I have Windows Vista on my PC. Two days ago, the computer just became very, very slow. Launching a website takes a good 20 seconds or more, and waiting for even control panel to start was excruciating. I tried to clean up the temporary internet files, saved browsing history, etc., but it didn't seem to help much. I also scanned the computer using Malwarebytes' Anti-Malware, but didn't find any infection. I am baffled at what could be causing the significant slowdown of the computer.
Your insight would be greatly appreciated!
