Screen Flicker issue in DELL 5570

Hi There,

I would like to bring to your attention a recurring pattern concerning a screen flickering issue I have encountered with my laptop. Specifically, I have observed that when I leave my laptop shut down for an extended period of time and subsequently power it on, it operates smoothly without any flickering for a few hours. However, after this initial period of stability, the flickering problem resurfaces.

To illustrate this pattern, I can provide an example. On three separate occasions, I allowed my laptop to remain shut down for a span of two days. Upon powering it on after this period, I experienced uninterrupted performance without flickering for approximately four hours. Subsequently, the flickering issue returned.

I have exhaustively attempted a range of solutions that I came across on the internet while the screen flickering was actively occurring. Unfortunately, none of these attempted remedies yielded any successful results.
- Update Graphics Drivers - Not fixed the issue
- Adjust Display Refresh Rate - Not fixed the issue (Currently 60.01Hz)
- Boot in Safe Mode - Flickering observed in safe mode as well.
- Check for Malware - No malware in the system
- Disable Background Apps - Not fixed the issue
- Adjust Night Light Settings - Not fixed the issue
- Check External Devices - The issue is not found in an external system
- Check for Windows Updates - (Updated) Not fixed the issue
- Update BIOS - (Updated) Not fixed the issue
- Rollback Graphics Drivers - Not fixed the issue
- Display BIST test - Issue Not Found in test

I believe this pattern of behavior suggests a potential underlying cause, and I am seeking guidance on how to address and rectify this matter effectively.
