So, i was helping my friend with his computer that has got a lot of trubles just after the waranty run off, when he play any game ex. Legue of legends (wich i think its not very graphics demandant) suddenly it will shut down, so i thought it might be something to do with the graphyc card or something ralated to temperature, so i enter de bios and in >Advanced > Primary Display >, and there are 2 options discrete and igfx, it was turned on Discrete, so i thought i should change to the onboard and enabled IGFX, after that save changes reboot and.... surprise no video signal .-. no even BIOS neither win or something, we try to conect it bvia the HDMI port to the tv but the same black screen, so i was wondering, should i try to reset the BIOS by the Hardware and if so, HOW?, or is there any other option. sorry for my bad english .-. & thanks

I would either short the CMOS jumper on the motehrboard...or remove the CMOS battery for a few minutes, then reinstall it...in an effort to force the CMOS back to default settings present when system was acquired.
