Sadly, those error reports are pretty useless! All you can really learn from them is that something has gone wrong - which you already knew.

Basically it tells you that two (or more) programs wanted to use the same chunk of memory at the same time, which isn't possible.

I've seen this happen after a change of video card, sound card, or other hardware change or addition - IRQ or DMA conflicts can cause this, and sometimes the hardware just isn't compatible with your chipset.

Go into 'Start', 'Settings', 'Control Panel' and 'System'. Select the 'Device Manager' tab, and look down the list to see if there are any little yellow triangles (with exclamation marks) against any devices.

If there are, we can progress from there...
