My 1 year old desktop PC: Gigabyte B75 board, i5 3570 processor, Corsair Vengeance 2x 4 GB 1600 MHz RAM, Antec 550W PSU, GTX 650Ti. All components' temps are within safe range at full load. PSU voltages within limits, except the +3.3 V line sometimes touches 3.4V.
It has started acting up since a few months ago.
The problem is this:
The system freezes suddenly while working and shuts off. Then it reboots automatically and falls into a boot loop before going to POST. It never boots up and gives continuous short beeps (signifying memory not correctly installed,) until I switch the RAMs from Blue-Blue slots to White-White slots. Then it goes on for another 2 days without a glitch, and starts acting up again, until I switch the RAMs into different slots.
During these two days before starting to act up, it runs stable as a rock.
Prime95: Four hours stable.
Furmark: 1 hour stable.
Memtest86+: 10 hours, no error.
I'd sent the board to Gigabyte to repair. They said they repaired it (under warranty,) but the problem didn't go away.
I know this kind of a predicament is extremely difficult to narrow down into a component and deal with, still all your kind inputs and suggestions are very much welcome. What do you think is causing the problem? Is it possible that a USB device like my keyboard or mouse or WiFi adapter can cause such problems?
Please help.
Thank you.
