computer locks up

[Mr Pheer]

why does it lock up?

I blew all the dust out of it, made sure the fan on the cpu works good, changed the power supply. Its not doing anything new or cpu-intensive. No viruses or spyware. It will run for maybe 30 minutes, or sometimes for a couple hours, then it freezes.

Any ideas?
