Vista white screen on startup

Vista white screen on startup
Ok - I installed SP1 just over a month ago and everything went well, no probs for a few days. Then I noticed that on startup at the point the welcome screen would usually fade into your desktop it faded into a plain white screen that would stay there for around a minute and a half, before then going to the desktop. So the machine is not crashing and you can access task manager but you still have to wait for the white screen to go before you can do anything else. Anyone got any ideas? My machine specs are below, and please - no 'vista is sh*te' etc comments (although requesting something like that is like a red rag to a bull!)

Mobo: ASUS P5E x48
CPU: Q6600 (not overclocked)
RAM: 2Gb Corsair XMS2 800MHz
GFX: BFG 8800GT OC2, running the latest drivers (released on 13th may)
OS: Vista 32bit
HDDs: 75Gb ED Raptor with Vista and a few games, 250Gb Seagate with everything else
PSU: Hyper TypeR Modular 580W

Cheers in advance for any advice!

Nice computer. I'm jealous. Evil or Very Mad

If the problem showed up days after installing SP1, it may not have anything to do with SP1.
Did you install anything recently?
I recommend you check all of your startup programs and disable the ones you don't recognize.
You can use this program:

When odd Windows problems crop up, reinstalling may fix it.
I had to reinstall Vista on my sister's computer a few weeks ago when her hardware acceleration stopped working out of nowhere.
I tried other things first of course (reinstalling drivers for one).
If you reinstall vista, all of your old data will be in C:\Windows.old by default.
