Vista - pc freezes intermittantly

Hi, My computer freezes a couple of times a day and I have to manually
restart. I have cleaned the fan and inside the pc but it still happens, Acer
assures me that is not a memory problem. I believe the vista image is
corrupted and there a lot of programs installed that I have to uninstall eg.
Norton antivirus, Esobi and CD burning software.
I have recently upgraded to windows 7 from Vista but it's still freezing, I
haven't got a Vista disc as it was preinstalled by Acer. I decided to
upgrade as I didn't lose my settings maybe that wasn't the way to go!
It could be the fan as it seemed a lot better in winter (I'm in Australia)
but I didn't want to go to the expense of buying a new power supply if that
didn't fix the problem.
My computer is an Acer T690, Intel Dual core, 2.2 ghz. It is not under
warranty any more as I voided that by installing '7'
Any more suggestions on what I can do?

Check that there is no dust build up on the CPU cooler.

You should be able to see the cooler fins clearly through the fan. If
you can't, remove the fan carefully - you don't want to break the seal
between the CPU and the heatsink - and clear the dust mat.

Hi,

Upgrading a malfunctioning machine is rarely a good idea. As the problem
continues, the source is probably a hardware component failing. If you run
the memory diagnostics (don't just listen to a manufacturer, run the
diagnostic tools in Windows or one of the many free ones available) and a
diagnostic on the hard drive and they both pass, then the next steps is to
either locate a qualified technician or swap in known-good parts starting
with the power supply, cpu, and if it still continues, the motherboard.
