What clean-up procedures, did you try to clean temporary files, and if so what tool did you use? Some temporary file removal tools are better than others.
Did you check amount of fragmentation?
Did you run a chkdsk C: /r, What were the results of chkdsk if you did run it ?
What malware/virus tool(s) did you use, and did you scan with more than one tool. Some scan just for malware and some scan for both viruses and malware.
Registry cleaners/optimizers are not recommended for several reasons. Registry cleaners are extremely powerful applications that can damage the Registry by using aggressive cleaning routines and cause your computer to become unable. Many articles on the internet describing problems with registry cleaners.
Open up Resource Monitor to find out what system resource is the most active. Click on the CPU tab and note percent usage, then click on Memory tab and note used physical memory, then let us know your results. You can then sort on each tab to find the processes and/or services that are using the most resources to narrow down the problem.
Hope this helps.
