Windows 7: black screen followed by multi color lines

ok almost 2 months ago my computer blinked came back on and said a display driver had crashed ans was succsesfully recovered,well from then on out my screen was weird looking with lines ,text would dissapear ,and it was like this for a long time,so the other day my screen blinked and when it came back on my whole screen was multi colored and i could not see my desktop at all, now i read that it was probably just my video card going out so i uninstalled it thinking that ,would fix the problem...and it did,,,,for about 10 minutes and it did it again...so i have no clue whats going on, but i know i dont want to hear windows registery error cause i have alot on my comp that i would have to have saved and i shiver at the thought of the price of that...i mean i cannot see anything at all just alot of colors in small thin lines,.this is a home built comp, but it was made by someone who has been makeing comps for years so he knows what he is doing.....but hes way to busy for me to just call up, so any help would be amazing
if this is in the wrong section, sorry this is my 1st post

Boot in safe mode and see if the issue persists. If it does in safe mode, then it's most likely a hardware issue.

yeah its happend twice in Safe mode..... ive been on my regular windows now for about two hours without that problem...but who knows it might not do it again tonight & then ten times tomorrow so IDK?

I just had this happen on a computer that had a 512MB video card I had installed a year ago. The video card was toast. I was left with the 128MB card that came with the computer 4 years ago, because they don't make the 512MB card that died any more.

In my experiences when your screen going into discoloration it's normal suspect is a burned out GFX card. Can you post some of your system specs?
