From blue screen, to gpu not detected, to no longer powering on

[Lycci]

Hello HP community,

I'm in a dire situation concerning my HP Omen laptop. 

While using it for gaming, the laptop tended to often freeze, crash to the desktop, and then blue screen to stop code: VIDEO_DXGKRNL_FATAL_ERROR. It happened more and more frequent as time went along. 

After it restarted it consistently gave an error message saying:

"Unsupported graphics card

There is a problem with your graphics card. Please ensure your card meets the minimum requirements and that you have the latest drivers installed".

And 

""An Nvidia graphics card was not detected in your system"

After checking the nvidia apps it seems to have removed all the drivers from the laptop and i was able to reinstall them. But sometimes it would just give a "failed" message.

There were also errors saying theres something wrong with the system state. So today I reset the entire system to default removing everything but it happened again and faster. It got to the point logging into my user was taking a very long time and sometimes failed to get to the desktop.  On top of that sometimes it would boot to the Bios saying the system needs to be repaired.

I monitored the heat and did a short stress test on the CPU  to see if it was overheating and while its normally around 70-80 degrees celcius, it now peaked a 99 briefly before dropping back to about 90 during the test. I quickly turned off the test and tried rebooting a few times. I managed to get to the desktop a few times before i had to turn it off and on again. Didnt get a chance to monitor the GPU as the main overheating thing was the CPU.

Only this time it shut down for the last time and wouldn't respond to anything anymore. No lights, no sound, no power, completely dead.

I have exhausted all the basic troubleshooting except removing the battery itself as it is built into it and attached to the motherboard. 

I still don't understand what caused these strange error messages and have no clue what was causing the issue as everything seemed to malfunction.

Did I completely fry an already overheated laptop? Is there any hope of it being repaired and if so, would it die shortly after anyway? What can I possibly do? I really need this device for work so I'm slightly panicked about it. All things seem like it's completely dead. 

Kind regards, 

Chris

Hi @Lycci,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

Your situation sounds frustrating, and it's understandable that you're panicked given the circumstances. Here's an organized breakdown of what might be going on and potential solutions.

Likely Causes:

• Overheating Damage:
  • The laptop's CPU reaching 99°C, even briefly, may have caused thermal damage to the motherboard, CPU, GPU, or other components.
• GPU Failure:
  • The NVIDIA GPU being undetectable and producing driver-related errors suggests a possible hardware failure in the graphics card or its connection to the motherboard.
• Power Issues:
  • Complete shutdown with no lights or power could indicate a failure in the power delivery system, possibly involving the battery, power ICs, or motherboard circuitry.

Steps to Troubleshoot Further:

(a) Check the Basics Again:

• Power Adapter: Ensure the power adapter is working correctly. Try using a known-working adapter compatible with the laptop.
• Reset the Battery:
  • Disconnect all external devices, hold the power button for 30 seconds, and plug in the charger without turning on the laptop. Then try powering it on.
• Inspect for Physical Damage:
  • Look for bulges, burns, or unusual smells that might indicate a failed internal component.

(b) Attempt a Hard Reset (if possible):

• Unplug the laptop, hold the power button for 15–30 seconds, plug it back in, and try powering it on.

(c) External Boot Attempt:

• If the laptop shows no signs of life, try booting from an external device (e.g., a Windows recovery USB). If the system doesn't respond, the motherboard may be damaged.

(d) Thermal Paste and Cleaning:

• Overheating could stem from degraded thermal paste or blocked vents. If you have experience opening laptops, you could clean and repaste the CPU and GPU. Otherwise, leave this to professionals.

Preventing Future Failures:

• Use a laptop cooling pad to reduce heat during gaming or heavy tasks.
• Regularly clean the fans and vents to prevent dust buildup.
• Monitor temperatures using tools like HWMonitor or MSI Afterburner to avoid overheating.
• Avoid pushing the system too hard if it’s not designed for intensive gaming.

I hope this helps.

Take care and have a good day.
