Ok, now before I strart I want to abologise if I'm being an ***** here. So, the problem is that I get random bluescreens in vista, such as "memtest_manager" and "page_fault_in_nonpage_area". The bluescreens come whenever, whatever I'm doing, but more often when I'm playing or downloading something. All that I have read so far, suggest that I might have faulty RAM. Setup: EVGA 680i SLi motherboard 2x GeForce 8800Ultra 4x 2Gb G-Skill DDR2 800Mhz Intel Core Q6600 I remember testing my memory with the vista memory test, and at the first time it gave me an error report. I ran it again a while later, but didn't get any errors. I also read on these forums that I should clean the rams contact surfases which I did with contact cleaner and a can of compressed air but that didn't solve the problem. So, to make sure could someone tell me which of the minidumps to upload and check them for me? Thank you very much for your time.
