Yesterday suddenly my keyboard and mouse stopped getting recognized by windows.
Things already done:
2) Safe mode restart
3) Anti-virus and Anti-Malware
4) Reinstallation of drivers
for both KB and Mouse.
5) changing to different USB ports
6) phone/ipod/ipad get charged on those USB thus seems ports are working fine and is not voltage issue.
Now problem is if give a "forced shutdown" even then my kb n mouse are not recognized. Like I cannot press "F8" to get safemode window, or "del" to enter BIOS. No error shown either. Only way to get them temporarily started is via plugging in PS/2 kb and mouse and giving a restart. Post restart both USB devices work for approximately 5 minutes and things got frozen again. Then unplug the USB devices, put in PS/2 devices give shut down etc.
So I felt corrupted windows and reinstalled entire windows but today morning again PC from sleep could not wake up with kb or mouse clicks.
This hasn't happened post any windows update thus restoring/reverting is not option. Loading in last recognized good config also does not solve problem.
Anyone faced something similar do let me know. on PS/2 connectors things work normal
Keyboard is Sidewinder X6, and mouse is a DeathAdder Black Edition, running Windows 7 64Bit edition. rest my config is there in signature.
