    Bizarre GPU/Mobo Issue.

    Really struggling to figure this one out.

    My main pc is a 2600k with a 1070 in it. Been working fine for 7 years, with just ssd+gpu upgrades. Really no performance issues at all, running 4.5ghz on air easy.

    Sooo I come to boot up last week and no display output, VGA error light is on the motherboard.... The cpu has onboard graphics... but my board does not have any display outputs on it, so I cannot test around that.

    Replug everything, it works. Day or two later. Same issue. Reseat card.. sort of boots. Not getting the instant power off when I try to switch it off so I tried a single monitor w/ different output and the hdmi works... boot to windows, install new drivers, plug in other outputs... everythings fine. Do some load testing, cpu maxxing around 70 under 100% load and gpu around 60.

    Wake up this morning and no fucking output again.......

    Try 1070 in another pc I have that's an i5 4670k

    Works no problem.

    Ok maybe my motherboard is fucked ? So I put the 280x from the i5 into my main build and it works..


    I'm very confused as to the root cause.... my guess is the 1070 zotac amp extreme is too heavy for the motherboard there's a slight GPU sag when it's in the 2600ks motherboard ( back in the day of puny gpus ), no sag in the i5.

    Any other guesses before I order an R7 1700+mobo+ram ? lol.

    Was gonna say maybe the 1070 is causing so much sag that the slot isn't working correctly 100% of the time. Or, it is just the mb slowing shitting out. Did you test the 1070 with Aida or any other stress test just to make sure it's not the gpu?

    Could be other things but it's more likely sag from the GPU. Had a similar issue with my old GTX460, it would weigh down the slot and occasionally I'd blackscreen and be unable to do much until I reseated it. Solved by throwing it in the trash and getting a 550Ti.

    That 460 could've been a sweet necklace. Shame on you for throwing it away.

    No amount of reseating will get the 1070 working in my main pc again at the mo. Popped the 280 back in and no problem.

    >.>

    Also tried the 2nd pciex16 on the mobo and nothing in that one either.... which seems weird.

    Well, the only logical answer is the Zotac is too EXTREME for your motherboard. Better sell it.
