Question about DFI AK74-SC Motherboard
Subject: PC won't boot (BIOS error?

It never seems to start into the windows load, just displays:

same result. Then I left it on, went on to set up another PC to try to
some productive work. After several minutes, the unit started up
This happened another time, after letting the machine set off for several

company named Computer Peripherals Unlimited Inc.
I am running MS Windows XP Home Edition.

Thanks in advance, Bill Linhardt
Try clearing the cmos
<<<<< you will see in the picture a plastic jumper (in this case coloured green), move it to the other position and hit the on/off button, then put it back in its original position and power up the machine again. Hopefully the issue will have been sorted. If there is no jumper remove the battery for an hour and make sure the power cord is removed from the back before you clear the cmos
Good luck and thanks for using Fixya!!
