Installed h100 CPU Cooler, now PC Dead?

post #1 of 3
Thread Starter 
Hey OCN! I purchased a Corsair H100i V2 CPU Cooler to go with my i7 6700k.
When I was trying to install the CPU Cooler backplate on my Cooler Master HAF X case - the rear panel was covering two bolt holes on the backing plate; so I tried to carefully squeeze in the backing plate (without removing the motherboard) & I do believe I scratched the back of my mobo directly behind the CPU socket. I will try to post pictures later.

After seeing the scratch I pulled the motherboard out & attached the backplate with ease (Damn you, Corsair HAF X case!) - Everything else with the install with smooth. I did a little wire management then proceeded to try and boot - After hooking everything up, My PC will boot up normally with all LEDs working, fans, GPU, etc... however, my monitor is not getting any HDMI signal - I am not sure why?

I have a MSI Z170A GAMING M7 motherboard which has 3 LED indicators on it for VGA, DRAM, & CPU to detect a fail or bad connection; the LED light is constantly blinking on my DRAM, it is also blinking every 3 seconds on the CPU LED indicator. Does this mean my RAM and CPU are failing? Why will my monitor not get any signal? I tried booting from my windows 10 CD and still getting no signal.

I come to you once again, OCN! Thanks again for any information. I will post more on the thread when I get home from work. thumb.gif

Ignore the flashing lights for now. You want to focus on the LED display panel.

The M7 has an LED number display panel at the bottom that will display numbers and error codes like [A6] or whatever... What code does it end up showing? Number and letter like [A9] or board temp readings like [29] [28] [30]?

If your board is hanging at [A6] or [A9], you can try F1 to enter BIOS or Alt-L to use last known good BIOS setting and you might get your screen back.

If it settles to showing your board temps, you're in Windows without video.

For some reason, when you make changes to your system, the M7 BIOS will revert to using the IGP HDMI or Display Port outputs on the motherboard instead of your GPU. Plug your monitor into those and see if you can reach the BIOS on boot. If that doesn't work, you'll need to remove your GPU and then boot to IGP to reach the BIOS. Then you can reinsert your card, and all will be well unless you've rebooted enough to trash Windows. Then, you may have to rebuild Windows...

I don't know why MSI boards do this, but I'm damned tired of it, myself. sozo.gif

Wow! That is some intense stuff there. I will have to try that when I get home and post back.
