Helo guys, it’s me topic started.
So basically, I had the issue with entire PC freezing, in December I did full new fresh install of Windows on a new hard drive, instead of freezing it started to restart. I give up with my laptop and I was even thinking to stop using UE4, then in March I decided to do the another try with no hope, I just replaced my RAM plates, I have 4 of 16GB, I just swap them all, I did a memtest and I got 108 error, I was like ■■■■, anyways, too lazy to deal with them, G.Skill support did not help and I was going to replace it with new, but their warranty policy made it impossible and very expensive, I had to pay for everything and then may not return it back in case if something is wrong, but then I’ve noticed my PC is working good now, I even switched 2400Mhz to 3000Mhz and I run UE4 since that time with no problem, I only can suggest to swap RAM plates and this is what cured my problem, even having 108 errors did not affect it and I don’t really have crashes anymore. No drives issues, no BIOS issues, just a swaping RAM plates.
Look to your RAM,in your case you may have to replace it, get new one, in my case switching in places was helped me.
