Advent Roma 2000
Intel Celeron C900
Win 7 Home Premium
Intel Mobile 4 Series Graphics
I have removed the battery, held the power for 30 seconds and then connected just the mains and the problems remains.
I have removed the Heat Sink and cleaned out the dust and replaced
I have tried another RAM chip
I have tried another HDD
The only other thing I can think of is to remove the BIOS battery, but if anyone could please help then it would be greatly appreciated, many thanks in advance.
