So everything in my old system worked fine (i5 4690k, gigabyte z97 SLI, gtx 970, 8gb gskill areas 1866mhz, Evga bronze 750w psu, multiple hard drives OS is on 850 Eva).

I ordered an i7 4790k and after the install the system no longer loads the bios. All the fans turn on and run at max rpm, all hard drives turnon ( I can tell because mech hdd starts spinning). My gpu lights turn on and the fans on that start to spin as well.

No lights on the front panel will turn on though. I even took the CPU cooler off and started the system with my fingers on the bare CPU to see if it generated heat ( it was only on for about 5 sec). Ice cold

Put in my old i5 and same issue, no bios all fans running no lights and no heat.

I probably fried the CPUs or Mobo because I'll admit I wasn't wearing an anti static wristband but my hand was on the case at all times while handling components.

Any ideas on what's wrong???

I already tried that by pulling th whole battery out for a minute, no luck. I did have some pretty big over locks on the CPU and ram for the old system though.

Did you just pull out the battery? Or did you pull the battery and change the position of the CLRTC jumper?

Had a quick look at your manual, I guess GigaByte uses only an two pin header system. The manual says to short the two pins with something metal for a few seconds. If you have a jumper, that would be ideal, but a screw driver would work.

There are capacitors connected to the power pins on the CMOS, these will maintain voltage on the CMOS for awhile after the battery is removed. According to your manual you have to short the CLR CMOS header pins together. Do this with the AC power unplugged. This procedure will definitely reset the CMOS.

Okay so I shorted the two pins with a screw driver and still no luck. I've got a friend bring his comp over in a bit and we will swap CPUs to see if it really is the motherboard

Congratulation on getting your system up and running. That's too bad about your GigaByte board. Things happen. Is your old board still under warranty? I wouldn't think it could be over 3 years old yet.

I've had issues with GigaByte boards in the past. Actually back in the P4 days. The first time the board failed, it was under warranty. They repaired it and sent it back, a year later, exactly the same failure (motherboard would overclock the RAM and make the system unstable) and it was out of warranty at that point. I've been with ASUS ever since. Of course this experience is anecdotal and I'm sure there are other users that could claim the opposite.

Again congratulations on getting your system back on it's feet.
