Asus comp dead after keyboard driver install

I downloaded a new driver for my veiwsonic keyboard now my computer will not start after reboot. I have no video or sound. I removed my battery on my p5e board and left it out for 20 minutes to reset my cmos. I am not getting any error codes off my board speaker and the computer will not reboot. The board is only 4 months old and was working fine up until the driver install. Does anyone have any ideas on how to fix my issue. I also tried to install my drivers from my factory cd but to no avail .

Yes I know this does not make any sense, but the keyboard works fine on my other comp I am using it now. After the driver install the keyboard would not work at all so I rebooted my comp and that is when my board would not post. It may be a coincidence since I see many people are having similar issues with the p5e board. This is sad since I replaced my asus striker board with this one and I am having the same problems. And that board lasted only 2 weeks. My video card , sound card, and memory all check out good. I hope I don' t have to send this card back for warranty work too . It will be the last time I buy anything from Asus. I have checked for shorts and had a local computer store check,also they are the ones who installed my p5e. How long should you let the comp rest with the switch enabled and battery out to reset cmos? I have heard anywhere from 10 sec to all night.

Thanks guys for your input and your time to help me out. I would not have believed the solution myself if I had not found it. I had to remove the battery and enable my cmos switch and leave the computer down for two hours. I was able to reboot my computer and get into device drivers and found the driver was corrupt .
I then went into the control panel and deleted the driver from viewsonic . Note I have had trouble before with their drivers so I should have known better. I then selected windows sp2 as my default driver and now everything is working fine. This is an older keyboard with a lot of functions but apparently the driver is not compatible with vista . Again thanks for your time and effort. I hope this may help others who may have had the same issue.
