error when startup HP TC t5720: Memory can't be read & o

[micheal]

Everytime when I start my HP TC T5720, I got those screen : the instruction at '0x77777d34' referenced the memory at '0x000000' can not be read.

Then after a second , it will come out another one stating : window cannot find the "idlist: number, Number' blah blah.

How to fix this problem?

Thanks,
