Crashing Computer, likely related to RAM or Motherboard, possibly Hard Drive

When my computer has just been turned on, or is under a heavy load, it sometimes will crash and freeze, forcing me to reset the computer. When it does so, it also emits a loud, bone jarring buzz from the speaker, leading me to believe it may be my MSI motherboard with on-board audio. I know for sure that it is not my processor or graphics card overheating; i have both temperatures monitored, and the processor is water cooled and rarely, if ever, rises over 45 degrees Celsius. I also suspect that it may be faulty Ram. I also have a suspicion that it may be the hard drive.

Ok so i ran Prime95, and within a few minutes my comp blue screen of deathed so???
I've never had problems with the blue screen of death; its definately not my processor, so can i assume that its faulty RAM?

Also, I'm 99.99% sure that it's not a leaking capacitor. In the recent past, a technician was out to help me solve a problem that involved my computer failing to boot; turned out to be a spec of thermal compound on mobo.
But anyway, I know thats not the problem, becuase it was doing this before I installed the water cooling device that led to the thermal compound.

 

Hi,

If you think you might have faulty RAM, you can run Memtest (or I think Microsoft has its own memory testing software as well )on it to see if it gives you any errors. You can also try booting with one stick of RAM at a time installed and see if one of them gives you errors when trying to boot. For the Hard drive, you can try running checkdisk on it to see if it can find any bad sectors on the drive.

 

I would really look at the hard drive a test it..

 

I think it is facing some kind of virus attack also you can try to check the SMPS functionality. If nothing works then you can always go for OS repair mode.
