Hello everyone,
after updating, my pc it's lagging all the time.
i have Athlon dual core X64 5000+, 4gb ram, Nvidia 8500gt, 500gb sata.
And i already done thigs, as a usual solution for any problems, Installed Malware, deep scanned, and find nothing.installed few Registry programs, and cleaned, and still having a problem. In my computer, clicking on advanced settings, in performance options, i reselected almost everything except smooth edges of screen fonts, for better performance, CCcleaner , cleaning everything, Avg didn't find anything, and when i browse on Google Chrome or Firefox, when i scroll up and down, it's like my (Lg Flatron L1918s) is on 10hz refresh rate.. not 72.. Same thing with browsing on pc, and typing.. and everything..
p.s. few days ago i reinstalled Windows 7.
Does someone have solution for me, please help me???!!!
