having problems reinstalling windows 8 after wiped hdd

[ashmal]

the laptop:
HP G6 2249WM
it came preinstalled with either win 8 or 8.1, I don't know which as I wasn't the original owner.

I took apart the laptop a few days ago because it was overheating, found the fan blocked with lumps of dust so I cleaned it all out and replaced the thermal paste. When I put it back together and turned it on, it wouldn't boot, I kept getting error messages on a blue screen, they were different each time I restarted. I used windows 8 media creation tool to make a installation usb but when I boot from that I still get errors on the blue screen and I tried with windows 10 media creation tool to install on usb but I still get error message with that too.

so I took out the hdd and plugged it into my other laptop (which I'm using now) with a usb connector and used paragon partition manager to delete all the hdd partitions.
windows still didn't install.
iv tried putting it in legacy mode but I still get error messages too.
ran a test on the hdd and memory in the uefi/bios and they are working fine.

any ideas of how I can get it working?

(the dvd drive on the laptop isn't working)

Nothing can be said until you say what errors are cropping up. It could literally be everything from you getting the wrong install media to total system failure.

Did you make sure you formatted it to the NTFS format?

I fixed it. ran a full ram test instead of a quick one and it failed around half way through. replaced it and windows installed fine
