Hey guys: Built my computer a few days ago, my specs: Q6600 with zalman 9500led cooler xfx 680i lt mobo Gainward 8800gt bliss pcx ocz reaper 800mhz 2gigs ram Corsair 620 PSU antec 900 case and a temporary 17inch dell lcd monitor. (no parts overclocked) So everything runs fine, game performance is great, rly happy with it all. However every couple of hours out of nowhere the screen will suddenly turn black without warning and stay that way, the computer continues to run (all fans, lights etc) and the only way to get the screen back is to reset the computer. The strange this is that these occurances dont follow any unique pattern, once it happened during crysis demo, then during portals, other times it happens just while i leave windows running with no other programs and just now browsing the internet. I've updated my nvidia graphics and mobo drivers to the newest avaliable but i just got another black screen then so it doesnt seem to have solved it. Anyone have any ideas what this is? Is it a faulty graphics card? i find it hard to believe cause as i've said, games and that run very well without a hitch. if anyone has any ideas, pls let us know, would be much appreciated. Regards.
