I have a newly built custom system with Vista home premium, brand new Razer peripherals. We had a power outtage, the keyboard will not even power on now unless I use the ps2 port. When plugged into the ps2 port, all lights come on etc, but it does not work. Windows will not load in normal mode either. I need to have it start in safe mode, but I cannot select it without the keyboard. I have tried two USB keyboards in each of the 12 ports. No go. I have tried 2 different USB keyboards with the ps2 adapter, they light up but do not function. I cannot get into BIOS or start in safe mode. Windows will not load normally due to abupt power outtage I assume. Any ideas on how to get around this?

Use a PS2 keyboard

Are you connecting the PS/2 keyboard BEFORE you turn on the computer? PS/2 hardware is NOT hot swappable.

Yes, everything is plugged up when I turn it on. I am going to try a ps2 keyboard w/o the adapter if I can find one. I don't understand why USB keyboards are even made if they are USELESS when you really need a keyboard. Guess its a good idea to keep one of those yellowed old ps2s for times like this.

Do I understand you to say you are using an adapter on the PS/2 keyboard? EXACTLY what are you using? What type is the keyboard and what type of port are you connecting it to? Are the keyboard and/or mouse wireless?

"I don't understand why USB keyboards are even made if they are USELESS when you really need a keyboard" I don't know why anyone uses a USB keyboard in the 1st place? I realize that there are some that have all sorts of bells & whistles that require USB & I understand it's necessary for wireless keyboards, but in most cases, it's just a waste of a USB port. IMO, if the PS/2 is available, you should use it.
