Closed CPU uprade + xp SP2 causes reboot loop Tags: Reboot Loop CPUs Windows XP Last response: January 27, 2012 8:02 PM in Windows XP Share Bud April 24, 2010 2:54:43 PM I replaced an old AMD CPU & M/B with a new 64-AMD & M/B combo, (Hardware is working fine). It was a drastic change for the OS to handle, and it caused a reboot loop, so I reloaded Win XP. No hassles really, all was well and the hardware & software were playing very nice, until…I installed SP2. Then it started into an endless reboot loop, again. Does anyone know a fix or work around for this. I would like to get to SP3, but first I need SP2. I’ve rolled the OS back to pre-SP2 install many times and tried some stuff, but no matter how I carve this turkey, it still ends up in a reboot loop when I get to an SP2 or SP3 installation. I ran into this a few years ago, and as I recall….my solution was to get a new HD and load Win XP clean. …But I’d really rather not reload all the software in this rig if I can help it.. So, do any of the gurus at Tom’s have a SP2 reboot-loop solution?
