i tried restarting, scanning my comp for virus and malware, defraged, cleaned my registry, deleted unimportant processes and start ups, but it all didn't work at all! one thing my friend said might be a problem is because i didn't update my antivirus software, hence, the virus got in and stayed in. somehow undetectable? :S
and no, it didn't start happening when i partitioned the drive. but the thing is, i've only had my comp for 4mths, so wtr it's d partitioning that caused it or not, i have no idea. it only started lagging a few weeks after partitioning, not immediately after..
