I bought a Gaming PC about 6 months ago, it was fine for 2 weeks or so... then started getting BSOD's randomly when using the computer. Typical ones are: Fault in Non Paged Area Memory Management Bad Pool Header Bad Pool Caller When I started getting them I had these specs: AMD Athlon II x2 250 Asrock N68-S3 UCC 8GB DDR3 RAM ATI HD 5450 1GB GPU A standard 500W PSU Hitachi 1TB HDD Windows 7 Home Premium 64 bit I have no Idea what the problem is, I bought a brand new copy of Windows (Windows 7 Professional) and even added new hardware, I now have these specs: AMD Athlon II x2 250 Asrock N68-S3 UCC 8GB DDR3 RAM Radeon HD 6850 1GB GPU Antec 620W Gamers Editon PSU Sandisk 500GB Primary HDD Hitachi 1TB Secondary HDD Windows 7 Professional 64 bit I thought It might have had something to do with the HDD so I bought a new one, turned out it wasn't the problem. I upgraded my Graphics Card also which required a much better power supply. It doesn't happen all the time but it's very annoying. I have updated all drivers on my PC and I am still getting the BSOD's... I really don't know where to go from here... I'm curious to whether it's the RAM or not. If anyone could help me out I would greatly appreciate it. Thank You.
