I'm new to the forum and hope I am posting in the right section. I have an issue where my computer freezes randomly. I've done a lot of searches and it seems like problem can be anything from softwares to hardwares. My problem does not have frequently. Once it happened right after I started windows and just browsing through files (in first 5 min since boot). Other times it happened after 6+ hours of using computer and gaming. More often, it freezes every once in a long time. What happens is screen freezes and I can't move anything. My computer doesn't make any louder noises and just stops being active. I have reinstalled the windows, tried using it without any drivers except video card but still happened after hours of gaming. This is a newly assembled computer and is stressing me out very much. Here are my computer specs: CPU: AMD 64 x2 Toledo 4800+ MOBO: K8N SLI ABIT board RAM: 4 sticks of Corsair valueselect 3200 1Gig (512mb a stick) two dual chan Graphic Card: Leadtek Winfast 7900GT 256mb PSU: Antec Truepower 2.0 500 Watts HDD: WD 7200RPM 250GB SATA All parts are brand new. I used to have BSOD problem with this comp (right after assemly) but went after I uninstalled the NFROCE firewall. I no longer have BSOD problem but comp still freezes once in a while. Any ideas? I would like to get this solved before my school starts next week.
