Hey guys, well i got a new evga 660 sc and inserted it into my pc, i disabled all the drivers for my old gpu and even disabled it....anyway when i boot my computer everythign looks like its working but..the screen is blank, normally i have to boot from my boot menu but this doesnt come up all i get is a blank screen....

Pc specs:

motherboard: asus m5a78l-m usb3
cpu: amd phenom II x4 3.4ghz
ram: corsair vengeance
psu: storm 600w
gpu: evga 660 sc


I understand that its not that detailed but any help would be amazing!
 
"I have disabled it"
does that mean you used i-gpu earlier or you have still not unplugged your old gpu from your mainboard?

also ensure that you completely uninstall your previous display drivers and not just simply disable it.
since you have no screen right now you have to unplug the 660 and return to the way it way before and than do as mentioned above.
you might also upgrade the mainboard BIOS first.

at the moment im using my old graphics card so that i can use my computer, how do i update the bios of the motherboard? im nearly 100% sure when i had the 660 in my rig all the old drivers were gone.
 
uninstall the current video card from the device manager. shut down. remove card. put new card in. make sure vga/dvi cable is hooked to video card. go into the BIOS on start up and disable the hybrid graphics. make sure the PEG or pci-e or auto is selected foe your video card. hit F10 and then ENTER to save. Machine will reboot.

Get to desktop?
 
open the booklet that came with your motherboard. all should be explained there as well as some pictures to help you along.

take your time, read stuff 10 times over before you do anything. pay attention to the bottom of the screen when in the BIOS... even if you screw something up you can clear the cmos ( also in the booklet ) or pull and replace the battery......... both of these should and will set machine back to "stock".

ask questions, lots if you must. there are people here that will TRY and help you.......... but we can't see what's on the screen in front of you........ makes doing stuff over the net hard sometimes.

i looked through my bios and could not find hybrid graphics nor could i find ]eg, my asus bios is most probably different to yours :(
 
when you were in the BIOS did you see anything that said "advanced".... up across the top?

if you click on that magic happens.

somewhere in the menus you might see something like onboard device config or peg link mode or any number of stuff you can click on to open up to get options. if you don't do this you
're stuck where you are.

there is something there. you just haven't found it yet.

If you have the OEM version of Windows, like one that came with a manufacturer computer, you won't be able to swap out major parts, as the OS thinks it is being loaded onto a different computer. Piracy-preventing, sorta.
Do you get the initial Windows splash?

Not necessarily. I tried replacing my old (proprietary) PSU in a Gateway with a Silencer MKII 750W, and it would only let me boot up into Safe Mode. Which is the sole reason I'm building a whole new comp instead of just replacing GPU and PSU
This is with Windows 7 by the way.
 
go into the TV's control panel and make sure the HDMI cable that is hooked to it is seen by the tv.

my "cable" is hooked to HDMI 1........... my computer is hooked to HDMI 4. So I make sure the TV is set to HDMI-4 when I run the pc on it.
