PC crashes/restarts constantly without warning, and no blue screen/error code

[H3b3--__]

Victus gaming laptop, will either freeze, restart, crash without any noticeable cause or pattern. Will do so dozens of times per day. I have re-install Windows 3 times, I have reformatted it 3 times, I have taken it to a repair shop, and I have re-downloaded everything. Nothing has made any difference. The repair shop updated the graphics card, updated the bios, and re-download windoes for a 4th time. It is about 1.5 years old, and I have been having this issue for about 5 months, and the issue has suddenly gotten much worse about 2 months ago. Seems like a product defect at this point, not really sure what else I should do.

Hi @H3b3--__,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding PC crashing and restarting!  

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

It sounds incredibly frustrating to deal with constant crashes and restarts, especially after multiple reinstalls and even taking it to a repair shop. Since there’s no error code or blue screen, the issue could be hardware related. Here are some things you can try:

1. Check for Overheating

• Monitor Temps: Use HWMonitor or CoreTemp to check CPU/GPU temps. If they exceed 90°C, your laptop may be overheating.
• Clean the Vents: Dust buildup can cause overheating. Try using compressed air to clean the vents.
• Undervolt the CPU/GPU: You can try ThrottleStop or MSI Afterburner to lower power consumption slightly and reduce overheating.

2. Run Hardware Diagnostics

• HP Built-in Diagnostics:
  1. Turn off the laptop.
  2. Press F2 repeatedly when turning it on to enter the HP Diagnostic menu.
  3. Run a Full System Test to check for RAM, SSD, CPU, and GPU failures.
• MemTest86: If the crashes happen randomly, faulty RAM could be the issue. Running MemTest86 overnight can help detect errors.

3. Check the Power Supply & Battery

• Use a Different Charger: A failing charger or battery can cause unexpected shutdowns.
• Remove the Battery (if removable): Try running it on AC power only to see if the issue persists.

4. Check Event Viewer for Clues

• Open Event Viewer (Win + X → Event Viewer).
• Go to Windows Logs → System and look for Critical Errors around the time of the crash.
• If you see Kernel-Power Event 41, it usually points to power issues or overheating.

5. Test the SSD

• A failing SSD can cause freezing and random reboots.
• Use CrystalDiskInfo or HP SSD Check to check the drive health.

6. Check for VRM or GPU Issues

• If the laptop crashes under load (like gaming), the VRMs (voltage regulation modules) could be failing.
• Underclocking the GPU slightly in MSI Afterburner can help diagnose this.
