Hey,

(First of all, sorry if this is the wrong place to post this topic)

Im having some problems with my PC and I could do with some help trying to diagnose the problem, I think its HDD related but I can’t be sure.

2 days ago my PC was running fine, nothing wrong with it.
Yesterday morning I turned the PC on and started copying some files to a flash drive, I went to the bathroom and when I got back the PC had restarted for some unknown reason. As far as I know the only think I have on my PC that can force restarts is Microsoft updates, but I checked that update log and nothing had been installed on this day.

I had to go out so I left the PC on, now usually it will go on automatic standby if its left for X amount of time but when I got back home it had fully shutdown. This had me alarmed but I turned it back on and it seemed to be working fine.
(Just to clarify know one had access to this room so it can’t have been shutdown manually by anyone)

So I decided to play a bit of WoW and it was all running fine for about 10 minutes and then a chain reaction of program freezes began, first Firefox completely locked up so I opened up task manager this causes WoW to crash and then explorer crashed, I managed to end task for everything but then the computer completely crashed I couldn’t access anything and I had to turn the power off.

I kept rebooting the PC but it kept failing to load windows(Win7) on my main hard drive, I then tried to load Vista on my second hard drive, but it took maybe 15 minutes for it load.
However once I had vista loaded it seemed to work fine, there was a few short "program not responding" but nothing locked up completely.
My main hard drive then started working again and was able to load windows (Win7-64bit) I played around for a bit to see if the problem continues and it did.
I went back to my vista drive and I ran checkdisk as well as all of the tests on the Seagate tool for windows and no errors were found.

While on my Windows7 HDD I’ve monitored the memory and CPU usages and they are never any different during a system lockup than when it is running normally so this leads me to believe the problem is related to the hard drive, but I’ve run all of these tests and they have returned no errors

Another thing to note is that since installing the hard drive I have Windows7 installed on it has occasionally made some "unhealthy" noises, but during these unhealthy noise periods my PCs performance has never been altered in anyway.

I had not installed any new software or hardware the day before these problems started and my antivirus and other security software is fully up to date, so I can be pretty sure it’s not a virus problem.


If it helps the specs are:

Main HDD: western digital 500g - Windows7 64bit OS
2nd HDD: western digital 250g - Vista 32bit OS
RAM: 6 GB
CPU: (old~) Intel quad core

Sorry for the long post, but I wanted to try and be as clear as I could about the situation.

If anyone has any suggestions, answers of further tests I could perform than please let me know, it would be greatly appreciated.

Thanks,
Magnumwolf
 
Chances of both HDD's being faulty are pretty slim, I suggest that you disable (via removing power cable) one hard drive at a time and run the OS on the only remaining HDD that has power.
Doing this will help determine if the problem is HDD related, ie If the system starts working fine with one of the HDD's disabled then it would strongly suggest that the HDD that has been isolated is the problem, however if you still get these problems when you are only running each HDD on it's own then it would strongly suggest that the problem is unlikely to be HDD related and that you should try testing other hardware.

What does the Event Log say if anything immediately prior to and after the shutdown/reboot? If it's an event writing to the log it might give you some clues as to what is causing the issue.
 
Try keying in "Event Viewer" on the Start Menu search, select it and press enter.

You can also access it via right clicking "my computer" either from desktop or start menu and Manage, then selecting the Event Viewer from the left hand pane.
 
my Win7 HDD ended up becoming completely inaccessable so i unplugged it, my Vista drive still seems a bit slow at loading, but its much quicker than it was.

For now my vista drive seems to be holding out, i will update if the problems returns
