Hi.. I've an 860 mhz, celeron PC, with 128 mb ram. I ve got hw accelerator card.I had loaded a Prince of Persia 3d game in my PC. It ran very well in the beginning.
But all of sudden PC started hanging in between games. Now this habbit has grown so strong that now even the dos version of it hangs the PC.
Also other games like roadrash (which I think requires very low ram) also hang the PC.
I don't know what could be the problem.. could any one suggest me remedy.

I know you have probably already done this, but just in case, make sure and quit any programs that are running in the background by hitting CTRL ALT DEL and ending all tasks that aren't necessary to run your pc/the game.

Does your computer freeze completely (to the point where restart is only option), or can you Ctrl, Alt, Del, and end the game to unfreeze the system?
