Given the story it's tough to repeat the usual. Let's hear more about make, model, story and such.
I will preface all this with I am not particularly knowledgeable regarding computer stuff, but am willing to learn!
OK I've been having a problem, similar to some other posts, where Windows Explorer (not internet explorer) seems to spontaneously stop responding. When it does, I can restart windows explorer and it always says "windows is checking for a solution" but never finds anything. Whenever this happens, which can be as often as every 5 minutes, it inexplicably disables my wireless adapter (belkin wireless g usb) which occasionally decides to not respond and not turn back on.
I have a relatively new dell desktop (bought it last year) with windows 7 (i think...)
Any help or suggestions would be appreciated, as I am at the end of my rope and ready to throw the whole darn thing out the window...
