Installed new CPU Cooler, now computer turns on but no display

Hi Tomshardware!

I built my computer 12 months ago and went to pick up a CoolerMaster Gemin II S524 to install because I realized it had been running hot and loudly. I took off the original from the CPU, installed the new one, and after I had installed it completely with the thermal grease I realized I had to plug the fan in again. I fiddled around and finally got it plugged in, but had to painstakingly take out the RAM to be able to reach behind the cooler. I reseated the RAM again and plugged all of my components back in. On the initial startup it booted into Windows temporarily, but quickly BSOD and restarted. I waited, trying to get a look at what happened and it occurred again.

I reset BIOS, and tried to boot into Windows again but this time it went to the option screen where I pick if I want Safe Mode or Boot into Windows normally, but my Keyboard wasn't working. It sat there for a couple seconds while I tried to get power to the keyboard, and then it went to a screen with a small shape in the upper right hand corner about the size of a nickel but shaped somewhat like a block letter P.

Upon resetting the computer after this, the keyboard lights do not turn on, the mouse light does, and the HDMI powered monitor does not receive any signal. (I also tried to change it to my television to no avail) So I reset the CMOS, reseated my GPU, SATA cables, RAM (again), and other cables that I thought might be the issue with no luck.

The computer's specs:
ASRock 970 Extreme3 AM3+ Mobo
AMD FX-4300 CPU (at initial time of installation was OC'd to 4.2 but stock 3.8 as of now)
Gigabyte Radeon HD 7870 OC Edition 2GB GPU
8gb Corsair RAM, HyperX-Blu (or something close)
8gb G.Skill RAM, their budget type that came with my mobo for free


If there's any other information that might help resolve this issue it would be greatly appreciated. I've been reading through a bunch of different threads on this website and others but their troubleshooting help hasn't been what I need to get my rig running again.

Thanks for your time!

Did you happen to unplug the 8pin CPU power connector during this process? Make sure that's plugged in.

It was plugged in, and just to make sure I just reseated it and the same situation occurs

I also have tried to unplug the HDD / DVD drives to see if those were the issues

Check thats it's not a GPU issue, make sure the 2 6pins are plugged in. After this, if it still doesn't work, try it in a different slot. The best thing you can do here is isolate the problem, see what can't be the issue.

I've already unplugged the GPU power connections as well as reseated it in a different PCIe slot, and I just took out the Corsair ram and left the single stick in and the same problem occurred

What really stumps me if that you monitor cant even detect a signal. Generally this would either be a CPU or GPU problem. Check the HDMI cables, try other VGA, DVI, and seeing that you cleared CMOS, you'll probably need to flash the bios again. Other than that, this is very strange.

You can check different ram slots with each ram to check whether any particular ram/ ram slot is not working (or you are having issues with clearance due to cooler and ram is not seated properly).
You should follow following steps in sequence:
-check ram(with seperate slots and ram combination)
-check if video card is seated properly or is faulty(remove video card if u have onboard video)
-get your motherboard checked(after those 2 steps its 99% probability that the fault is with your motherboard)

Is it a possibility that the motherboard was somehow hit with static electricity? I don't really see myself building static electricity while standing on tile floor with rubber soled shoes and leaning my elbows onto the edges of my case though. I'll try and take off the back side of the case and see if any funny business is occurring on that end. Gah.

Highly unlikely, I would suggest checking if the CPU itself is placed correctly, reattach the cooler and work from there.

Took off and reinstalled the CPU cooler and everything is good! I think I used too much thermal compound, but sweet! Gah, glad it's taken care of. And thank you very much for your help ProWilma!
