UX1 crashing (BSOD) when zooming

[99Wakey99]

My first post, be gentle! I've had a problem or two with my UX1 straight out of the box. I pressed the zoom keys a couple of times and I get a Blue Screen of Death with the message APC_INDEX_MISMATCH. I found it particularly easy to reproduce the crash if Vista's "Tablet PC Input Panel" is onscreen at the time - zooming in or out results in a pulsing purple border to the window of the handwriting recognition panel and then the crash. Also Vista regularly reports that the Vaio Event Service has stopped working with an unexpected error.

I've filled in some comprehensive reports with Sony online and have completely recovered, restored and reconfigured the machine twice (ouch!) and they now conclude that the unit needs to be returned to be mended. I understand I may be without the PC for 5 to 15 days (is that right under warranty?).

Sometimes new and complex things are faulty but I wanted to know if anyone with a UX1 had experienced this problem as I'm loath to be without my PC (which I rely on) for 3 weeks to find that it's not faulty after all and that a driver or similar is at fault.

Have you tried using the latest INTEL (not Sony!) graphics adapter driver from Intel's website? As far as I remember, it is V 15.2. Try it, it may solve your problem.

The truth is: I always do a fresh install with my Vaio laptops, removing all those multimedia server/entertainment platform/etc. stuff. It eats up a lot of RAM and is a source for possible issues.

Try the Intel driver first, it may take care of your problem.

Hi P,

Thanks for the suggestion. I did try that Intel driver before the first rebuild but it still crashed in the same way. I went back in case I couldn't convince Sony of the problem whilst using a "non-approved" driver. The new driver allows the display to be rotated 4 ways instead of just the two, which was fun - it just still crashed!

Thanks again.
