Hello, I built this computer a few years back and have recently been getting random freezes / lock-ups with a buzzing noise, but no bsod specs: Intel core 2 quad q6600 @ 2.4Ghz Asus p5n-t deluxe OCZ DDR2 PC2-8500 FATAL1TY 4GB DUAL CHANNEL OCZ vertex 3 120Gb ssd WD 1TB HDD Rosewill 650w PSU Nvidia Geforce gts 250 SLI
I've tried replacing the psu, but no luck. I ran memtest for a good 2 hours but no errors happened. Also updated my SSD's firmware, no results either. All of my chipset, video, onboard audio drivers, and applied bios latest bios update. Oh and my temps an everything range from 40C - 55C. All help will be appreciated.
