My PC do not detect any GPU

[EASosa15]

The system does not detect any dedicated GPU. Multiple fully functional graphics cards were tested in this system, and none of them are recognized by either the BIOS or Windows. The same GPUs work correctly in other computers. Software and driver issues have already been ruled out, which indicates a hardware failure in the motherboard or the PCIe slot.

I took the computer to the store where I purchased it (“Diunsa, La Ceiba, Atlántida, Honduras”) to request warranty service, but since I opened the PC (for obvious reasons), the warranty was voided. Even after explaining that without installing a GPU I would never have discovered the problem, no one took responsibility for the issue with the PC.

So, what could I do in this case? Should I just resign myself and assume that HP products are poor quality?

I need to use my PC. Please believe me when I say that I have exhausted all my options (I also contacted HP Customer Support and they did not resolve anything), and I need this PC for my work.

I hope you can help me.

@EASosa15,

Welcome to our HP Community forum!

I am genuinely sorry you're dealing with this -especially since you need this PC for work and have already done all the right troubleshooting. Based on what you've described, your conclusion is reasonable: if multiple known-good GPUs are not detected in BIOS or Windows, the most likely cause is a failed PCIe slot or motherboard fault. Unfortunately, that is not something software or drivers can fix.

This is understandably frustrating, and I want to be clear: a single defective motherboard does not mean HP products are generally poor quality. Hardware failures can occur with any brand. The real issue here is the lack of a satisfactory warranty resolution, which leaves you stuck with a system you cannot properly use.

Sometimes, in my opinion, HP retail partners apply warranty rules incorrectly or too rigidly, especially outside HP-owned service channels.

Since you are in Honduras, these are the best remaining official avenues you can try:

HP Support (Central America / Honduras)

• HP Support Portal (case creation, chat, escalation): https://support.hp.com

• HP Central America contact page (phone & online support): https://www.hp.com/country/lamerica_nsc_cnt_amer/es/contact/phone_assist.html

• HP Authorized Service Center locator: https://web-customer-care-pro.hp.com/lamerica_nsc_cnt_amer-es/help/service-center

When contacting HP, clearly state:

• The system never detected a GPU, even in BIOS

• Multiple graphics cards were tested and work in other PCs

• No physical damage was caused

• You are requesting motherboard or PCIe slot repair/replacement

If HP ultimately refuses warranty coverage, then realistically your only permanent fix is a motherboard replacement, through an authorized service center, a qualified local repair shop, or a used-source DIY replacement (eBay, etc.). Unfortunately, that would be the only way to resolve a dead PCIe slot.

You are not wrong to be frustrated -and you are not wrong in your technical assessment. I very much respect the thoroughness of your troubleshooting, and I'm sorry the process has been this difficult.

Kind Regards,
