Hi,
Iam not getting much joy either.
I logged it with HP and some idiot techie sent me basic instructions on booting with Safe mode and then said to run some hard disk tests -which may wipe the drive!
I think my problem gets worse (i.e. every 2 mins) as soon as I plug in a second monitor (HP L2208w). Its the same if I plug into a docking station or directly into the external monitor port.
I really need to use that second monitor too!
