New Computer Build but kept the old HDD

[justin-bc]

A friend asked me to Upgrade his computer for him as he got excited when he seen i built myself a new PC. Now almost everything in his computer is new minus the Case, Power supply, HDD, and graphics card. His build is
CoolerMaster Case (older one Mid Atx Tower)
Intel Core i7-8700 3.2ghz
Asrock-B360 Pro ATX LGA1151 Mobo
Gskill Aegis 8gb DDR4-3000Mhz ram
Cant remember what kind of HDD but its 1.5tb from the old computer
Geforce GTX 1070 8gb MSI
EVGA 600w Power Supply
Windows 10 64bit (upgraded on old PC from windows 7 not a fresh windows 10 install).
Now ive had other friends upgrade their computers Ie. Mobo and CPU whilst keeping their old drives and not doing a fresh windows update and everything runs fine. But with my buddys new build here funny things are happening -.- He can run the computer normally running youtube or doing whatever normal browsers do and even run minor games like league and his indie games, but when he tries to run PUBG or Overwatch or anything demanding really he says it sounds like all his fans start firing up to full tilt then his computer crashes and reboots on its own. Now he even tried installing a brand new game hes been wanting (monster hunter) and even that game with a fresh install and never being on this computer before crashes. We went thru and did all the usual stuff check all the drivers and make sure their all up to date, try running things through admin still nadda. I'm at the point where im guessing we just need to do a fresh windows install and reinstall everything and start fresh?


*UPDATE* Currently playing league with him and getting him to open a bunch of Google tabs with youtube running videos in the background, no problems what so ever. Running 300+ FPS and 6 tabs open in google all on youtube. yet we try and run PUBG again, same thing as before. Computer winds all fans to full tilt and forces a reboot.-.-

1. Sometimes it works
2. Sometimes it fails completely
3. Sometimes it works, but you discover little issues for weeks.

Seems that you have found #3.

Yup, full install. It's the best practice for a reason. It's one thing to leave yourself having to do things over again because you wished to skip a step, it's quite another to cut a corner on someone else's PC and leave them with a possible mess to deal with.

By no means am i leaving this with him to deal with, i did all the work getting the parts and making sure they were compatible and then puting everything together. I fully intend to do all the work it takes to get his PC working as it should im just asking for some help as clearly i need to learn more. What would be the safest way to reinstall tho? Format the drive and buy a new copy of windows and start there? He doesnt own a copy of windows 10 as he updated it from windows 7 a while back.

Did the swap keep windows activated? right click the window logo in the lower left task bar, go to settings, in the left tab click activation, what does it say in the top right? If it is licensed, use the windows 10 media creation tool and make a USB installer that you can reinstall from.

You my sir are a G, You are completly right his copy of windows cant be activated on that device becouse he doesnt have a valid product key. thank you for throwing that out there!

If you still have the old hardware setup a test bench, boot the hard drive with it and see if it reactivates. Then link it to a MS account, and then put the drive back in the new pc and follow the activation troubleshooter.

I don't know if the above still works though.

You can still get the re-install media from MS for a fresh install, and run windows without activation for a bit. When you get a licensed copy without needing a reinstall then you can add the key.

Soo........I wanna thank everyone that commented on this thread trying to help me out with this issue! Turns out im just a friggin dunce! xD
Theres the volt switch on the back of the PSU that can be set at either 115volts for NA and 230 for EU and uhhh i guess it got switched to 230 at some point during the upgrades? sooooo flipped the switch and umm all problems have been solved xD thanks again to everyone helping out and im sorry i was just an idiot xD hell man lesson learned lol

Ummm, is that actually an EVGA power supply? I don't think there are any EVGA-branded power supplies old enough to have that voltage switch - that's a telltale sign of a power supply that is either extremely old or extremely low quality.
