AMd MObile 2400 with Asus A7N8X will not boot into windows

[Seizure]

Bought a brand new OEM AMD Mobile 2400+ from Newegg, and a Refurbished A7N8X from Newegg as well.

First oddity is when I boot up my machine is posts as "AMD Mobile Athlon 600 mhz". Which I thought was odd. So I went into my bios and fixed up my FSB and Multiplier settings. I put it at a modest 11x multi and 133 FSB with Auto Memory Timings because i have only Crucial PC2100 Ram. the CPU Idles at 86 degrees F so it's not heat. The Machine posts with those settings at 1463 Mhz. But when it looks like it is just about to show the windows xp splash screen it reboots. I've tried 12x 166, 10x 133, I even let it Auto and underclock itself. No matter what settings I use it will not boot into windows.

I have a ThermalTake Purepower 480w and the rails are steady so it's not a problem with juice. I even tried raising the Vcore up to 1.6v even though I'm not overclocking.

My only conclusion is either the AMD chip is defective or the Motherboard. If I would take a guess it might be the motherboard only because it was a refurb from Newegg and not the chip because I can stay in my bios for almost an hour without crashes. You guys have any tricks and tips I can try or any other suggestions?

did you just put the new mobo/cpu in a system that already had XP installed? your harddisk may have taken a poop and you made need to run a repair. although, last time that happened to me, i had a WD 120GB and it'd do the same thing. after the splash screen it'd reboot. i'd boot from the XP disc and go through all the shat, when i'd get to my partitions, it'd have my main partition with the OS installed labeled as UNKNOWN. Had to install on another hdd and just pull my data off. but who knows, if you have another socket-a processor, give it a whirl in there!

Have you tried doing a reinstall of Windows? Not a complete reinstall, but a reload...I forget what it's called.

Yes that is what I'm doing. I'm installing a new motherboard and chip unto an existing XP installation on a Maxtor 120gb 8 meg cache. My harddrives are recognized properly in the bios.

I guess I can try the XP boot disc thing, and I also have my old AMD 1.4 ghz lying around that the mobile 2400 was suppose to replace. Someone else on another forum mentioned that


"'ve had a refurb P4S533 board from newegg also, and it was prone to rebooting. If you're going to overclock, you have to go with the new stuff - the refurb is taking a chance. The Abit IC7-G I got from them has no problems being overclocked. I suspect the refurb stuff is equipment that others returned because it couldn't perform."


It might also be the newegg refurb.

Did you get the latest bios for the asus?

If you switch motherboards, you need to reinstall windows (especially with different chipsets), that is just how it goes. You can try a repair, but it is better to start off clean.

Yes it is the latest Bios 1007. Very odd. My roomate did the same exact upgrade form the same mobo, chip and processor (we bought our PC's together) and his went without a hitch.

If you have a spare HD lying around I'd pull the existing ones and install the spare and see if you can install Windows on it.

Ok Reinstalled. so far, and everything booted up. I am overclocking and testing my limits now.

For the voltage, i left it in the bios on Auto, and in windows Sandra and MBM5 says it's at 1.62. Kind of high for something that started at 1.4x volts right? I should put it back on manual and manually specify the voltage right?
