Display cutting out frequently
At first my counter-strike was starting to lag very badly after not having problems with it before, I tried reinstalling the game a number of times howver nothing happened, though my cs source and dod source which require alot higher specifications work fine. All of a sudden when I boot my computer the monitor cuts out when it gets to the Windows XP boot screen and I have to turn the computer off and back on a number of times before I can get to my login screen without it cutting off. Also when my computer goes into sleep for a long period of time the display will cut off after coming back on for a second. Note I have all the latest video card drivers installed. This problem points straight to my graphics card, so I installed a perfectly working older graphics card from my other computer, and had problems with that too, which is leading me to believe it could be something else! problem is I dont have a clue what to do now..
help would be appreciated
my hardware specs are the following:
AMD Athlon 64 3700+
GeCube Radeon 9600 Pro
Gigabye GA-K8NS Pro Mobo
by the way going a bit offtopic, I have two sticks of ram, a 512mb and 1gb stick, I have the 512 installed into the first slot. I was wondering if it makes any difference which slots the larger and smaller sticks are installed in. thanks
