hi. i just bought a new online game and installed it with no problems. When i try to play it, after 2-4 minutes the screen will go black and i have to switch off my p.c. After reboot, if i let chkdsk run, it will freeze after a certain amount of time. Again, forcing me to switch off the p.c. I dont know if chkdsk is actually freezing or if its just taking a hell of a long time to do anything. I once left it overnight and it had not moved! My P.C's specs are: CPU - pentium 4e, 3400mhz RAM - 1 gb hard drive - 200gb OS - XP with SP2 Thanks very much!
