Black screen crash & restarts, no BSOD

Hi,

My laptop crashs quite regular, black screens and restarts randomly. I used to think it was heat related but the laptop doesn't really get hot. Idles at 38c.

There are no crash dump files at all, i've configured windows to not restart in the event of a crash and to generate a crash dump file. I've also installed a fresh install of windows 7 with only the manufactors drivers and windows updates.

I'm going to upload my system information with the hope that someone can shed some light on this.

System Spec:

Compal Cantiga
Windows 7 64 bit
Intel(R)Core 2 Duo CPU P8700 @ 2.53GHz
Motherboard KHLB2
4GB Ram
ATI Mobility Radeon HD 4650
Realtek HD Audio % ATI HDMI Audio
Built in Monitor (Genric display)
Hitachi HTS723225L9A360 ATA Device

Are you still having the issues after formatting? I don't see anything that pops out in your logs. However, I do see that there are a lot of failed Windows updates.

Try running the System Update Readiness Tool and see if it fixes the problem.

Once you've installed all the updates, you will need to update to SP1 - Learn how to install Windows 7 Service Pack 1 (SP1)

No, the drivers installed for the processor are the ones from mircosoft. The other drivers i have installed are the chipset drivers from intel that are from the manufacturers website.

Should i disable verifier.exe before doing these tests? or won't it affect them?

Thanks for your help

Yes. Disable driver verifier.
