@pcgeek: Yes, I've tried re-installing the CPU a few times (safely cleaned + new paste each time) and no visibly bent pins. I'm thinking the CPU might be failing, or the CPU slot or fan brackets might be the cause. This is why I'm hoping someone with similar components can try my basic components with their confirmed working parts so that I know which might need replacing. Each of these items when hot (latest) cost nearly 1,100QR per. Prices haven't dropped much, and would increase to buy again here in Doha (w/shipping). =^)
