Normal Troubleshooting being:

1- Check all power cables
2- Check Dimm, GPU, CPU mounts, including Heatsink mounts
3- Check PSU is functioning correctly ( PSU Tester comes in handy)
4- Remove sata cables, peripherals and all but one mem dimm
5- Clear cmos
6- Cycle thru mem dimms, tryin each at least once, clear cmos in between each.
7- Try one dimm in slot closest and then slot furthest from Motherboard, then center slots
8- Remove power from the board, unseat CPU from socket, press power button, clear cmos, replace cpu, single dimm, no gpu, power on.
9- Same as above, but leave no mem sticks in dimms.
10- Same as above, Mem and GPU installed.
11- Still no luck? grab a spare processor from a buddy if available. Last ditch try.
12- Note behaviors and post codes thru-out troubleshooting process.
13- Still not working? Of course not nutterz, this is number 13 in the process and its doesnt mean "Happy Days"
