Asus Q87M-E/CSM mobo led light on but system will not display

-1

Specs: Asus Q87M-E/CSM

EVGA 450 BT- PSU

Intel i5-4430 3GHz Quad-Core

Cool Master MasterBox E300L MATX Tower

16GB DDR3 RAM

Cdrom drive <-- HP TS-H65**

Seagate ST3100054***

Current problem: Minitower can turn on, but leaving it off for 5 minutes or rebooting the rig will cause it not to turn back on; led light will turn on but system won't. Basically, it will stay on and slowly fade away, even if I hold down the power button. I can't boot up my os, which was windows 7 home-premium and linux mint 17, because I got this error: 0x0000007E. I haven't looked to see if the Optical drive and seagate HDD are supported or need the firmware to be updated; the hdd and optical drive were pulled out of an 2008 hp-compaq minitower.

Nvm, it stopped working after i unplugged the cmos battery and plugged it back in. I’m going to contact asus or have a professional look at it. I troubledshooted enough already.
