plugging in iPhone reboots computer?

Okay so ive unlocked my iphone as well as many others using the free unlock as paycay activation. well when i went to plug my phone in, to throw some songs and what not on, it totally reboots my computer (running windows xp) and it recovers and says a serious error occurred etc etc. Does anyone have any idea what is happening?

im running itunes 7.4.1 and my iphone FW is 1.02

ive uninstalled and reinstalled itunes already, but im hesitant to plug it in. so i thought id make this post first lol. any insight would be helpful. thanks!

C:\DOCUME~1\Peter\LOCALS~1\Temp\WER5db2.dir00\sysd ata.xml

those files are the ones involved in the error

they were in the temp folder. i cleared out the temp folder and am about to plug in the iphone again... here goes nothing

wish me luck =/
