First symptom: one of my web pages wouldn’t load, though all the others still do. Then my security antivirus program showed as non functioning. Once that was fixed, then I couldn’t connect to the internet. Got that fixed, then my printer wouldn’t print. Now my Windows Media Player doesn’t work and says no sound device is detected. My CD/DVD player connection is no longer detected.when I try to record files, though it recognized a CD if there is already a file recorded on it. This started 5 days ago, and the flaky computer tech I had here yesterday worked for 3 hours and couldn’t figure it out and then didn’t bother to show up today. Tried to run a couple scans over the net and both of them shut down before the scan finished!

Does this kind of activity suggest a virus or suggest damage to the hardware? If a virus, any suggestions? And please don’t tell me to get a new computer. My computer is only 3 months old, so the money has already been spent!
Have already tried system restore. Didn’t work. I had what is supposed to be one of the BEST antivirus/firewall programs on my computer, provided by my ISP (Charter Communications).
