So back in November of 2011, I bought a computer and didn't use it until Christmas. The graphics card wasn't seated properly, of which I fixed, but I was still getting graphical errors. So after buying a new graphics card and replacing it, I'm not getting any graphical errors. However, when changing pages sometimes, my screen will shake and I'll have a bit of static. This only lasts for a good half second, but it worries me. What should I do? Any and all help is appreciated.
if you have a laptop or another pc or another monitor i would see if the error follows the monitor or the video card. you could have a lcd screen that has a bad power supply. on your pc i would run memtest to check that the ram is fine. on some pre builts the onboard video uses some of the system ram. i would also run a gpu burn in test to see if you can force the error. if it non the gpu it could be the power supply dropping out.
