I have a Gateway DX-4831 with 6GB ram, Intel Core I3, and a 1TBhdd. I have reloaded the OS four times to try and solve this problem with no effect. I have updated all drivers including a recommended BIOS update from Gateway. I get maybe 10 minutes of use and a lock up that lasts for 5 to 10 minutes. This is after being on for minutes or hours. There are no third party programs installed. I didn't use the system much when I first bought it and the warranty ran out before I realized the lockups were worse than the usual ones I get with XP. The OS has to be reloaded from a partition on the drive and not a disc. Could I just have a corrupted copy of windows? Microsoft and Gateway won't even talk to me without me giving them money. Any help or suggestions would be greatly appreciated. Thank you.
