Can't Get Into Safe Mode Because Arrow Keys Stop Working

In an attempt to play a new video game my son changed the resolution on our monitor to something too high and now we get a black screen that says "monitor cannot display this video mode". Research online shows I should try to restart windows in safe mode, but when I try this the arrow keys on my keyboard don't work and I am forced to accept the default "normal mode" option (which loops back to the resolution issue above). I have tried two different keyboards that I know have working arrow keys normally, but they stop working when put on that particular PC (obviously I'm not on that PC now) clear.png

I tried changing the monitor but had the same resolution issues with it. I also tried the manual set up button on both monitors but could not make the resolution adjust that way.

So, I'm hoping someone can tell me how to get the arrow keys to work during reboot? Or anything else that might help? 

Thanks so much for any help,

Kat

It's an USB keyboard or PS 2 one?

It's a USB. My son figured out how to get into BIOS and the arrow keys work there. Can I get into safe mode from BIOS? I can't find anything for WIndows 7 in my searching online, but I am super busy this weekend and trying to do this with little bits of time so may not searching well. Thanks for your help.

When in the BIOS, look carefully in the menus and see if there is an option with a name like USB Legacy Mode for the keyboard, make sure it is enabled.

If you have another Windows 7 computer and the above does not help then create a System Repair Disk and do a System Restore to a date just before the change.
