Thanks for the replies guys.
Did you used to have the problem before your malware issues? Playing audio and video online could simply be an issue with your Internet connection. When you say playing is impossible, what does that mean, nothing comes out, stuttering.... Have you measured your upload and download speed? Speedtest is fine, if you avoid hitting the ads.
The problem was nonexistent before the malware issues. The Malware issues were resolved over a year ago.
Playing is impossible = audio seems to be jumbled / stuttering.
Download speeds are good. Other wireless computers on the network allow for multi-media streaming no issues. This computer is directly connected. I receive 21 Mbps x 4 Mbps.
What sort of things are sluggish? Page changes, mouse movements, programs starting up.........
Opening multiple browsers is one thing I noticed when I watched the Task Manager. It would jump up to 60% - 70% when doing that then go back down to 5%ish when it was all loaded. TBH I don't really know ALL of the symptoms on this machine because I don't use it. I'll ask my family when they're around what some of the other symptoms are and will report more. From my limited testing, I would say multiple programs running bogs it down. But even on a fresh reboot the audio issue is still present.
The System Idle process being 99 means it's not very busy! 71 processes does seem a bit high but these days every man and his dog wants to run a service on your PC. Mine are currently 54. I would have thought that during your malware removal exercise, others in this forum would have indicated what programs and services do not need to be running.
Thanks for the input on System Idle processes. It was quite a while ago we did the malware removal, but I remember posting some logs and IIRC it looked good to other members.
After about 15 hours - the defrag finally complete. Wow! Never seen that take so long haha! Guess there was a lot to do..or maybe this computer is just really slow?
Hamluis, I'm going to read more of what you posted in that link thoroughly. I was thinking maybe it was a browser issue too, so I installed a clean version of Chrome yesterday (Firefox is what's normally used on this computer), and I still noticed the jerky audio
