Corrupt / Missing Windows Profile

If you think that things are going (relatively) well, they come right back at ya....
This time it's my laptop from work. I used to enjoy my HP NX8220 widescreen laptop. It served its purpose well over the last 3 years. Since it was out of warranty (and noisy), it had to be replaced by a Fujitsu Siemens Lifebook E8310.
Personally, I never liked the Fujitsu Lifebooks. They feel like cheap plastic laptops that might fall apart with every keystroke. Apart from the physical look and feel, there's the 'need' to use hardware which can only be used by installing a gazzilion Fujitsu installers/drivers (on the HP I only needed half the drivers to get a functioning laptop).
The quality of these drivers are questionable. On a default Windows XP Pro SP2 OS with ALL the tools/drivers recommended by Fujitsu the hardware and Windows OS don't seem to get along. Without any reason, the OS seems to hang every once in a while. And lately things have gotten worse....
