Go to your control panel and troubleshoot (then shoot the teenager) and see if that helps.
Yesterday, I made my weekly visit to TrendMico for the free housecall scan which revealed 26 virii which it could not clean. Then I fired up the BitDefender and ran it: it showed the 26 plus 2 more...after running it twice, the machine "appears" to be squeaky clean once more.
That would be TrendMicro...
"Morning, Loddy. I've already gone to my control panel. I'm wondering if my sound card has gone bad. My computer is old enough that things have gone bad. The hard drive, modem and motherboard have all been replaced in the last year and a half.
My nephew plants to come visit at Easter, and he's going to help me build a new computer. I'll just keep this one going until then. And, if it's still running, I'll keep this one up and running just to have a 2nd one around. For sentimental reasons, I guess.
