Computer randomly freezes with hissing static noise

[battery9000]

Hello, I built my computer about a year ago, and right off the bat I'll list the specs..

Mobo- MSI P67A-GD65 (B3)
Cpu - i5 2500k
Gpu - XFX 6870 Black edition
RAM - 4X2GB Ripjaw memory DDR3
PSU - XFX 650W Modular
HDD - WD Caviar green 1TB
Windows 7 Home Premium

All's been going well, however recently the computer has been completely locking up, screen freezes (but stays on) and neither keyboard or mouse are responsive. This is always accompanied by a terrible hissing static type noise coming from my speakers, and sometimes my GPU fan will rev up to %100 speed. One thing I have noticed however, is that whenever this occurs, I will have some kind of Java app open (Minecraft, Runescape). It is extremely frustrating and it's happening quite often. I have Java 7 installed. Anybody with the same thing going on? Any fixes? Btw I'm not overclocking the CPU or GPU.

Thanks

have you looked in Event Viewer to see if there's a hint of what's going on?

Is the computer unstable during any kind of stress testing (GPU or CPU)? Or are you sure it completely specific to running a Java app?

Things to do if you haven't already: Check your temps. Make sure the heatsinks and air intakes/exhausts are free of dust. Update drivers for GPU and motherboard (if necessary). Try a BIOS update if necessary.

I'm fairly certain it's Java apps, as this only occurs when using Java. As for event viewer there's a couple of things...

Not sure what you can make of that...
But I will update drivers now.

Thanks

all that tells you is the computer shut down unexpectedly... http://support.microsoft.com/kb/2028504

you need to know what happened Before that event
