HP ENVY Curved All-in-One 34-b1 - Screen turns Black / Buffer error after sleep

[_HiLdE_]

Dear Helper,

I bought my HP ENVY in November 2018 & since then, I encounter some problems:

1. Since a few weeks, my screen randomly turns black for some seconds & turns on again. Sometimes several times a day & sometimes not at all. The computer continues working.

2. When I  leave the computer for a long time (without going into sleep mode), it kind of blocks when I want it to start again, after moving the mouse. It does not do anything. After I press enter, it gives me a message on buffer stack. I just click on ok and the computer works again as normal. (see picture in Dutch - I did not find it in English). It starts with: svhost.exe - Systemerror - System detected an overrun of a stack-based buffer in this application...:

3. Every 4 seconds I hear a little tiny double click every 4 seconds on the left side (back) of the CPU. I only hear it when it is silent in my office. I have this since the beginning.

I have all latest Windows Updates.

System:

• Intel(R) Core(TM) i7-8700T CPU@2.4 GHz
• 16 GB
• Intel(R) UHD Graphics 630
• NVIDIA GeForce GTX 1050

I hope all these issues have a reason & I also hope they can be solved via this forum.

Thank you in advance for you help,

Hilde

Dear Asmita6658,

I did (almost) everything you requested:

Step 1 Windows Updates troubleshooter - No problems found

Step 2 Windows Updates - PC was updated

Step 3 HP Support Assistant Updates - Was ok

Step 4 Download and install the BIOS -  Was F.50 from 10/24/2018. I found a newer one (F.50 Rev A - 11/13/2018) & did the update as requested in HP Help. BUT the system information still gives me F.50 from 10/24/2018. So, not succeeded.

Step 5 HP PCs - Sleep and Hibernate Issues (Windows 10, 😎 - I did not do this since none of my problems were mentionned. So, not done.

RESULT:

Problems are not solved. Is it an idea to re-install Wndows 10?

Thank you, 

Hilde

Thanks for trying. Let's try re-installing the operating system. Back-up the data and the  try these steps -

1) Shutdown the computer. 
2) Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears. 
3) Press F11 once for System Recovery. 
4) Choose the Keyboard Layout. 
5) Click on Troubleshoot. 
6) Go to Recovery Manager and click on System Recovery. 
Note : Back-up all your data as System Recovery will delete everything that you had saved or installed on the computer.
