Screen and keyboard go on/off when gaming

[jameton]

Hi,

I've had this PC for more than a year, and it was working fine until recently. However, I started experiencing some issues while gaming. After running some tests, I can describe the following problem:

When the CPU or GPU temperature exceeds 70 degrees, the screen and keyboard start turning on and off, and Windows locks up, although the PC continues to run. For example, an online game remains active, and I can hear what's happening in the game as well as my friends on Discord. Then, things either return to normal, or it takes longer for the PC to cool down. The problem goes away if I manually set the fans to maximum, but I didn't have this issue before.

After that, I decided to change the thermal paste on the CPU and GPU, but now I have the same problem, except it starts at 80 degrees. I didn't change the white thermal paste, which is dry like plastic, on what I suppose is the VRM, because I'm not sure what it is.

So, I'm starting to think there might be a power-related issue, as even 90 degrees should be okay. I've never encountered a problem like this before.

Hi @jameton,

Welcome to The HP Support Community.  

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

I understand you’re dealing with a complex issue that could be related to several factors, including thermal management, power delivery, or hardware malfunction. 

Here are some steps you can take to diagnose and potentially resolve the problem:

Check Thermal Paste Application:

• Ensure that the thermal paste was applied correctly and evenly. An improper application can lead to overheating and thermal throttling. Since you mentioned the VRM thermal paste was not changed, it might be worth considering changing that as well, as it plays a critical role in cooling the power delivery components.

Verify Cooling System:

• Make sure that the cooling fans and heat sinks are properly seated and working efficiently. Dust accumulation can also impact cooling performance, so clean the fans and vents if necessary.

Update BIOS and Drivers:

• Check for any BIOS updates or drivers related to thermal management and power delivery. Sometimes, manufacturers release updates to address issues related to hardware management.

Power Supply Check:

• Inspect the power supply for any irregularities. A failing power supply can cause unstable power delivery, which might explain the on/off behavior. Ensure that all power connections are secure.

Temperature Monitoring:

• Use temperature monitoring software to keep an eye on CPU, GPU, and other component temperatures. This can help you determine if the temperatures are reaching unsafe levels before the system starts having issues.

Check Event Viewer:

• Look in Windows Event Viewer for any error messages or warnings that might give clues about what’s happening when the system locks up.

Test with Different Settings:

• Try lowering in-game graphics settings to see if the issue persists. This can help determine if the problem is related to GPU load or overheating.

Hardware Diagnostics: HP PCs - Testing for hardware failures

• Run any available hardware diagnostics tools provided by HP

I hope this helps. 

Take care and have a good day.

Hi, 
thank you for response.

I have tried everything what you said. UEFI diagnostics, diagnostics in windows etc. All HP tests passed.
The temprature is not going higher than 90 degrees. After many tests I can say that the problems starts when the CPU or GPU starting to work hard, while the temps is ok and fans working great.

I have also updated BIOS, then downgrated to the previos versions but nothing helped.

I really dont know what to do, I have no warranty since 04/05/2024 so I really depressed.

Could you tell me what thermal paste I should use for VRM? I could admit that this is not the same thermal paste that was on CPU and GPU, so I didn't change it. 

The same questions as here https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/I-have-a-question-about-VICTUS...

Hi @jameton,
 
Thank you for your response, 

When applying thermal paste to the Voltage Regulator Modules (VRMs), it's important to note that VRMs generally require a different type of thermal interface material compared to the CPU and GPU. The correct thermal solution for VRMs typically involves thermal pads rather than thermal paste.

I appreciate your efforts. As the issue persists, I am sorry to hear that I'm sending out a private message to assist you with the next course of action.
