Well,
My friend have a laptop which monitor goes blank random times. I hooked it up to my monitor and it happened the same thing. However; when I take the memory out of the laptop and plug back in. It lasts long without screen going blank. I also set to never in the power management settings and no hibranation or nothing is set up.
I would like to know that what makes computer to work fine for a while after removing the memory and plug back in? Also, he had a virus, spyware and adaware infected hard drive, I did a dos format and when I try to install windows, it went half of the way and hangs up while in the screen in the place where it says creating files to be copied. Second time it copied half of the files before it stops. Third time I remove the memory and put back in, windows installation went without no errors. I did twice and worked great then the screen of the laptop goes blank again. Does anyone has a clue what is this mysterious problem could be? It seems that problem somewhat fix whenever I remove the memory and put it back in.
