Re: my computer keeps completely freezing
In this situation I'd always recommend backing up your files and reinstalling the operating system. This eliminates virtually all possibility of it being a software issue.
This could also be a hard drive issue. Is the hard drive making any clunking noises? When the PC freezes does the hard drive make a strange noise? Does the hard drive light flash as normal, or does it stay on all the time, stay off, or flash almost in a rhythmic way?
