ya no i think i solved the virtual memory problem...im leaning more towards a messed up processor or ram...but i was wondering if service pack 2 was worth downloading or not..and if it would help my situation any..my computer reboots, alot...if i have a convo or 2 on msn, music match jukebox playing, and im playing a stupid web game such as bejewelled, it reboots...i have 512mb of ram and an AMD 1800+ processor...it should be able to handle it, and i know it isnt overheating cuz the hottest my cpu gets is about 42C...also i've had problems with this computer since i built it...i tried switching ram and this comp worked perfectly fine with different ram but this ram also worked perfectly fine in a dif comp...so then i tried to format and re-install and it worked good for a while then started rebooting alot then it just sorta fixed itself n now its being gay again...i've scanned it with at least 5 or 6 dif anti virus/trojan n they find nothing. I clean my registry with regsupreme every so often and remove my spyware every few days....soooo suggestions?
