This has been happening ever since I upgraded to a 64-bit and so far I can't seem to find an answer as to why/how I can fix it. I can play Counter-Strike all day with no crashes and it runs like a dream (which it better since it's pretty old). I go load up Counter-Strike Source, HL2, BF2 (only games I've tried so far) with the settings defaulted to my config and the games crash anywhere from seconds to a minute into playing. Only once has it not crashed within 1 minute. I've tried various things and I'm not sure what could be causing this. Here's my setup, so far my only real possible explantion is that the ram could be bad or just not working right. AMD 3200+ 64BIT (Venice core) ASUS A8V-Deluxe 1 GIG Mushkin SP3200 (2x512) ATI 9800 PRO 128Mb (Powercolor) Windows XP SP2 Thats all the important stuff. The reason I believe it maybe the ram is because of some of the reviews on newegg that have been posted lately. http://www.newegg.com/Product/Product.asp?Item=N82E16820146219 Also it's not posted on my compatibility list with the mobo. (I have had the ram for awhile before I bought the new mobo and cpu) I've tried underclocking the ram with no success either. Any suggestions? If I can prove it is the ram I'm just gonna buy some Kingston or Corsair.
