Well Rescently iv been having alot of HL2 problems during gameplay, iv had times where it unexpectedly would freeze during loading. the last issue was the weirdness. After it froze, All i heard My HD do was endlessly beep. It took alot of effort to boot back into windows too. I think it came close to killing my hd. either that or the games just sucking up all my ram causing my computer to freeze. i noteced on the system specs it recomended 512mb which is what i have. what else could be causing hl2 to freeze my pc?
