At start up, PC has gotten slow. Also has audible noises ( sounds like morse code) coming from hard drive (not through speakers). Never had sounds before. Also noticed PC became slow. In the process of checking for viruses and malware. Also ran system restore to a few days prior but it didn't seem to help.

This is what I have;

Avast
Commodo
Threatfire ( had this but it didn't want to work right the other the day so it got ousted. I only ran it occasionally)
SpywareBlaster
Malware-bytes ( only run on occasion to double-check)

Working on the full checks to the system. Will let you know results.

Took care of the dust bunnies with the trusty air compressor (dialed down to about 40 PSI) . Also ran a check disc program at start-up. I think it repaired some files in stage 2 of the 5. I didn't oil the fan because it's running fine. If it ain't broke don't fix it. Shut it down a couple of times and re-started. No noises or strange screens. Start-up seems back to normal. Not sure what did the trick but it all seems fine.


Once again, THANKS
