Lenovo T470 - graphics card/driver issue? Black screen w flickering white boxes

My encrypted Thinkpad T470 (2yrs old) has suddenly begun "crashing" during use. This doesn't seem to be triggered by any particular programs or user behaviour that I can identify, and once it happens it will occur again relatively soon if I restart it without a long rest.

 

What happens is that the screen goes black, and white boxes flicker in and out. Sometimes I see white lines near the top, which I associate with graphics card issues, but I've never seen this white boxes pattern before. The laptp will not project on an external monitor, so it's not just a display issue. It does not fully shut down when this happens, but rather requires a force quit in order to restart. It restarts normally until it crashes again.

 

Any ideas on what is happening here? Am I on the right track to suspect graphics card issues? Thanks.

Hi DG16! Welcome to our forums community. Could you try booting to BIOS and check if the issue persist. The instruction is here: https://support.lenovo.com/us/en/solutions/ht500222. If yes, the issue is hardware. If not, run the hardware test from the Lenovo Vantage app. You can get it here: https://www.microsoft.com/en-us/p/lenovo-vantage/9wzdncrfj4mv?activetab=pivotSmiley Surprisedverviewtab. This will help identify a hardware failure. If the issue is hardware, you can bring it to any of our list of authorized service centers. Here is the list: https://support.lenovo.com/in/en/solutions/ht118678?CID=ww:lenovosocial:20x9m6. You may also reach out to our support here: https://pcsupport.lenovo.com/us/en/SupportPhoneList?CID=ww:lenovosocial:20x9m6.
