Blue Screen Error (WHEA_UNCORRECTABLE_ERROR) After Thermal Paste Replacement on HP Victus

[Abzalxon]

Dear HP Support Team,

I am experiencing a critical issue with my HP Victus laptop. After powering it on, the system stays on for approximately 20 seconds before displaying a blue screen error with the stop code: WHEA_UNCORRECTABLE_ERROR. This occurs consistently on startup.

This issue began immediately after a technician replaced the thermal paste on the CPU/GPU using a standard (non-original) thermal paste. Since then, the laptop fails to boot into the operating system and shows the blue screen error every time—even on the second attempt.

I have attached a photo of the blue screen for reference.
Please advise on the possible cause and solution. Could this be related to improper thermal paste application or hardware damage?

Looking forward to your support.

Kind regards,
Abzalkhon Akramov.

@Abzalxon, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding WHEA_UNCORRECTABLE_ERROR After Thermal Paste Replacement! 

We're thrilled to have the opportunity to assist you and provide a solution.  

When experiencing a Blue Screen error with the code WHEA_UNCORRECTABLE_ERROR, especially after replacing thermal paste, it's crucial to identify potential causes related to hardware changes or adjustments that were recently made. Here's a step-by-step guide to help troubleshoot the issue:

Check Thermal Paste Application:

• Ensure that the thermal paste was applied correctly. Excessive or insufficient thermal paste can affect heat dissipation and potentially lead to overheating or hardware malfunction.

Verify Hardware Reassembly:

• Verify that all components, including the CPU and GPU, are properly seated and connected. Loose or improperly installed components can cause hardware errors.

Inspect for Physical Damage:

• Examine the motherboard, CPU socket, and contact pins for any physical damage that might have occurred during disassembly or reassembly.

Check Cooling System:

• Ensure that the cooling fans are connected and functioning correctly. Double-check that there are no obstructions blocking airflow.

Run Diagnostic Tests:

• Use the HP PC Hardware Diagnostics tool to run an extensive system test. This will help identify if any hardware components are failing (e.g., CPU, RAM).
• Instructions on how to perform these tests can be found here.

Reset BIOS:

• A BIOS reset to default settings may resolve issues that are related to incorrect hardware configurations.
• Instructions for resetting the BIOS can be found here.

Update System BIOS/Drivers:

• Verify that your BIOS and drivers are up-to-date. Outdated firmware or drivers can lead to system instability.
• Check the HP support website for the latest updates specific to your model.  

Hope this helps! 

Take care, and have an amazing day!
