hopefully all you ntfs.org gurus can help me out with a recurring problem... several weeks ago, i noticed that applications (IE, OE, photoshop 7.0, steam, etc.) started failing (window accouncing that "this program has encountered a problem and needs to close" pops up). sometimes it happens, sometimes it doesn't. i'm behind a router with a built-in firewall and i have avg anti virus (fully updated) running constantly. i've done 2 virus scans in the last 2 days and have come up clean. i recently purchased another stick of ram. could this be the problem? just wondering if i should look elsewhere first instead of testing the ram out. *specs in case they're needed: amd 1.53ghz, 1.5gb sdram (3 sticks of 512mb - one is new as mentioned above), sndblaster live 5.1 gamer, gf fx 5600 ultra 128mb, 40gb western dig, 80gb western dig, linsys nic, 16x dvd, 12x hp 9500 cdrw.
