I just built my new computer a couple of days ago. Everything is working well, except when I enable SLI and open any games. It will play for a few seconds then freeze. I have to restart the computer to get it to respond again. The drivers are up to date. The connections are correct. My system specs: Windows Vista 64 Bit ASUS P6T6 WS Revolution LGA 1366 Intel X58 ATX Intel Motherboard OCZ Gold 12GB (6 x 2GB) DDR3 SDRAM EVGA 512-P3-N871-AR GeForce 9800 GTX(G92) x 2 Intel Core i7 Quad-Core Processor CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready Power Supply Please tell me if you need anymore information.
