Slow Operation Speeds
Recently, over the last 2 weeks or so, my PC has been running much slower than it should. This includes boot times, load times, program startup times etc. I have attempted to locate a cause, but have been unsuccessful in doing so.
As far as I know, it is NOT software related, as I have tried rollbacks by restoring and have reinstalled windows.
Memory usage is quite low at all times, as usual (Under 50%), and CPU usage at times is under load but not always.
I have checked temps of hardware and it all seems to be running at more than acceptable temperatures...
I don't know if this would have any effect, but a long while back the Heatsink fan on the CPU died, and I had to replace it. During this time the computer was shutting down due to excess CPU temperatures and it was a while before I realised what was causing the problem (Thought it was software related shutdowns, tried reinstalling windows etc and during the attempts and research the PC shut off numerous times)
Sometimes during the slow loading, there is a kind of "crackling" sounding noise coming from the computer, not similar to that of the usual hard drive sounds.
I am running Windows 7 Professional 64-Bit.
Any help you could give would be great, and any further info you may require I can provide.
