Nvidia card constantly crashes?

I have a GTX 660 with the latest possible driver installed. It will be fine for awhile but at some point just start crashing like crazy. I have 5 120mm fans keeping it at good temp and the fan speed of the card to 60 which is the highest it will go but still it does it. I have no idea why and Windows is always switching to basic for no reason.

Helo!

Check the power supply of the system. Gtx 660 has a high power consumption. If you open an application the cpu and the video card will consume a lot of power supply. Look at its TDP it's 140w without load and 296w with load.

Hope this helps you. xd
