Input string was not in a correct format error from .net framework

Hi,

Can someone pls advise me how to get rid of the following error message

which appears every time when I plug in or unplug the comp and at start-up

when it is unplugged. I am just a regular user of Sony Vaio VGN-TZ150N with

Win Vista Business and Sony help directs me to Microsoft and Microsoft to

Sony and so on... so I'd appreciate help so I can start enjoying using my

brand new computer finally:)

"See the end of this message for details on invoking

just-in-time (JIT) debugging instead of this dialog box.
