Solved PC won't restart, only a cold reboot works.

September 27, 2012 at 07:38:57
Specs: Windows 7, Core 2 Duo E7500/4GB
My computer won't restart, only a clean boot works.
When I restart it, it shows VideoCard info and freezes at Intel's screen, before the "BIOS settings" appear.
I've ran out of ideas, any help?


==SPECS==

Processor: Intel Core 2 Duo E7500
MoBo: Intel DG31PR
Video Card: POV GeForce 8400 GS 512MB
RAM: 4GB

Dual-boot (GRUB2) Win7 and Ubuntu Studio

Dual Monitor: Philips 215Vw (DVI) and LG 1753T (analog)

Thanks in advance

In light of this new information, check your boot order in your BIOS and make sure that the USB is not listed as a boot option. There also might be a setting for USB other than the boot order that will allow or disable booting from USB. If this is an option, disable it until you have a need for it.

You have to be a little bit crazy to keep you from going insane.

Post the brand and full model of the computer and if you have an add in video card, post the full model number of that.

If the computer is a custom built unit then post the model number of the power supply and any add in graphics.

Some motherboards and some psu's might cause this. The only way to test is to start by swapping psu.

This may also be an indication of esd damage somewhere. Basically some gate or collection of gate are not fully being reset on this restart.

Thanks for your responses. I didn't think it made a difference to say that I have two USB external HD's and by removing them, the problem went away.
Now I'll try to make it work with them.

Cheers

We don't know. You stated this,"My computer won't restart, only a clean boot works."

If you want to change the symptoms then provide all the facts you know or can see.
A usb normally won't stop a boot process. It may be possible that you set the usb to the first boot order and the system is now hanging. But that is not what you said in the first place. To get both of those facts to match up, I guess it could be some power leakage to the motherboard from the usb is keeping some part active.
It could also be a bad motherboard that is not fully resetting.

USB was listed as boot option, but when disabled, it didn't change the scene. As of now, I won't be able to test the "bad motherboard" or the "power leakage"

See also the hard drive boot order which should be a different place than the boot order.
