Video card going out?

A couple days ago I turned my Lenovo ThinkPad laptop off after it being on all night. Left off maybe 5-10 minutes & booted back up, all was fine at first then it looked like the screen had been shattered (it wasn't) but it appeared to be shaking. I powered off & let it sit a bit, removed battery & pushed power on button for about 30 seconds. Plugged it back in with out battery & all seemed fine for many many hours till some time this morning when I heard a strange hum, saw screen like the first time, powered off again. Hours later I booted it up, it is again running ok, I checked Device Manager & NO Exclamation marks ANY where. I do have an extra monitor I can hook up but I fear the video card might be going out????

Sounds like an overheating issue. In addition to cleaning out dust, you may want to explore replacing TIM and/or thermal pads. Do you feel any hot spots? Does a temp utility show anything above norm?

@Cycloid Torus can you tell by the above posts # 6 & 7 if the laptop is too hot? I'm asking because I now think it was ROOM temp too hot . Laptop has been functioning fine since summer quit, room temps in the upper 50's :)

CPU temps look fine.
"strange hum", "screen..shaking" - if not temps or dust bunnies then likely developing failure in power system (charger, battery, power regulation chips, cold/failing solder joint, capacitor) - test by making swap charger & battery with known good - coin battery?

I'm not able to swap charger/battery & since its a laptop, I won't take it apart to change coin battery. Yes, I can be wrong, but since its been running fine these past few days, I think it was the extreme temps in my place. Will see how it goes these next few days, thanks again.
