Hello guys, I'm pretty new on the forums, so this is the first message of me. 5 days ago, I bought a PC. But the first time I tried to install Win7 x64, I got an error: "Windows cant install required files" etc. Then I removed a ram stick and it has installed successfully. But when Windows has started, everything started to stop working. I formatted after and after from different versions of windows' from different DVDs. And very often, I get BSODs. 2 of BSODs: 1- "MEMORY_MANAGEMENT" 2- "PAGE_FAULT_IN_NON_PAGED_AREA" My computer's specs: http://i.imgur.com/Amnwa.jpg I've run Memtest I got millions of errors. I've bought this PC with very much of difficulties of money that i've been saving for a long time and i'm really feeling down for that kind of errors. Everything stops working and BSOD almost every 10 mins Thanks a lot in advance guys.
