Since this message I can switch it on but there is no display, no response.
I’m afraid I don’t understand this… what do you mean by “no display” exactly?
Can you see the Toshiba splash screen and can you access the BIOS properly?
From my understanding this BIOS should be set to default settings (in BIOS press F9 and F10 to save the changes) in order to get the same BIOS settings configured by Toshiba… then the BIOS should be configured properly.
Generally speaking the BSOD appears due to serious software or hardware problem.
In most cases the system recovery should solve system problems but if the BSOD would still appear even after the usage of recovery disk, then I would assume your hardware is affected.
This would mean that any single hardware parts like memory or motherboard should be tested
After that message, I have switched it OFF. When I tried to switch it ON the display stayed black but I could hear that the CPU Fan, HDD and the DVD Rom starts up. I can't see anything on the screen so I am unable to change any settings in BIOS. (When I first noticed this options in the BIOS I have tried to set it back to default but the BIOS froze). Any idea? Is it possible that only the BIOS is miss functioning?
