Recently I purchased and built myself a Tom's Hardware build (this one, to be exact) and was quite pleased with it.
I wish that was all I had to say, but a couple weeks ago the thing just decided it was going to freeze randomly. No reason whatsoever for the change, it just started. Usually it only freezes when I start up a game, but at times it has frozen while viewing Youtube videos, surfing the web, or just starting up the machine. And sometimes it doesn't freeze at all for a whole day.
I have tried memtest (it froze during that, apparently marking it as a hardware issue) and replacing the PSU (didn't help at all, forty bucks down the drain ). Please help, I find it increasingly difficult to use my machine
see if you can get memtest running when the pc isnt giving you any trouble. results?
do a hd test as well.
freezing up can often be bad ram or a failing hd. the good thing is that your parts should all be under a warranty.
of course it could be a strange software glitch so before you assume hardware try a system restore to before you started having issues. if that doesnt work then do a fresh reinstall after wiping the hdd with a format. if that doesnt work then pursue the hardware components.
