i5 760 Issues.

post #1 of 20
Thread Starter 
So, recently bought an i5 760 for an existing 1136 machine. However, now I don't get a signal to the monitor (from the GTX465 graphics card). My old processor was an i5 650, which has inbuilt graphics, and it worked fine with the 465's DVI sockets.

No idea what's going on, feeling a little bit like a dumbass.

i5 760, no OC.
P55-USB3 Gigabyte 1136 MB.
4gig DDR3 Corsair Dom RAM.
GTX465.

We've all been there! lol.

Anyways, have you tried resetting the CMOS? Also, you may need to make changes in the BIOS to switch the video output from the onboard to PCIe.

Oh, and WELCOME!

That would be 1156,and it is not a cpu problem.The 650 doesn't"work with dvi ports"It doesn't matter what cpu you have.

Right, so whatever advice Curious George has on the matter is entirely eclipsed by how much of a douchecanoe he is, which is a bit of a shame.

I'm just telling you what I'm seeing - 650 in, plug into GTX465, no worries. 760 in, plug into GTX465, no dice. 650 in, plug into GTX580, no worries. 760 in, plug into GTX580, no dice.

The processor is, logically, the problem here. With two different motherboards, two different power supplies, two different harddrives and two i5 760s, the one constant is the 760s hate my desire to look at shiny objects.

Overkill, how do you suggest I get into BIOS? Put the 650 back in so I get signal, change it, then change the processors back over and hope and pray?

LOL. Anyways....

That is how I would do it, but your mass mix-and-match troubleshooting effort has me second guessing it will work. It's worth a shot though.

Have you tried the CMOS reset yet?

Does it POST beep?

At work at the moment unfortunately - will CMOS reset when I get home.

Gonna try messing with BIOS first, mind you.

Alright, at home.

Swapped to 650, booted up for BIOS. Says PCI is active.

Swapped back to 760, no signal.

Reset CMOS, booted up with 760 - no signal.

Processor still appears to be the problem. I'd be interested to see what Curious George has to say about it all.

But given it was two processors, two motherboards, two monitors, 4 monitor signal cables, two power supplies, and two different graphics cards... I'm so confused as to what the problem is here. 2300 bucks well spent, evidently.

I would say try a bios update. While any Gigabyte P55 USB3 should read an i5-760..

If you have the same issues with 2 different i5-760's then you should contact gigabyte...

Clearing cmos should fix any minor issues, but I have swapped cpu's many times and rarely have needed to do that.
Some times if a board is released before a cpu is it may not have the correct code for it, bios updates fix that. But I dont see one single bios update on gigabytes site that lists cpu compatibility...

And if the 760's do not work in 2 separate motherboards that work with other cpu's I would have to say you have 2 bad cpu's..
Process of elimination...

Until you can get the cpu working in any motherboard I would have to guess its DOA...

I guess it's possible. It's just really odd to get two CPUs and have both DoA. I guess I'll order in a new 650 to get the other one to boot, and then send the 760s back in for the inevitable "Uh, there's nothing wrong with these. 50 bucks please."
