Hello decided to fix up one of my old computers...I am running an Asus A8n32-SLI deluxe and just my luck they have problems with sp3 install causing the reboot loop. Over the last few hours I have found out the following information:
The loop happens when I have my usb mouse plugged in, doesn't matter which spot and no other usb device causes. Have tried multiple types/brands of mice they all cause the loop. My flash drive also causes the loop but my keyboard does not.
When I reset the CMOS the loop did not occur until I sync'd my computers time, SP3 only
The loop only happens with sp3 installed
All intelppm's are set to (4)
If I hit f10 while the computer was booting up I could select what device I would like to boot from when I picked HDD the loop would not occur, changing the boot order to hdd as number 1 did nothing.
Clearly the issue is with sp3/mobo/usb
I am wanting to possibly try and sell this machine but it definitely won't happen if I cannot fix this issue.
There is a BIOS version/fix available at the online product page for the issue of the A8N32-SLI Deluxe not properly loading SP3. The issue you mention is well documented on the product page forum. When I contacted ASUS at the time of SP3 release with this problem, their support's solution was to use Vista 64 which I had installed by then without issue. I have since flashed the BIOS to version 1409 and successfully installed XP SP3 without issue.
See BIOS version 1409 which allowed me to load SP3. Click on download>BIOS version 1409:

Fix the system is unable to enter OS when USB flash drive is connected under Windows XP SP3.
Socket 939 has been discontinued for years and ASUS has stopped support for the board years ago. I still use mine everyday in a lab setting working with close up clinical digital photography. The AMD 4800X2 dual core still multitasks very well.
