toshiba c650 sat pro

[mtv1]

seems to be a common problem with these my daughter was on fb clicked a link the display went blue then blank most likely a coincidence ,when you boot up you get nothing blank screen no way of getting in to the bios , i've removed power the ram hardrive cosmos battery as i've seen it to be a fix , it works for a few mins then freezes back to blank any other ideas cheers

Usually down to overheating, although 5 minutes doesn't seem a long time. Much dust inside? Might also be worth running a RAM test (memtest of a linux live cd) on it.

have a feeling its the ram ok was upgraded to 4 gig from 2 might jus go back to 2g its fast enough for her what you use to test it ??

Same prodlem

I have been given a C650 laptop with the same symptoms.
The last time it worked it booted to Windows 7 and then froze.
On attempting to restart, a blank screen and no obvious sign of disc activity.
Holding F8 while powering up does not bring up the BIOS screen.
I believe milk was split on it.
