it's down to the strange and archane areas of computer tech support.

Answer 2

It is more likely to be the CPU overheating - are any of the case housing fans not working or are they full of dust? Is the CPU cover and motherboard covered in dust and fluff?
Next have a look to see if any of the memory chips have gone bad....I think you may be able to download some software to check this.
