I have a Soyo P4VGA MB. When I purchased the board I made a huge mistake a nd installed only 256mg of DDR. Since then, I tryed to install a second stick of 256 DDR (same brand and specs) but the computer goes nutty. Crashes, freezes...etc. I pull the new ram, and it goes back to normal. I want to boost my ram to 1 gig (by putting a single stick of ram) but do not want to invest the money if the upgrade will not work. Any ideas?

even if the port is usb 2.0 is posible that the cable is not usb 2.0,

advice:

install chipset driver of mpther board and check whit other miniusb cable and see if is the same problem

best regards

After you reinstalled, you lost the drivers necessary for audio and network.
Visit this website, and reinstall the according drivers after selecting the windows xp operating system.

To get the bios you'll need to buy a bios chip from the net, im sure their are site flooding around if you google them. For installing a bios without a video card or a monitor connected. Im not sure if that would be easy. Or even possible if you dont have any certification as a professtional PC tech.

This sounds as though you inadvertently disconnected your video connector or knocked something slightly off on your motherboard. Please ensure all cards/components sit snuggly in their slots and verify all connections. The battery should not affect the system's operation, except for the system time, which in newer versions of Windows is set automatically.
Good luck!

Dear Sir,

*********** board is Asus old p4 Mother board.It supports maximum 1GB RAM of DDR 400(DDR1). According to your post your computer having only one 512 MB working RAM. If you want good purformance you can upgrade your computer by purchasing another 512MB DDR400 RAM and install it on another RAM slot.If your computer have only one working RAM slot,you can purchase 1GB DDR400 RAM & install it on older RAM place. I think it solves your problem.if you have any problem come back with more information. I will try to assist you more accurately.

good luck

Had problem like that.Removed board and isolated from touching anything metal.Plugged in memory and video card.Shorted power jumper and booted into bios setup.One of motherboard standoffs was in wrong position and shorting out mb.

Find the model name and google it, you should find a manual to help.
