I recently put together a new system. I installed Windows 7 and the updates, the computer boots into Windows quickly and without issue. I updated the BIOS and it updated fine with no issues. Last night, I tried to access the BIOS to check out some settings and couldn't get in. At POST the screen is very clear to say hit the 'DEL' key to access the BIOS. I tried this several times on my PS/2 keyboard, and then tried a different PS/2 keyboard. I am unable to access the bios screen. I also tried mashing the 'F' keys to get access and couldn't get in. The system specs are as stated below. I am not sure if updating the bios caused the issue, or something else caused the problem. Assistance is greatly appreciated so I can determine whether or not this needs to be returned. Asus P8Z77-V Ivy i5 3570K 16GB RAM (2 x 8GB) Samsung SSD Many thanks.
