Check it's not disabled in the BIOS and the drivers are correctly installed before doing something extreme like sticking it in an oven. It's not been turned off by the hotkeys by mistake has it ?

I've seen similar issues a few times, and almost always it has been right before a chipset/graphics controller failure, due to bad solder balls condition. If you are planning on a homemade repair I wouldn't recommend an oven "fix"/reflow. It is much better to use a heat gun and flux (no-clean flux).

But you should not start reflowing things on your board, before you are 100% that a bad chip connection with the motherboard is the problem.
