Question about ASUS P4V8X-X Motherboard

1 Answer

Cannot start I am using an Asus P4V8X-X motherboard. This is the 1st time i am having this problem. The computer does not start. The lights does not even light up. The power supply is properly connected though. The monitor and mouse, which gets its power directly from the CPU is lighted up. The only thing is that the CPU cannot be turned on. There is a LED on the motherboard and it is lighted up when the power is turned on. Pls help me. Thanks.

Asus p4v8x-x bad bios checksum checking for floopy floppy not found checking for cd-rom start reading P4V8X-X.ROM could not find P4V8X-X.ROM

Hi, you can download the bios file here:

Please select your windows version.
Select bios and click on global for download.
You have to unzip the file before you install it.

You might have to change the cmos battery out with
a new one:

Thats why you get a bad bios checksum.
A reminder flashing the bios with a wrong one WILL destroy the mainboard.

This problem could be caused by a near flat BIOS battery. Replace the BIOS battery and go into the BIOS configuration and set the Date and Time etc.

P4v8x-x bios dont boot

your problem is in video card, try to remove and clean the connectors (bronze color) with an eraser. then re-install, if the problem still occurs try to hear beep (warning sound). we have different sound for the installed hardwares such as the memory card, video card and the boot sound. if you have installed an expansion video card remove this and use your on board video card to determine if the video card you installed is defective. and if you are using the on board video card install a new video card
