Im not tech savvy so bear with me. I just got a new Sapphire Radeon 5770 1G video card and a 600W power supply.
Before that I had an onboard graphics card and a 250W power supply.
But now after the new install, my computer starts crashing. I havent even tried playing the video game I got all this new stuff for, I open up a program thats moderately intensive and my computer crashes.
Can someone help me figure out whats causing the problem and how to fix it?

There is some more information. Let me know if you need some more.
try running memtest it a program to test you memory in your system. with the new video card you may be using a new range of ram and it has a bad bit. also a program called hardware monitor...with just your desktop up see and watch the power supply voltages. 12v 3.3 and 5v lines. if they go to low or too high they can cause issues. also check with the pc running your friend plugged the cpu fan in and it spinning..with the power off and the ps unplugged (some mother boards hold power). check that your ram dimms are seated...there the parts with the two white clips on them in the photo.. sometime when you move a pc from point a to point b things can get bounce. also check that all the plugs are pushed in. on the mb and drives.
Download Driver Sweeper.
Look in the control panel. Add remove programs or Programs and apps under win 7.
Look for the driver there. Uninstall it.
Reboot into safe mode and run driversweeper for your old card to remove left over remnants.
Reboot in normal mode and reinstall your new driver.
