Recently the receptionist's computer has become very slow. Receptionist reports random sounds coming from the computer and adds popping up randomly. I checked her computer thoroughly and could not find any malware after running avast and then later malware bytes. I cleaned up the registry, deleted some old programs, compressed old unused files, and disabled a few other uneccesary programs from running in the background.
However it did nothing and the computer pretty much goes into unresponvie mode after running something like malware bytes or excel.
Had to do it while in safe mode. Otherwise malware bytes could not run and you could not even bring up the task manager to kill processes or close unresponsive programs. It seems to get progressively worse with time. First it is just slow, then some programs become unresponsive, then any activity on the desktop becomes impossibe and no longer accepts any keyboard commands except for moving around the mouse icon which works normally without issue.
I could not find any of the reported random adds.
However I did notice that periodically the computer tower would become very loud. It also seems to shake slightly. I think it might be the fan and maybe something else but it louder than any fan speed I have ever heard. It is probably going at maximum possible output. It might have also been damaged from doing this which might be why it sounds so loud. I do not know for sure though. I have a program on my home computer that lets me control fan speed and even if all fans are running on max while the HDD is spinning and the DVD drive is spinning the combined sound would not match this recpetionists computer.
My current theory is that the CPU keeps overheating which is causing the fan to go nuts.
Also this sound does not appear to have any effect on how the computer performs in safe mode. In normal mode the computer tends to go into the sequence of unresponsiveness I described earlier.
The PC has over 3 Ghz processing speed but just under 900 MB RAM. I have not been able to get too much into it yet ebcause the receptionist has to use it all the time.
