Get into the BIOS and check the temps as quickly as you can.
If the Motherboard was an issue, it wouldn't boot at all. I've been doing this stuff for a long time 
Peripherals will not cause this type of thing. |
Peripherals can cause this behavior, have seen it with defective network - ISDN - game and other cards.
Defective mainboard, CPU, memory or harddisk is also possible.

Take everything except the video card out and try to get into the BIOS.
If it does not shut off in the bios, boot from an other disk.
I have a computer business since 1985, seen a lot of strange problems. Finding what is wrong is a lot easier if you have parts to swap.
