Hello I wants to resolve a 2 months old problem on my pc. The problem is that PS2 keyboard and Mouse stops responding (40 to 50 minutes) after starting windows.While all other programs and songs works continuesly. But when I types Alt+Ctrl+Delete after 1 minute then again keyboard and mouse works well but for just 20 to 25 minuts, it hangs again. Please tells me what I should do.. I already have done these things to solve this problem but without success. 1. Format C and install winxp sp2, 2. Remove every PC components and then replace after cleaning. 3. Installed and checked for Viruses Kaspersky 2008 Updated, BitDefender v10 updated. But another important thing that is: by checking drive c from cmd it shows that there is a 16kb in bad sectors. Then I set the parameters on cmd chkdsk /r to shedule on restart. After restarting it checked disk for recovery. On 75% completion it stops for a huge time.. I need tech supporters to resolve this problem. Thanks System Specs: Computer Age: 2.5 years. Computer Location: Home PC ASUS Intel 865 Chipset motherboard with onboard 64mb graphics.
