i bought a new powercolor x1600 pro agp video card. I got it installed and working but when I play a game it will let me play for about 2 seconds then it will freeze or the computer will still run but the monitor will say no signal and sometimes when i start the game I will get green vertical lines. The only games Ive tried so far is grand theft auto sa, sims2, and spyhunter. They games will work for a second but then those things will happen. technical support says to get a better power supply (mine is 300w) but I don't want to buy one if I don't have to plus why does it work but not for games?
