I am currently trying to fix one of my computers, it being a HP Pavilion p7-1109. My problem is with video output. This computers video out on its mobo isnt working any longer so I had to get a video card, the Asus Geforce GT 720, this is my second card that iv tried over the past week. So what happens is when I turn on the PC it goes to the HP logo and just stays at this point. I try to hit ESC as it says to do and a odd sound comes from my speaker (Mobo speaker) Iv been looking around for days trying to find a solution, but being unsuccessful I am now posting this. I currently have a Zotac Geforce GT 430 installed and the video works fine, but I cant use this as a permanent solution, so I hope someone can help me. Thank you.

hello,

 

   nice desktop!!

 

ok, when you first power up with the 720 installed, try tapping the f8 key repeatedly to get into boot options.  from there you shoud see the option safe mode. choose that one and you should boot up into a windows native low resolution display, then access the device manager and look for display adapter. this should enlighten you about how the PC is faring with the 720 installed.

 

i will put up the link to your PC for future reference.

this very well could be a motherboard driver conflict, if the 430 is doing ok but the 720 is mismatched. the socket 1155 i3 and the 430 are from a few generations back while the 720 is current generation. so the motherboard drivers enter the arena as your motherboard is handling the older i3  communicating with your new 720.

 

 

here is the HP support page for your PC model

and here is the nvidia support page for the 720...

ooops, forgot to ask...what windows version are you using? the PC model home page indicates win7.

ok, i have seen this configuration before, the 720 will need the oldest whql driver you can find for windows 10.... then install the driver  with a clean install, and you will see a green icon in your system tray, that is the geforce experience running in the background and that will use your net connection to sniff out the suitable driver for the 720. it is a whopper file size though, about 280 MB so it might take a while

do this while in safe mode with networking

i am not sure what you mean by clean install windows...but before when i saw this, that is what the user did and it worked, but it was with windows 8.1, so it shouldn't be much different with windows 10. he installed the oldest driver available and then let the geforce experience take it from there, all while booting into the safe mode with networking (f8 ikey mmediately after power up)

But the thing is I cant get past the HP splash screen. It literally freezes on that screen, I cant even hit esc for the boot menu (or whatever it says) it just sits and does nothing. So I cant put PC into safe mode as (I assume) the PC fails POST, and then locks up.

but with the 430 installed it boots up?

 

apologies, your unit uses the esc key for the boot options->safe mode...,  most of the time, it is f8

That is correct. The thing is iv tried two different GPUS, the 720 being the second to fail. I cant find anything to explain what is happening.

ok, i am going to suggest a bios reset now, i thought the 430 was enabling boot-up.

 

looking up the mobo now, it is kind of an intricate procedure, but the simplest way to do it is to remove the CMOS battery located in the motherboard and leave it out for a while. and then pushing and holding the power button for a few seconds to release the capacitance energy while it is turned off without the battery and then putting the battery back in and powering on.. the battery is the button cell type, usually cr-2032

 

after that, if you get a message suggesting the checksum error, boot into set-up to set the clock etc, that means it was successful

 

it is kind of a basic approach,and  it is befuddling how effective it is...

So heres the thing, since iv had the issue iv cleared cmos and done a bios upgrade (which probably did nothing as its for windows 7). So how would i go about doing this? 

 

Oh i just looked it up and im guessing that iv done this when clearing cmos.

On the mobo os the p7-1109 i see 2 things that could be, one says CMOS+PW and the other is FLASH_OVERRIDE which looks more like the traditional cmos clear. The one i did was CMOS+PW (which has 4 pins[2 side by side]), are these the right pins?

oik, here is the mobo link so we have a quick link for future reference

 

http://support.hp.com/us-en/document/c02980014

 

safe mode and bios access are tools available for a scenario like this one, i have to ask about your keyboard,,,that might be why the esc key isn't working at start up.

 

i see there are no ps/2 keyboard/mouse  ports. on your motherboard..... that hosed me up one time many years ago, usb wasn't working for keyboard.at start up

 

 

ok, there are links on the motherboard page for the cmos clear function under "Motherboard Layout".

Well i think i found my answer, i was asking around on HP forums and someone said the Geforce GT 7** series isnt compatible with the IPISB-CU (Carmel2) motherboard inside my computer. So I was told to go find a gpu i liked and ask the manufacturer if it is supported with the IPISB-CU (Carmel2) or ask on the forum.
