Hey everyone. (Sorry if my english is bad, I'm a 15 year old boy from Denmark) Today i bought a h100i to cool my i7 3770k. I had to take out the motherboard to put on a backplate for the cpu, but when I put it all together again it didn't work. When I turned it on it beeped one long time, and two short times, which indicates that there's something wrong with the graphics card (I have a GTX Titan from Nvidia).

I've tried to take it out and put it back again, but the computer won't turn on. (When I press the "On" button on my case, the computer actually starts, but my screen doesn't show anything). If I pulled out my graphics card, and put the DVI cable into the motherboard UI, the computer would boot up in Windows just fine. So it really is the graphics card which has an error, but I don't know what's wrong. I've, as I said, tried to take it out, and put it back in - didn't work. I've tried to put it in the other PCI-slot - didn't work. I simply do not know what's wrong, and so I hope that some of you do.

Best regards, Chrissy.
 
Have you ensured the Titan is connected to its PSU power connectors and that they are firmly connected?

What PSU are you using? If your PSU was only slightly powerful enough to maintain your rig without the H100i it's very possible that it has been pushed over the line by supporting the hefty cooler associated with that system.

My PSU is an Energon 750 W, but I have no idea of what my system actually use.

I might be able to test the GPU in an other system in a few days, so I'll try that!

Big thanks for your help :)
 


Much appreciated.

Don't hesitate to return here when you have some leads. I learn by doing and am curious as to the actual cause.
