Hi, I'm new here and I'm not even sure if I'm in the right section, but here I go, I have a windows xp home edition and its only a 4 months old (its a fairly new computer thats Vista ready). within the 3rd month, my command prompt is locked. now here are my symptoms: 1)when clicking any .exe that has no gui, or any bat or DOS files, i get this "Another program is currently using this file" 2)however, if i log in and click the command prompt the second it logs me in, I have access to CMD but many features still arent usable, such as "netstat.exe", etc. 3)when I do get CMD to open, closing it results in an error to "End Now" 4)when I get to open CMD, some .bat's and .exe's (no gui) open and disappear. other symptoms: 1)i once logged out of my screen name and each log in had a password lock on it, I do not put passwords on any login's (this only happened once) 2)random blue screen error crashes (happened for awhile then stopped) 3)random restarts, usually happens when running a bitcomet program, logging off another user and changing logins, after several hours of constant use. now I'm very computer savvy but not when it comes to these things. help is much appreciated.
