I have a HP laptop running Windows 10, with a Intel i-7 7200u I believe, with 12gb of ddr4 RAM. I am having trouble transferring files from an external HDD to another external HDD. The folders I am trying to transfer are upwards of about 30 GB each the transfer will start then it will freeze, my screen will go blank and the only option I have is to press Ctrl+Alt+delete and then restart my laptop. And then sometimes it will be in the process of transferring and suddenly one of the HDD will unmount. So I'll go to this pc check that's it's actually unmounted then unplug and replug in the HDD, then file explorer will take forever to load the HDD, it will say"working on it" and most of the time after waiting like 10 or 15 mins I'll just say screw it and restart the computer, that is unless my screen doesn't go blank again. I have tried using teracopy and that will report a bunch of errors and I've tried just using Windows to transfer the files, I've tried copy, and paste, and dragging the folder over to the destination folder, and I've tried the send to... Option and it's messed up in all those options at various times. I am trying to move about 300GBs of files. Could it be a RAM problem, do I need more RAM to move such large files? Please help, I won't be able to answer back til after 8pm tonight.
