Can't use computer without internet!

To put it simply, if I turn my computer on without the broadband internet turned on too, it will give the 'the system has recovered from a serious error message' and it won't go away, however much you click 'send' or 'dont send'.

Even if you DO turn it on, it will crash once or twice within the first minute of being on, then be stable after that. I made a post about it here;

I tried swapping RAM and it made no difference at all. I tried looking in the event viewer and I think this is the error it's showing:

'Error code 100000d1, parameter1 52fc8625, parameter2 00000002, parameter3 00000001, parameter4 ec39ba50.'

PLEASE can anyone give advice?? I am due to move house in afew days where there won't be internet so I HAVE to get this working. Thanks.
