Specs: Windows 8
i have a real nice set up and i just recently got a new graphics card for my computer yesterday. the card is a EVGA 660 superclocked card i bought online, brand new, and whenever i play any game that uses 3d graphics such as sniper 2 or battlefield 3, the game crashes my ENTIRE computer and it wont unfreeze until i completely power it off and restart it myself. I have a windows 8 desktop HP pavilion that has a 500 watt power supply and 18 gb of ddr3 ram. can someone please help with diagnosing? i never had this problem with my old card.

✔ Best Answer
Please post the model number of your computer. Did it come with a 500W PSU or did you upgrade it? What are the amperage specs?

Did you uninstall the old graphics drivers before installing the new card? And assuming you were using onboard graphics, did you enter the BIOS & disable it plus unallocate any shared RAM? As for the card itself, did you connect the 6-pin PCIe plug? What about drivers, did you install the latest (just released a few days ago)?

and yes i did upgrade the power supply from 200 watts to 500. i dont believe i know how to enter bios but when the company installed it i believe they did that already. i did un install the 640 i had and put in the 660. it said it was compatible with the drivers already but i did a clean install anyways. my ram is 18 gb ddr3 and yes i have the latest installation. my specs are
