Laptop sudden shut off!

[bodelekabir]

I have a laptop (Toshiba A200: core 2 duo, 1.73 ghz, 2gb ram, 32 bit). When I start my laptop, it sudden shut off after a couple of minute with a blink.
No technician is able to diagnose the problem. Please help me sort out this issue.

You might want to also try running some temp monitoring software and see what you get.
