Well about a 2 weeks ago my computer(desktop PC) has been Freezing and the only way to get it to work is to hold down the power button and restart. Now it had recommended a system restore which made the problem go away for like 1 day and a half but now its back again. Any ideas I had to do a disk check and it found some errors. Could the culprit be that i only have a 350watt psu when im supposed to have at least a 400 with my nvidia geforce 9600gt lp card. i upgraded from a 250 and figured that would suffice. I was thinking I would either have to replace psu/and hdd or what do you recommend. VISTA IS MY OS.
