hi, I've hit yet another problem. last night (and a few other times) the display goes crazy (not sure how to describe it) but can still change volume with my keyboard so i don't think its freezing. I've waited for the display to go back to normal but it doesn't so i have to turn it off but when i try to turn it back on it shuts off before it gets to the boot screen. also, when i turn the main switch (on the PSU) off then back on the computer starts itself which it usually doesn't do. I've tried unplugging the HDD's, usb headers, network card and re-seating the ram chip. it did work again but i have skipped any trouble shooting other times and it's worked also. this is confusing me (and probably all of you) but i'm hoping some one could shed some light on this problem of mine.
