Issues since fitting Gainward Geforce GTX570 (Phantom).

I have had serious issues since installing my GTX570.
My system seems to run fine for a while and then seems to start locking up & freezing.
For example I have been playing Deus Ex:HR and quicksaves, normally instant, start taking longer and longer until finally I have to control-alt-del out.
This normally results in windows locking up and running painfully slow. And reinstalling windows is my only solution (check discs etc don’t work).
I had overclocked my i5-750 to 3.8GHz and it was tested and running stable never exceeding 80°C. I had this config before I replaced the card and never had a problem, although I am starting to think the extra power demands (im running a 750W PSU) might be contributing to my problems? I would really appreciate some advice.

Things I have tried:

• Reinstalling windows (Home ultimate SP1).
• Updated drivers (used drivermax to unsure all at new).
• Replaced hard drive (I had some issues after a while creating a partition, new HD solved that but not this).

My rig:

• CPU: Intel i5-750 (2.66GHz out of the box) – clocked at 3.8GHz. CPU Voltage 1.35
• Mobo: Gigabyte GA-P55-USB3 P55
• RAM: Corsair 4GB (2x2GB) DDR3 1600MHz
• GPU: Gainward Geforce GTX570 Phantom
• PSupply: Corsair A50 750W

If you have got this far, i thank you for taking the time to read this.

  1. Do you have an old video card you can try out? Your power supply seems to be sufficient.

    It may be that your video card is defective.
