Are you receiving a prompt saying that the system time is wrong?

Something that may be saying, "Press F2 to enter setup" ?

Have you checked your memory?

Do you know how to reset the CMOS?

Look on your motherboard manual for a CMOS jumper or CMOS reset.

You will want to do this after a major change such as this.

I have had the same problem with a motherboard, but on contacting the manufacturer they recommended that I flash the bios to the newest version.

Is the motherboard an OEM motherboard or an aftermarket motherboard?

[best4earn]

Its after markeet not OEM

[Begginnerdev]

I would check with the manufacturer to see what your options are for flashing the bios.

BEWARE!!! If done improperly you can brick your motherboard.
