Ok I am so out dated it is nuts but I am poor so I build what I can. I just put together an old N2pap-lite machspeed mobo, with amd 2400 xp and a 120gig hdd. os is xp home at first I had 2 256 ddr ram 266 then I tried an upgrade to 2 512 memory card at pc3200u that i got from work and the computer started acting all tweeky. it wanted to keep sending error reports and shutting down programs. did I not do something right with the memory, because when I went back to the first configuration it went back to normal.

Sounds like the RAM is defective. Reinstall it & immediately test it with memtest86 or memtest86+. Test the sticks individually, then together...if any errors are found, replace it. http://www.memtest86.com/download.html http://www.memtest.org/ Also, with a socket A system, the CPU & RAM should be run at the same frequency for 1:1 ratio. The proper RAM for a 2400+ is PC2100 (DDR266). If you use PC3200 (DDR400), it's important to adjust the BIOS settings to run it at 133MHz frequency (266MHz DDR) to match the CPU.

Well I am not to good at BIOS setups and it seems to work good with PC2100 so I just need to find 1gig DDR at PC2100. Now will any of the NEW Graphics cards work on this particular motherboard and if so which ones? or will I have to find an older one? because i really want to upgrade that

Why would you waste your money on PC2100 when you already have 2 x 512MB PC3200? All you have to do is enter the BIOS & change a few settings...there's nothing to it. Just make sure "Host Clock at next Boot is" is set to 133MHz & "DRAM Clock at next Boot is" is also set to 133MHz - these are listed under the "Miscellaneous Control" menu. Also look under the "Advanced BIOS Features" menu & check the boot order: 1st boot device = floppy 2nd boot device = CD-ROM 3rd boot device = HDD-0 The next thing you need to do is download one of the memtest programs. If you have a floppy drive, I suggest you download the floppy disk package. The file you download will have to be unzipped, then click on install.bat & follow the instructions. If you don't have a floppy drive, you'll have to download the bootable CD ISO. You'll need the proper software to convert & burn the ISO. If you don't have a program such as Nero, I recommend ImgBurn...it's totally free & works well: http://www.filehippo.com/download_i... Once the floppy or CD is created, boot off it & let it run for at least one complete test series...it will take 30min or more to complete. If errors are found, consider the RAM to be defective, then try testing another stick. If both test good, install them together & test again. This is going to take at least a couple of hours altogether. BTW, if you don't have the motherboard manual, download it here: http://tower.tomsk.ru:8080/drivers/...
