Hello! I am running a PC with Following specs(I know its stone age af)-
4GB DDR2 RAM
X5450 LGA 771 to LGA 775 mod (Currently replaced by an old e7500 for basic functionality)
Some Local mobo with G31 chipset, with 2014 phoenix bios.
I am facing a problem with a brand new(refurb ofc) X5450 which i bought a few days ago. On its first day, It was working just fine. On the second day I faced a problem. Windows Started freezing after a few minutes. Even the PC freezed when i was in the BIOS. It sometimes booted and worked well. But today the problem got even problematic. It was freezing everytime at the O Windows screen. I replaced it with my old e7500 and it was working fine. The seller says the cpu was tested pretty well before sending it to me . What could be the problem?
