i tend to get them every once in a while and was just trying to think of the cheapest way to fix this problem. i know a variety of things can cause them from drivers, to faulty hardware, so seeing how my motherboard is fairly old M4NTD98 EVO by ASUS. Running AMD Athlon II X3 450 3.2, 4gb dual channel Crucial Ballistix ram 1600 sport 240 pin, toshiba 1tb hdd sata, 2 EVGA 9800GTX sli (16x16), raidmax psu 730 watt. i'm just trying to figure out what my problem would be, if anyone has any other suggestions please help me out.
