Try disabling all sound cards.
If it is not sound, update chipset drivers, maybe even bios, reinstall .net from MS site.
Monitor CPU cores and motherboard temps.
Monitor PSU output with some software or borrow another PSU from a friend. Try running with an older videocard to reduce PSU load or underclock your video card and CPU for testing purposes.
The program to clean drivers is called drivercleaner iirc.
Try running some modern video benchmarks with 100% videocard load.
