Laptop with AMD Ryzen 3 3200 display driver issue

[JamieAl]

I have a 3 year old Windows 10 HP 14-dk0501sa laptop and the display goes black and is only recoverable by switching off and on but is unuseable as if I try to do anything it goes to black screen again. In black screen the laptop is obviously still working as I get sound.  I've re-installed win 10 and it works ok but device manager shows a number of devices needing a driver update including Multimedia Controller, PCI Encryption, SM Bus and two unknown devices. The display adapter is listed as the Microsoft Basic Display Adapter. On the HP support website if I do an auto detect on the laptop I get a whole number of driver updates listed including an AMD Ryzen 3 3200u graphics driver but the HP site states no drivers need updated which is odd. The windows display driver works ok but on certain videos - netflix for example - you can see it's struggling and I can't change the resolution it's greyed out. If I go ahead and install the AMD graphics driver either through the HP site or direct from AMD I get the same black screen recurring and I cannot back out the AMD driver even in safe mode.  I've searched for an answer but cannot find anything so any help would be appreciated.

I think I may have found the issue. I decided to replace the RAM even though the BIOS system tests didn't throw up any errors even when running loop tests. I replaced the RAM and the laptop didn't go blank screen in about 8 hours of use. I then added the original RAM back into the laptop in slot 2, leaving the new RAM in slot 1. After about 4 hours the black screen issue reappeared. I took out the original RAM and left the laptop running on the new RAM only and it's been working fine for about 8 hours. I wonder if the original RAM has a thermal issue - that's the only thing I can think of.
