Ok the events seem to be unrelated - its just when I boot the following driver fails to load 'i8042prt' which is to do with my keyboard and mouse ps2 port which I'm not using as mine are all usb. I actually don't get any critical events and the error events I have seem unrelated as above. I have a warning to do with SQLbrowser on boot up.
So specs are Intel Core Duo 2 E6600 2.4Ghz overclocked to 2.7Ghz, 2048MB RAM, Nvidia 8800 GTS 320MB, on board sound (Realtek High Definition Audio), a disabled EMU 0404 although I didn't have this until after I noticed media centre crashes, MSI Platinum P965, 2 WD Raptor 160MB drives in RAID 0 and 2 Seagate 320MB in RAID 1.
I run Vista x64 Home Premium (I think build 6000 - its authentic) with NVidia Forceware 163.69 drivers - I have no driver problems as far as device manager goes. If you need anymore info let me know - I've trauled all the forums I can find to little avail - thanks for your time.
