As long as you won't be a victim of the AMD processor problem, it should be OK to install.
For the record, absolutely not an AMD problem; rather, a problem caused by OEM's (mostly HP) providing an Intel driver in their Window's OS image on AMD based machines. This driver was activated by SP3 causing the "endless restart" problem
Woops, didn't mean to imply it was AMD's fault- in fact I was going to say it was HP's fault- but that was going to be pure speculation.
As far as I understand it, the problem was as simple as a driver "INTELPPM" being installed on those machines. Apparently HP hadn't toggled a setting. everything worked for SP2, but I guess Microsoft fixed something for SP3, causing the problem.
not alot worked with SP3.
What do you mean by that exactly? I had a lot of software myself, and haven't encountered a problem with SP3.
