Asus update in windows failed

[mylesb]

I have a homebuilt system with windows 7 64b home premium an Asus M4A785TD-M EVO motherboard that I was playing around with Asus update and it crashed in the middle of updating. The system reboots into windows but I don't have the green Asus load screen anymore and the f8 or del or any other functions work. I've cleared the cmos with the pins on the motherboard and all that did was set my computer to 2001. I'm very confused at this point and can't find any options on the internet. I've downloaded a new rom from Asus but I can't boot to either usb or a cd what next?

Can you get into the BIOS? If so rest date and time and see what happens

I can't get into the bios at all. I reset the time in windows so that's fixed but the bios is inaccessible.

PROBLEM SOLVED:
BIOS was ok the monitor was going black during post now I have to fgure out why but that's for another day,
