PC won't POST after installing liquid cooling

[adammitchell]

Hi everyone.

I'm having a really strange issue with my computer. I just bought a new MOBO, CPU and GPU and put it all together on Friday. I was working fine. Did some work and some gaming on it - no issues whatsoever. The only thing I wanted to go back to the store for was a liquid cooling system for my CPU. I bought a Corsair Hydro H55 and installed it, booted up my system and it worked great. I then shut down my computer because I noticed that I had left one of my chassis fans unplugged - no big deal.

I shut down the computer, plug the fan in and turn it back on only to see the following message: "Chassis intruded fatal error system halted."

Okay, so it turns out that I had taken one of the jumpers off one of the pins - again, no big deal. Found the pin lying in the bottom of the chassis, popped it back on, good to go.

I turn the computer back on and everything turns on - lights, fans, everything, but now the computer won't POST at all.

I've triple checked that everything is plugged in properly and nothing seems out of place. I don't really understand how it would boot fine and then completely go dark on me.

One further symptom that I have noticed is that the speakers make a very strange sound when I turn the computer off after unsuccessfully attempting to boot it. The closest thing I can compare the sound to is it sounds like someone is firing a laser gun in the speaker. Like a really cheesy sci-fi "pew" sound.

Any ideas?

My Build:
CPU: AMD FX6350 Vishera 6 core 3.9ghz
GPU: ASUS Radeon R9 390x STRIX 8GB
MOBO: ASUS M5A97 LE R2.0
PSU: LEPA MaxBron B1000-MB 1000W
HDD: WD Green 1 TB
PSU: Corsair Hydro H55

Please do a proper cmos reset
unplug PSU from the wall
pull out the CMOS battery on the MOBO
Hold the power button for 15 seconds very important
reinsert the cmos battery
plug in psu and boot up
let me know results.

Hi! Thanks so much for the response.

I followed the steps you posted, but I'm still getting the same issue. :/

Don't know if this helps at all, but it really seemed like the issue began when the jumper was removed from the pins. I had removed one jumper to plug in a fan and had removed during the process of trying to plug the fans in and forgot to put it back on.

I'm also posting the above images so that maybe you can see if somethign is not connected properly to the MOBO

This happens because you put the jumper to the wrong position. You installed it on the two right pins where you are clearing constantly the Real Time Clock (RTC) RAM in CMOS. Remove it from there and install it to the two left pins. Page 1-17 in your mobo manual.

As mentioned in the manual:
"Except when clearing the RTC RAM, never remove the cap on CLRTC jumper default
position. Removing the cap will cause system boot failure!"

As stated above I see it aswell, you have the jumper located on the 2 wrong pins, slide it over then cmos reset with the battery and it should boot up

You guys ROCK!!! Moved the jumper over and BOOM! It works great now. Thank you both so much!
