Just plain weird...

Hi Geeks,
I'm brand new here, so I hope I'm doing the right thing.

Problem: It seemed like all of a sudden Firefox just stopped working right and in using Explorer I've even noticed odd behavior (Not responding, slowness, etc...) It also seems that my machine is just running weird,(technical term.) I've downloaded DDS, ran it and have the files ready to send but was not sure if I should just send them without contacting anyone.

Thanks in advance for all, judgegarry
