Each time I format my hard diskamp; install windows the keyboard starts work for 7 / 8 days then again the keyboa? -

My keyboard is not working. Each time I format my hard diskamp; install windows the keyboard starts work for 7 / 8 days then again the keyboard does not work. Only sleep / awake buttons of the keyboard response. I have already changed 2 new keyboards. I checked these keyboards with other computer, keyboards are ok. But not working in my CPU. After formatting these keyboard works and goes down again by 7/8 days. Please give me a solution

Go to bios and look for ACPI suspend and try a different mode S1 or S2 or S3

It s most likely your motherboard is failing.
