im having a little bit of an issue here. my computer is acting very very strange. if its not one thing its the next. I used to have a problem when my video card would malfunction and the graphics on any program would twist and turn, freezing my computer (or shutting off my video card). since then I replaced the video card and this problem stopped, but right at the end of my old video card another issue popped up. booting would get stuck at the windows loading screen and sometimes on the first screen to come up, the bios screen. After about 8 trys my computer will get past both of the points and acually start up. Just recently it has started a new problem, after I finally get it started it now wants to freeze randomly while im in the middle of anything and shut my video card off (brand new video card). I thought this may have been a virus so I switched hard drives, and its still happening. this cant be an issue with my power supply, thats new too. the only thing is my mother board but im not sure. my mother board does have a warranty, should I replace it along with the cpu and heatsink? or is there another problem going on? or is this an easy fix im just not seeing?
