One of my friends PCs is having intermittant freezing issues. He'll be doing anything (usually gaming but occasionally youtube has caused this) and the PC will lock up forcing a restart.
Last time I was there I ran a memtest, updated all his drivers, checked his temps, and ran Prime95 for half an hour to see if anything popped up and nothing seemed to. He claims he'll get a lot of stability for weeks and then it'll all crash down and he'll be unable to get half of surfing blogs in. He also says when it locks up the fan tends to go crazy - I'm not sure he knows which fan though. My gut instinct tells me this might be a hard disk issue - he has three, two mechanical hard drives (WD black 1tb), and a 128 GB Kingston SSDNow V200 - most ofhis games (and his OS) are on the SSD so I think it might be the issue.
Is there a good way to diagnose this one way or another? especially in terms of SSD diagnostic tools?
edit: forgot his specs
He's running an FX-8100, 8 GB of Kingston 1333 RAM, a Radeon 6850, the above three hard drives, and I believe either a 650 or 750w Corsair PSU. System was built about a year ago.
FX-6100 @ 4226 mhz, Cooler Master Hyper 212 Plus cooler with too much MX2 on the bottom, 8 GB of Slow DDR3, Packing a Velociraptor, Radeon 6950 which is big and black, Corsair 600T Special "Imperial Stormtrooper Wannabe" Edition.
