Hi I just installed a new Antec VP-450 450W ATX 12V v2.3 Power Supply and a Nvidia 9800 GT. I've tried on 2 occasions to launch TFT 2 and Payday: The Heist. I can launch them but once I join a game or start a game my computer proceeds to either lag/freeze and occasionally my monitor doesn't detect any input. Can someone help me? I was running LoL fine for about 3 hours and some Diablo 3 earlier
may be the power supply. looking at the power needs for the 9800 looks like nvidia wanted people to use a power supply with a 26amp rail. to see if it a power supply issue or a game issue..try runnig some bechmarks for gpus and see fi the error happens.
if it does i would try swaping the power supply out for a better unit.
