Built it last night started rite up perfectly no issues

Had to hit power button twice today to get it on

then did software today, installed windows 7 then did a windows 8 upgrade

Went into sleep mode (I think) and will not come back on after I restarted it

anyone have any suggestions? thank you

Have you checked that all power cables, and your CPU cooler are mounted properly? From the looks of it all your hardware is fine.
