Before I go into the details, here is the entire spec of my system:
- Intel Q6600 @ 2.4 (Stock) - Scythe Ninja Cooler
Gigabyte EP43-D3SL - No modifications
4x 1GB OCZ PC8500 DDR2 SLI - Tested with Memtest and all fine
EVGA GTX 260 192 SSC - Thermalright HR-03 GTX cooler (Everything brand new & currently underclocked and undervolted)
Nesteq Semi-Fanless ASM 450w PSU
WD Velociraptor 150GB
Samsung HD501LJ 500GB
XP Pro SP3
Right, to the details....
Under normal desktop use (emails, internet, windowed videos, etc) I don't have an issue and the system could run for days if need be.
The issue happens or at least the only time I have seen it is when I watch full screen video/film. I'd be watching the film when for no apparent reason, the system will freeze (I can still see the film on the screen though it is frozen) and I cannot do anything other than reboot. I am not sure if its because im watching a film, but normally when I experience this crash the output through the speakers freezes too (sound like horrible high pitch loud static) and I end up running for the reset button to save my ears.
Having performed a reset, I check the system logs for anything suspicious...and nothing, no trace of anything un-normal at all, which leads me to believe its a hardware issue, but I have no idea what.
The only other thing that I have noticed is that sometimes after a reboot after the crash, I hear completely random cracks/pops/squeaks through the speakers which can be of varying volume. They sound a little like the pops/crackles you might find in a poorly made/ripped song some times.
I had an inkling it might be the graphics card so that was recently replaced as it needed upgrading anyway. (It was a 7800GT.)
I getting to the point where I'm considering replacing the motherboard as that seems to be the only other thing I can think of that might be wrong, but I don't want to buy one and realise it wasn't the issue. So any help, anything at all will be highly appreciated!
I will be willing to try anything anyone can suggest, especially considering the number of films I watch on this system and how incredibly annoying and film spoiling this crash is.
Thanks in advance for any suggestions you may have.
