Computer Failure Mystery

[Ruok2bu]

2 days ago my hard drive failed. It happened suddenly with little warning. There were no bad sectors and all S.M.A.R.T. information reported were all in the safe ranges.

The hard drive suddenly out of nowhere started making a high pitch grinding sound every few minutes. Windows started loading everything really slowly and then it kept freezing and crashing. I was able to recover the majority of the data though (gotta love the freezer trick).

Now, 2 day's later my video card has died. I was playing Wasteland 2 and a few hours ago the screen froze and green squares appeared everywhere. Then the computer restarted and there were green squares and lines all over the bios screen. I removed the video card and im now using onboard video which isn't suffering from this issue.

I have my computer protected by 2 surge protectors (plugged into same wall outlet) but my area has had a lot of brown outs during this summer while my computer was on.

Any idea what's happening? Is my PSU the cause of all this?

P.S. My PSU isn't a bad noname brand either, its an expensive Corsair HW 1000 Watt.

I am just curious why you would think that a hard drive making a grinding noise was related to the psu? Like you think it was'nt spinning correctly any more due to loss of power? All that aside, are you over clocking anything by chance?

I dont know, i just find it odd that 2 things failed so close to each other. I had a problem a few years ago where i had a cheap PSU that died and it took out the motherboard and all the hard drives too.

I dont overclock anything.

you really don't have a lot of options on the "what it could be" its either overheating.. if you know its not that then psu or dying parts.. as you said probably because of the psu.
