Hello, My Asus P4P800 SE motherboard has stopped recognizing my monitor LG Flatron 22'' . I have 2 PCs connected by a KVM switch. When I boot machine A, the monitor stays black. When I put the video card in machine B it works. VisionTec 1500 video card. OS = Windows XP pro. Can you help?

Hello you can find drivers and the manual here:

http://support.asus.com/Download.aspx?SLanguage=en&m=P4P800%20SE&p=1&s=15

You just have to select your windows system.

Any file from here needs to be unziped, before you install the driver.

Good luck

Hello download the manual here:

http://www.asus.com/Motherboards/Intel_Socket_478/P4P800_SE/#download

Please select your windows system

Open the manual folder and click on global for download

Unzip the file and you need adobe reader to read the content

Take a look in the BIOS and under advanced you should be able to see the motherboard settings for the drives. Make sure that the board is set to use ENHANCED settings and not LEGACY, then go to the BOOT section and make sure the SATA drive is the first drive.

Good luck

its a virus problem please again full hard disk format...........

some bios are able to boot with the (f12) key and then you pick which device you wish to boot with otherwise you must enter the bios and set the first boot device to boot your usb

Here is a link to Asus' Qualified Vendor List of RAM modules for your motherboard. I do not see it mention high density RAM. You would need to search the specs on the modules recommended to be sure.

ASUS QVL

In case you don't have the manual, here is a link for it too:

ASUS P4P800 Deluxe Manual

Memory info begins on Page 2-10. Again, there is no mantion of HD modules.

remove the external display card boot ur machine with on board then disable the on board display and then install your external display card and then connect it to the monitor

No. Your board can support any AGP video card.
But it does not support any PCI-E cards.
