Computer booting (I think) but no display!!

post #1 of 16
Thread Starter 
Hi,
I gave my computer a clean today to get rid of all the dust. I cleaned it all, including taking out and disassembling the graphics card to clean it as well. I've put it all back together and it won't work. When I boot it up all the fan (except one fan) run, but the DRAM LED light turns on and stays red. There is no signal going to the monitor either. If I've missed any detail please let me know. I've tried turning it off and on again multiple times, pressing the Mem Ok button, but it won't work.

Computer specs below:

Motherboard: Asus P8Z77-M
CPU: Intel core i5 3570k
GPU: Galaxy Geforce GTX 670 2GB
PSU: Antec High Current Gamer 520w
RAM: Corsair Vengeance 2x4GB sticks. Blue with blue fins on top.
CPU Cooler: CoolerMaster Hyper 212 EVO
HDD: Seagate Barracuda 2TB
SSD: Sandisk Extreme 120GB

Did you remove the CPU and/or the RAM sticks from their sockets?

I had to remove a ram stick in order to take the graphics card out. But I put them back in after in the same places. I took them out after the computer wasn't working and put them back in again in case they weren't in properly. But it's still not working frown.gif

Are the sticks in slot A2 and B2 (blue)? That's the recommended alignment for dual channel.
Try to boot with one RAM stick in the A2 socket (left blue one) fist.

Here's a photo of the RAM slots and the RAM stick. They were both in the black slots, as seen in the photo. My computer was built by a computer company and the RAM came installed in the two black slots, so I've used those slots ever since.

The blue slots A2 and B2 are recommended by Asus for dual channel configuration.
Try to boot with one RAM stick in slot A2 first and install the second one afterwards if it works.
Also make sure the 8-pin EATX12V plug is connected (top left of the CPU).

The ram in the second picture does not look seated properly. It looks like the end without a movable lock is sticking out. When installing ram in these types of slots, Ive found you need to push that end in before setting the locking side end down.

Dude, thank you so much!! I've put both in the blue slots and it's working!

The only thing now is that the intake fan at the bottom of the computer isn't working. Any ideas why? I've checked the PSU cables.

Ok, thanks for your advice. I've put both sticks in the blue slots and the computer is working and it says in system information there is 8GB of RAM installed. So it should be fine now. Only thing now is the intake fan at the bottom of the computer isn't working.

Do you use a fan controller? I keep my fans on lowest settings and from time to time they don't get enough juice to start up. Tapping the fan or turning the speed up usually kicks them into gear.
