No output from graphics card but iGPU works, PCI-E lane fault?

post #1 of 3
Thread Starter 
Hi, I've got a weird problem as follows.

[Prologue]
I have a PC built in an Ace Ecco 250 with an i3 2100, Asus P8H61-M PRO, Kingston V200 128GB SSD, MSI 7850 OC 1GB, 8GB PNY 1333Mhz RAM and an XFX 450W Pro Core Edition PSU.

Now the PC was working completely fine, 30°C-50°C for CPU, 25°C-60°C for the GPU, everything at stock except the SATA setting was set to AHCI for the SSD.

[Problem]
However, after transporting the PC around 200 miles, the PC is no longer producing an output from the graphics card. As noted though, when I plug in my DVI monitor from the iGPU DVI port on the motherboard, it works completely fine. The GPU fan is on though but I checked device manager and it doesn't even seem to recognise that the GPU is there and it only shows the iGPU as the primary video device.

[Tried]
I've tried several things already which include:
1. Reseating the graphics card and making sure PCI-E power cable was in properly.
2. I've tested the 7850 1GB in another PC and it works completely fine.
3. I've tested a 5570 in the Asus P8H61-M PRO but it doesn't seem to output either, it's acting the same as the 7850 as it works in the PC it was in, but not here.
4. I've made sure the setting is set to use PCI-E first, over the iGPU, in the BIOS.

Are there any other possible solutions that I may have missed? The GPU seems to work fine, and the PC works fine without the GPU oddly enough. Is it possible for the PCI-E slot itself to be faulty?

Thanks!

EDIT: Just wanted to say that a rebuild and reseat of the CPU somehow cleared everything up!

You've gone through all of the steps I would have told you to go through already. The only thing that could be wrong is that the PCIe slot must have been damaged during transport which you can't really fix. You'll probably have to RMA the board which is a pain.

The only thing that I haven't tried is rebuilding out of the case, but being a small mATX case it's gonna take some time to take everything out. Guess I'll just try to build it outside of the case and see if I've any luck there as I've heard that the PCI-E lanes run directly off the CPU so perhaps reseating the CPU will help.

Haven't got the time to do that atm though after googling through what seems a ton of people having the same problem with no real solution to the problem. I wouldn't have thought that the graphics card would budge at all though as the 7850 is rather light and short and I screwed it in pretty good.

So basically,

[Further tests to do]
1. Try building PC outside of case.
2. Reseat CPU, check for possible damage to socket somehow?

Although Asus are usually pretty good with their RMAs, to RMA the motherboard I would have to send it the retailer and have them send it back to Asus from personal experience (I RMA'd a motherboard with Asus UK before and they wouldn't take a motherboard directly) and that took rather long which is why I'm reluctant to RMA.
