Computer freezing at BIOS after installing GTX 760

Hello,
Specs:
GTX 760 (from GTS 250), both EVGA - forgot to meniton that the 760 is 2g Superclocked edition.
Gigabyte Z77-DS3H motherboard
i7-3770k
Corsair VX550 watt
8gb ram
Windows 7 64-bit

I recently bought the GTX 760 for my rig. After placing it in my motherboard and booting up my computer, the start up was forzen at the BIOS-entry screen for about 10 minutes (I could not even enter the bios). I restarted the computer, and then it went down to a 2 minute start-up before hitting windows. I installed all the drivers for the 760, and reset my computer. During the restart, it again froze at the BIOS entry screen for about 2-5 minutes, and then loaded to the Windows login screen.

I removed the 760 and placed the GTS 250 (old card) into my rig and the same frozen screen happened, but for an even longer period of time, then I shut down my computer. I removed the 250 and replaced the 760 into a different PCIxe slot, which also had the 2-5 minute boot time. I reinstalled all the drivers, restarted, and again it took 2-5 minutes to boot. Everything appears fine, but I am afraid to restart/shutdown my computer to have a long boot time.

Sorry for the long explanation, I just want to know what to do - Did some research and the solution I keep getting is "flash the BIOS" - which I've never done. Any other solutions would be very helpful.

Thanks

Just one more thing, you're delete button does work right? :D

If it does, its the bios and heres an instruction guide on how to flash your bios:
http://www.gigabyte.com.au/webpage/20/HowToReflashBIOS.html

The Q-Flash portion is relevant to you since your board supports it and its the easiest method. Before that though, read over your instruction manual that came with the board and just make sure you're aware of how to revert to the default bios if something goes wrong. Gigabyte provide that your board has an emergency bios on their site but not actual instructions on how to use it. The chances are nothing will go wrong, but its a good precautionary measure to have available.

Also only the END key is necessary for QFlash

Thanks for the reply!!

I have, and triple-quadruple checked the connections after the first freeze.

And the solution does say to flash the mobo's BIOS. I've never gone into the bios except to change the boot drive, afraid to risk system failure because of that.

I've just never had a problem with the mobo before, so I thought there *may* be another solution.

Well the wattage of your PSU is more than sufficient and it wouldn't be the 760 since you didn't get a boot with your GTS250 either.
Given that you got a boot out of it after swapping into another PCI-E slot it definitely looks like its motherboard related. Does your first PCI-E slot have any signs of physical damage?

Also, given that you got up on the boot on the second PCI-E slot I'm hesitant to suggest that it might be the BIOS. Since you have a dual bios though and haven't really customised the first it might be worth reverting to the default bios and checking whether that helps your boot? Do you want me to explain how that might work?

No physical damage showing on the first PCI-E, not sure if it was loose or not, but the new slot did feel more secure.

If you could explain how to revert to the default bios that would be helpful. I only see 1 bios when booting though, and that's for the mobo.

Thanks again.

Yeah that would be expected, once you've used a PCI-E slot a few times its not as tight as originally, although if it feels overly lose that could be a problem.

The second bios isn't visible, its just there in case something goes wrong on the first. After reading up a bit more on your board, the second chip doesn't seem to do much, looks like a marketing gimmick.

There is a way to update the bios through Windows if you're interested but I'd advise against it since if something goes wrong in windows it'll corrupt your bios and you'll have no way of fixing it.

Have you restarted your computer since the last succesful boot?

If I am going to adjust the BIOS I'd rather do it the safest way possible! So if through windows is risky, I'd rather not.

No I have not restarted - should I do that now?

It would be useful, considering you got the first boot on the second PCI-E slot I'm kind of leaning towards your first PCI-E slot being damaged. Another succesful boot would go towards confirming that hypothesis.
I'm slightly concerned at what will happen if you cant boot back into windows though, will you have any way to reach back onto the forums?

Rebooted, was definitely faster 1-2 minute boot time. Still froze at the BIOS-entry screen and could not enter the BIOS menu, though.

When you say boot time, are we talking about windows boot time or just the bios initialisation time? Windows boot time is variable on updates and other background processes so I wouldn't worry about that.
When you try to enter the bios what happens? Does it just freeze?

Talking about total time. It's very quick to get to the initial "DEL to enter BIOS/Q-Flash" ... etc screen, but then it freezes there and does not allow me to enter it. That frozen part takes the most time, when windows boots, it's the same as usual, like you said.

When I try to enter the bios, nothing happens - I keep spamming the Delete key and it just stays frozen at the screen until it continues to windows, I can try rebooting and just spam the Delete key until something happens, and update you from there.

Thanks a lot for the quick replies llkashll!

Hmmm thats odd, can you verify that you're keyboard is working at the time when you're pressing delete? Easiest way to do this is probably by hitting caps lock and seeing whether the light turns on.

I'm not very convinced that its a corrupt bios since you're booting fine, but if we can get into it we can revert to fail safe defaults (in case a setting somehow got changed) or flash over it (I read up more and you have an emergency bios so its safe).

Both options are coniditional on you being able to get into the bios though...

Haha no problems man, I'm not busy at the moment so glad to help

Yup, the caps-lock works, I tried that too when resetting to make sure it wasn't the computer. Ill try to get into the BIOS again now, and will reply from another device to let you know, thanks!

First time I restarted - I spammed DEL for about 2 minutes straight during the initial bios screen, and that did not work. I actually ended up on a blank, black screen and the keyboard was unresponsive.

After a second reset, it froze on the same BIOS screen for about 1:30 mins, and then went into booting windows again where it took the usual 20 seconds.

Alright, I will try that.

I am going to pick yours as a solution, though I might try doing a reformat.

All of this will wait till tomorrow morning, as it's getting late for me. So I will let you know how all this works out tomorrow!

Thanks a lot for your help, Kash!

Updates:
I did not do a flash bios, however I removed the CMOS battery and waited 30 seconds and then replaced it, reset the computer and nothing.

I then removed the GTX760 and placed the GTS 250... and then it prompted me to reset the the BIOS to default settings and reboot! Which I did, and everything loaded faster now with the GTS 250. (within 30 seconds). I think I'm gonna try and update bios (still requires a flash) and place the GTX760 back in.

---

Bios was updated - and now the GTX760 works fine, and the load time is back to normal. Thanks a lot for the help!
