Why won't my computer boot after installing my GTX 1050?

July 5, 2017 at 18:51:24
Specs: Windows 10
I have this pc (https://support.hp.com/us-en/document/c02838702) and I installed a Corsair CSM 550W power supply so I can upgrade the gpu. I bought an evga GTX 1050 (not ti) and after installing, the boot screen (with the hp logo) shows up, the computer beeps once, waits a couple seconds, beeps again, and is shortly followed by 3 beeps in rapid succession. When I replace it with my AMD Card, it boots up fine, even though I have no drivers installed. Please help so I can game again :(

I would suggest we check on the 4/6/8pins power connector to the motherboard as well.

That connector should locate near to the CPU processor and is used for the video system power supply purpose.

Hope this helps,

I doubled checked and it looks like all the power connectors (the 24pin and the 6pin) are connected. Do you think it's a problem with the card itself?

"That connector should locate near to the CPU processor and is used for the video system power supply purpose"

Actually, that plug supplies power to the CPU, not the graphics card. The GTX 1050, both plain vanilla & Ti, are very power efficient & get 100% of their power from the PCIe slot. No aux power connectors are required. It probably would have worked without a PSU upgrade.


The beep code indicates a hardware problem. I suspect the card wasn't fully seated in the slot.


Do you have another computer you can test it in to rule out the card as the problem?

I contacted an EVGA rep, and they told me that it was actually a UEFI conflict issue. For people with the same problems in the future, here is the response I received;

"We are sorry to hear that you are having issues your GPU. This sounds like a UEFI conflict issues. UEFI is a newer form of BIOS that new cards have. Earlier cards, like your AMD, were legacy supported cards.
If the motherboard does not support a UEFI VBIOS, then it will freeze on the BIOS boot screen (HP logo, beeps and then usually a white line blinks top left). Due to the age of your system, it is unlikely that one will work. However there are some things you can try to get one working.
The first thing you can try is to update the BIOS. HP might have released a new BIOS which added support UEFI cards. If that does not work, look for these settings in the BIOS:

With new HP computers either press F10 to get in the BIOS, or the Escape key to bring up the Startup Menu then select Computer Setup or BIOS Setup. There’s a menu on the Advanced mode side for “Security”. Under “Security” there will be a "Secure Boot Configuration" menu where you would want to disable both “Secure Boot” and “Fast Boot” and then enable “Legacy Boot Support”. When the options are set hit F10 to save and exit out of the BIOS Setup. The system will reboot and ask you to enter in a passcode to confirm changes. After the system boots into Windows go ahead and shut the system down and install the graphics card as normal. The graphics should now be displaying through the video card.

If a BIOs update does not work and you cannot find any of these settings in the BIOS, a UEFI is most likely incompatible with your motherboard.

There were no BIOS updates, and no settings available so I will be returning my 1050 and purchasing a 750ti, which from the reviews appears to be legacy supported. Thanks to pctestcard.com and riider for the quick responses :)
