After a recent storm, my keyboard and mouse became unresponsive and I could only get to the user select screen. I could go no further. I have pulled the CMOS battery to try to get into the BIOS on boot up and still cannot get in. When the screen flashes on boot up, I try to click on Delete to get into the BIOS, but, once again, cannot because my keyboard and mouse are not working. The USB ports appear O.K. If I enter a known device (jump drive), the light goes on the device. I tried a new USB keyboard, but cannot get it to be recognized since I cannot get to my home screen. Right now, after shutting the computer down by pushing the button several times, I get the Windows Startup Repair to open and it runs and then tells me that it wants to run System Restore. It has the "Run" button highlighted to run System Restore and all I have to do is click on "enter" on my keyboard to get it to run, but again, can't do that. Stuck. Any help would be appreciated.
