New GPU computer wont boot

Anthony_88 · Apr 8, 2016

okay so last night i installed a gtx 970 that i got cause my other card broke and now when i start my computer it wont fully start unless i go into the bios and exit then it boots into windows. if i dont go into the bios the computer will act like it is shutting down like the monitors go black and my keyboard will stop working. and i have deleted all the old drivers and installed new ones so its not that i just really need some help thanks.

Try to start windows in safe mode and run a "driver clean up" tool. There were a couple that did a very good job for AMD and nVidia.

If that doesn't help you, then you might want to check power cables for the 970 and BIOS settings for the PCIe.

Cheers!

ok so shouls i have changed the power cables to the ones they gave in the 970 box ? cause im still using the ones my 770 used?

Power cables should be identical that said are you using Molex to PCIe adaptors? What PSU are you running?

Next download this:

And use it to delete all the GPU drivers. Then install the drivers again.

Anthony_88 :

Ok so then what do you mean about power cables that came with the 970? It may have come with 2 adaptors, but don't use those, only use the cables built into your PSU.

Anthony_88 · Apr 8, 2016

yea no it came with molex to pcie but i thought there was a way to use them but there isnt. so you think i should driver sweep again?

Anthony_88 :

First that, next does your computer have an integrated GPU? Did you ensure to disable it in the BIOS?

Anthony_88 · Apr 8, 2016

i wasnt sure how to disable it so i just deleted it. btw my mobo is the asus p8z77-v

Anthony_88 :

Yeah definitely clear all drivers and then go into the BIOS then to the Advanced menu, then to System Agent Configuration. In there select Graphics Configuration, then switch Primary Display to PCI Graphics (or PEG). Save that and reboot.

How old is this motherboard, your CMOS battery may be dying as well, if it doesn't hold this setting. Thats a cheap easy fix.

my mobo is probably like almost 3 years old and im pretty sure it doesnt save the setting in the bios when i change it to pci

Rogue Leader · Apr 8, 2016

If it doesn't save the setting (You're definitely picking "Save and Exit" right?) Then the battery may be dead.

Rogue Leader :

hey man i know its been a couple of days but i am just commenting to tell you that i had a windows update and it fixed the problem so yea thanks for the help anyway.

Anthony_88 :

Ah, good to know.

It is weird that a windows update fixed the issue. You sure it didn't install new drivers?

Cheers!

I agree, Glad it worked out but strange the way it did, I would think something else helped it along as well. Maybe it held the BIOS setting now too.
