Question

X58 system not working, though it did just a second ago.

Oct 13, 2018 3:31AM PDT

Hello fellow forum members,

I'll start my thread with a little of a backstory.
I managed to grab a pretty reasonably priced P6X58D-E and i wanted to see how much better of a deal it is paired with X5650 compared to something like 2500k+overclocking board (since i got the x58 combo at the price of the Sandy Bridge combo).
I've done some benchmarks on my gf's 2500k system and proceeded to swap out the p67 pro3 for the P6X58D-E (changed just that). It booted into bios no problem, but after some time in windows it suddenly showed no signal. I uninstalled drivers in Safe mode (cause i was getting blackscreen after windows logo) but still no way to boot into windows. I swapped in a clean hard drive and installed windows from USB stick without a problem so i thought everything is all right now, but after some time after installing some programs and drivers the computer blackscreened again showing no signal on the monitor.
I pulled it out of the case thinking it may be causing some sort of short but since then it wouldnt post.

It only would appear to be running (fans spinning etc. though no signal) if i pulled out the 8pin CPU plug.

Everything still works fine if i plug it into p67 combo, so it cant be mobo/psu/ram/GPU related issue. Also tried plugging the combo into my personal psu with no success.

Got any ideas? What would be bust, the CPU or the motherboard?

Best regards,
Hubert

In single thread the 2500 wins.
In multi thread the x5650 wins.

When you swap the mobo you must reload the OS.
Then you hit the mobo maker's site and get the latest bios and drivers.....start with the chip set.

Make sure you don't leave any extra standoffs under the new mobo.

My main problem now is that the motherboard doesn't even start as shown in the first youtube video. I'm running it on cardboard so there should be no shorts.

The no start should be a hardware issue.

Unless you mean by no start where Windows is running. For that you often find you can't swap motherboards or CPUs without a fresh install.

In parting, this is where I always be sure the BIOS is current as well.
