Random crashes, black screen with white pixelations, not possible to restart, blinking power button

[Henrik_Salmen]

Hi, about 5 days ago my laptop began to randomly crash seemingly out of nowhere. Each crash results in a black screen with large white pixelations rapidly flashing in a seemingly random pattern:

During each crash the laptop becomes unresponsive and these squares flash for around 10-20 seconds before it shuts off and attempts to restart. Sometimes the 3.2 blinking code appears on the left hand caps lock key during restart, sometimes it powers on for ~1.5 seconds before shutting off again. After that, its not possible anymore to restart the laptop for several hours and when I try to start the computer the power button just blinks slowly in white colour. Not even possible to hard reset and try again to restart...

So far I've tried cleaning the inside, removing the battery, reseating the memory, and using windows diagnostics (both the memory and hardware diagnostics appear to come up with no issue, but an extensive diagnostic from boot inevitably crashes ~25-30% of the way in with the aforementioned symptoms). The only interesting change was that after battery removal the Cmos checksum error began to appear but other than that everything else remained the same.

Thank you very much for your help!

Hi @Kuroi_Kenshi,

thank you for your quick response.

I have an HP Pavilion - 14-ce0101ng Laptop.

Lately I ordered a new RAM and I installed it this evening. On the first look, it looks like it works all normally now and the computer boots again. I currently run some stress tests and when they are successful I want to reset the software and install Windows again.

I will let you know if it works and contact you if not.

Best,

Henrik

Hi @Henrik_Salmen,

Thank you for the response.

Try these steps:

Update Graphics Drivers: Outdated or corrupted graphics drivers can cause display issues. Visit the HP Support Website HP Support to find and install the latest drivers for your laptop model.

Check for Overheating: Overheating can lead to system crashes. Ensure your laptop's vents are not obstructed and that it is placed on a flat, hard surface to allow proper airflow. Use compressed air to clean out any dust build-up in the vents.

Run Hardware Diagnostics: Use the built-in HP Hardware Diagnostics tool to check for hardware issues. Restart your laptop and repeatedly press the "Esc" key until the Startup Menu opens. Then, press "F2" to run System Diagnostics.

Check for System Updates: Ensure your laptop's operating system is fully updated. Go to the settings menu and look for system updates or use the HP Support Assistant for any pending updates.

Test with External Display: Connect your laptop to an external monitor. If the issue doesn't occur on the external monitor, the problem may be with your laptop's display hardware.

Safe Mode Boot: Boot your laptop in Safe Mode to see if the problem persists. If not, the issue might be related to incompatible software or drivers running in normal mode.

Reset Laptop: If possible, try resetting your laptop's settings to factory default. Make sure to back up your important data before performing any reset.

I hope this helps.

Hi again,

Thanks for your advices.

So, I tried everything now.

I updated every driver and Windows. There was no overheating. I ran Hardware diagnostics with the HP Tool and with opcc, but no errors found.

The new RAM I bought didn't change anything. I tried to boot in safe mode or to reset the whole software, but it failed due to the crashes after a few minutes.

I got the advice from a friend that it could be a cable from the monitor, which is broken and indicates the graphic errors and crashes...

Could that be possible? And is it possible to repair something like that?

Best,

Henrik
