PC Cuts Display if bumped.

[DylanV]

When my of is sitting alone, my moving. everything works fine, I can browse the internet or play games, whatever. but if it is bumped slightly or move, it will immeditely cut the display, it won't turn off, but my monitor will just stop showing the screen. even if i u plug it or replug it again. to get display, i have to open my pc, turn it on it's side, and the only thing i do that can make it work is, move around the two ram sticks. I learned this trick from these forums a while ago, and it's the only thing that works, but now my of won't display if bumped. it's very frustrating because i have to open my of up constantly to make it work. Could there be a lose cable or is my mobo bad or what? please help.

Update: It happened again, so i'm now trying to move the ram all sorts of way, and no luck, my of powers in fine, but no display.
