I bought a new sealed i7-4790K off of eBay, and switched out my old i5-4690K. Unfortunately, when I booted the computer up, despite all the fans and LEDs turning on, there seems to be no output to my monitor, keyboard, mouse, or speakers. After a few seconds it will reboot and remain like that.
Steps of install:
Once I booted up however there seemed to be no output to my connected devices despite the fans and LEDs coming on.
I reinstalled my old CPU and it works fine. In addition I tried these steps to correct the problem but none have worked so far:
Specs:
Motherboard - MSI Z97 Gaming 7
PSU - Corsair CX750M
CPU - i7-4790K
RAM - Corsair Vengeance 16GB
OS - Windows 8.1
GPUs - GTX 980 SLI
Does anyone have any ideas on what else I can try or is it just a DOA? Thanks.
Steps of install:
- Switched off power and unplugged PSU.
- Removed cooler (Hyper 212X Turbo).
- Cleaned off old thermal paste off of old CPU and cooler with rubbing alcohol.
- Switched the CPUs (it fit perfectly and is compatible with my motherboard [MSI Z97 Gaming 7]).
- Applied a rice sized drop of thermal paste to CPU.
- Secured cooler back onto CPU, tightening in the pattern shown in the manual.

I reinstalled my old CPU and it works fine. In addition I tried these steps to correct the problem but none have worked so far:
- Removed battery for 30 seconds and replaced it.
- Pushed the CMOS button on the back for 5 seconds.
- Updated to latest BIOS.
- Restored BIOS settings to optimal default.
- Plead and begged it to work.
- Switch the DisplayPort cable to the motherboard instead of graphics card.
- Removed and replaced RAM.
