I also have a Toshiba Qosmio runing in Windows XP and I have exactely the same problem; the pc crashes almost as soon as I open a project in Premiere CS4. This problem disappears when I uninstall Quicktime.
Did you solve the problem by now?
Welcome to the forums.
Did you try the troubleshooting tips?
What version of Quicktime are you using? It must be a recent version - V7.55 works fine. When I first installed Premiere CS4 I had Qicktime V7.4 (I think) and had problems.
The version of Quicktime that I had (I unistalled now) was 22.214.171.124. I will
search for V7.55 (I leave a feedback if it works).

QT 7.4.x seemed to have a lot of issues with most things Adobe. For many, QT 7.5.5 seemed to fix them all, though a few are now starting to pop up. For some of these, the QT 7.6.2 version worked, but not for others. Not that long ago, I saw a link to older versions of QT for download. Had to be off of the Apple.com site, but when I went looking for it specifically, I could no longer find it - OE on my part, or maybe it was taken down?
Good luck and please report what works for you, as others will likely benefit.
I tried your "troubleshooting tips" and the links in that document take me to some Canadian kid's DJ video on youtube. hmm
Welcome to the forum.
Now, Eddie has not been active, and he was our "keeper of the Wiki." As I often link to the PrPro-Wiki Troubleshooting tips, I will check that link, and post back.
As for QT Player, the 7.4.x series seemed very bad for Adobe programs. The last "known good" version, in my tests, was 7.5.5. Jeff Bellune, a trusted source has stated that 7.6.6 seems quite good, after a batch of 7.6.x versions, that were death to Adobe. Were I a conspiracy theorist, I'd almost think that Apple did this with deliberation to sell more copies of FCP, but who's a conspiracy theorist... ?
