So I'm helping my friend install some new parts, we installed a new motherboard processor and graphics card. Couldn't get it to start up figuring it was a driver thing we reformatted. All ran well Installed all the drivers, even tried out some games every thing was perfext . woke up this morning computer is frozen , restarted it and now the monitors won't respond every time ( still in standby) and also if I try to turn it off after I turn it on the power button even if held does nothing.. Please help. Thanks
