I have Windows Vista Home Basic. About 2 weeks ago my computer speed slowed down a lot. Everything would freeze up, the internet, which would normally take 5-10 seconds to open and start working, took almost 5 minutes to open. The mouse lagged when I moved it from one side of the screen to the other. Basicially, every normal function of the computer slowed down majorly.
I did a full defragment using O&O's defrag program. That didn't fix the problem so I went and downloaded the trial version of Advanced System Optimizer and did their scan. That didn't work either. I downloaded CCleaner and did their scan, still nothing. I have Registry Mechanic so I did their registry scan and fixed their errors, still the same problem. I did a full MalwareBytes Anti-malware scan(even used Rkill.exe before doing the scan) and it found nothing. I did the optimize memory thing that comes with ASO, and STILL the computer is really slow. Finally I turned to Kaspersky thinking maybe it was something the other scan didn't pick up. After a 6 hour scan, it still found nothing! I have about 89 GB remaining out of 143 GB.
Sure I don't have the best computer, and it's about 4 or 5 years old but it still doesn't make sense as to why the computer all of a sudden slowed down. Would it be a hardware issue?
Please, any help at all would be greatly appreciated!
Thanks for your time
