Random BSOD and reboots

Hi,

I have been having my computer for only one week now, but it seems to have some difficulties. I get some random blue screens of death, when I have loaded Vista - it reboorts at works fine. First et was the memory, but it seems to been corrected.

I have installed all drivers from a cd, which I got from the company I bought my laptop, all though I have installede a mouse from Trust.

The BSOD are as:
