This POS computer keeps jacking out on me. I think my graphics card is going south, but I don't want the hassle of buying and installing a new one. Problem is, I have a new 40 GB hard drive and new 24x10x40 CD burner that I most likely won't be able to use in a new PC. Do I spring for a new machine or put another band-aid on this one? It's a 500 mhz P3 w/256 MB ram. Opinions?
