I am running Windows 7 (32 Bit)

I started noticing the computer shutting down in the middle of working.
Now when I try to reboot in Normal Mode I get a message that says "unsupported Video Signal".
I can still boot in to Windows in Safe Mode.

Any ideas?

Thanks in advance for any help.

Unsupported Video Signal means that your video card cannot support the resolution you have set it at.

You can boot into safe mode because you are using standard 800 x 600 or 1024 x 768.

To fix it please set it up to the recommend resolution by your video card.

If you made no recent changes to your computer It probably shutting down to prevent it from overheating

Can you please provide us with video card name or model number and what is your resolution right now.

Hi - Just to add to advice from coxchris -
First 2 quick questions -
1. Are you running from a TV monitor ??
2. Is a Toshiba involved with this ??
These seem to be the 2 most related causes of the problem.
Click on a vavant area of the screen and from the Menu try to reset your Refresh rate and your Screen Resolution from Settings > Advanced

If the problem is related to either 1. or 2. this can fix or at least help it -

Thank You -

Thanks for getting back to me.

I am running a Toshiba 26SL 400U. That is a LED TV with a PC in option.
am also using a ATI Radeon HD 3400, which I installed in order to run dual monitors a while ago (dual 19" Benq FP731).
All worked well both with the dual monitors and with the single Toshiba for quite some time.

I have gone to a single 19 Monitor in order to use the computer as I get no Desktop with the Toshiba. When clicking on the desktop for resolution with the 19" I get a resolution of 1366x768 and it seems to be looking for a second display.

When in safe mode with the Toshiba I get a very different display menu with only about five or six options for resolution and the computer can not Identify the Brand and type of display.

Sorry I do not know what the recommended resolution is for the Toshiba.

Thanks to everyone. Problem solved. Uninstalling old driver and installing new display driver did the trick.

Again, many thanks for your help.Good Job.
