PC intermitently freezes up for a few seconds every five or so minutes


Tested hdd - passed
Tested memory - passed

The fan was quite dusty - perhaps that's all it was.

Is there a way to stress test the PC ?

Have you looked in the Windows Event logs to determine if there are any warnings or errors occurring every five minutes?  (I've see display drivers fail in this way before, but it would put a notice in the System event log...)

If you want to stress the hardware, taking the OS/drivers out of the loop... you could try the Ultimate Boot CD which includes several diagnostic/stress testing utilities.

Well no, not exactly. What you could try if this continious you can temporarily disable the AV on your machine and see if the issue persists. If it does this is usually casued by On-Access Scanning Policies. Which are usually enabled b default.

when it freezes, is that in one program - or in all?
is it downloading  - or installing softwares or updates?
