I have an issue with using my gpu, a gtx 750-phoc with my desktop, I am running windows 10 pro.
If I remove it and boot up, everything is working fine, I install it and it boot up won't get past the hp logo screen.
It was working before around 4 days ago. I read some posts here and tried using the turning on legacy and disabling the secure boot after I updated the bios successfully to v80.52.
Can anyone help ?

Welcome to the forum.
I am not an HP employee.
You should also uninstall the current graphics drivers before installing the 750. You need to drill down to the generic Windows graphics drivers.
Disabling Secure boot and enabling Legacy boot before installing the 750 should do the trick. But you have save changes and exit the BIOS. Then you must enter the confirmation code to complete this change.

Well, this is perplexing.
Your PC has the required 300 watt PSU. You are disabling Secure boot, enabling Legacy boot, and confirming the changes at next boot before you install the 750.
It seems, if I am understanding correctly, the PC will temporarily boot to the 750 but then you lose this functionality.
You have also verified the 750 works in a different PC.
It has to be something with the BIOS settings on the PC.
I have never seen this situation, after changing Secure boot, Legacy boot, and uninstalling the current graphics drivers, where the graphics card works and then does not work.
You said you tweaked some BIOS settings. What did you tweak?
Maybe try resetting CMOS (pull the MB battery for about 10 minutes), you might install a new CR2032 battery to be safe.
Then disable Secure boot, enable Legacy boot. Exit, save changes, and confirm using the confirmation code.
Try a different PSU. Maybe the card is pushing the factory PSU or the factory PSU is failing.

Hi there, I bought a new PSU of 500w the other day because I even got another gpu, a gtx 970 cause it was a great deal. It did the same thing, booted for the whole day and then just crashed randomly and now it won't even boot with either gpu just the onboard graphics.
Regarding what I tweaked in the BIOS, I only touched the legacy and secure boot part.
There are some some settings in the Bus Options tab with stuff like VGA Palette snooping which is Enabled by default and Pci SERR#(Not so sure if I remembered that correctly) but it is disabled by default.
Wanted some help about those as I have no idea what they do and didn't want to touch them first.

I cannot install the drivers as the pc cannot boot with them or it boots but I cannot see anything else apart from the hp logo of my monitor.
I have decided to tomorrow try and install windows 8.1 because the bios description was for windows 8.1 and I have windows 10.
I will give it a go and I will communicate further about the results though I have much reservation that it will do much to help my current situation.
Thank you again for your reply, much appreciated. I am off to bed now as tomorrow is a busy day for me.
