Game starts and immediately freezes my PC

[Cookie Monster]

Game seemed to be working fine till this morning, when I started it and it froze my PC. Twice. I have Panda Global Protection 2009 and disabled it; same problem. Closed any unnecesssary processes like WLM, iTunes 8 but it still has the same problem. Cleared all temp and cache files from my disk, uninstalled a couple of games to free up some space but the problem still persists. Can't see why this is happening though. If I try to run it in debug mode, it won't even start. My specs are:

Intel Pentium Dual Core T3200 @ 2.00GHz (32/64-bit CPU, SSE, SSE2, SSE3, SSSE3, EM64T, Intel SpeedStep, 2 Cores, 2 Threads, 667MHz FSB with 12x multiplier, 166.7MHz Bus Speed)
ATi Mobility Radeon HD3470 with 1.5GB VRAM (HyperMemory, Pixel Shader 4.0, Shader Model 4.0, Hardware Transform&Lighting, 400MHz Internal DAC, 500MHz GPU)
DirectX 10.1
Realtek High Definition Audio
Windows Vista Home Premium SP1 32-bit
3GB RAM (DDR2 @ 667MHz)
250GB HDD (Ultra ATA 133, partitioned into 1 116GB drive, 1 106GB drive and 1 10GB drive)
Motherboard: ASUS F5SL

Installed this to my C: partition that only has 2GB free of 116GB. Ran a virus scan but no viruses showed up. Ran Windows Update too, drivers up-to-date.
Nothing has been overclocked/downclocked ever. What may be the problem?

Uh, nevermind this, turns out it was some settings in Catalyst that were causing this problem :redface:
Still, pretty good summary of my specs, eh? :lol:

Glad you sorted it. :)
