Computer lock ups

Ever since 1.11 SL has been locking up my computer completely to the point where I have to manual restart. It wasn't as bad as 1.11 but with 1.12 it's three to four times worse. Just with in the last 20 minutes I got three lock ups in a row. Not to mention at least 10 lock ups total since 12AM SLT today. Anyone else getting this problem? Here are my specs:

CPU: AMD Athlon(tm) XP 2200+ (1793 Mhz)
Memory: 1024 MB
OS Version: Microsoft Windows XP Service Pack 2 (Build 2600)
Graphics Card Vendor: ATI Technologies Inc.
Graphics Card: RADEON 9600 XT x86/MMX/3DNow!/SSE
OpenGL Version: 2.0.6012 WinXP Release

Hi Gin,
Got the exact same problem, and almost identical specs, except mine is a 9600 Pro card.

Personally I think it is the Catalyst driver that causes it, as it mostly seems to happen as I turn, and it has to render a new perspective. Or I zoom in to look at something.
Also suspect them, as I had an older version (Dec last year) when I got back online 3 weeks ago (after being offline 4 months), and did not have the problem then. After I updated the drivers, I have locked up consistently.

Hm, interesting...You know where I can download the drivers you have?
