Hi,
I bought a new ram module for my old pc wich i gifted to my sister some years ago.
I upgraded the ram from a Kingston KVR 1gb 1333MHz DDR3, to a Gskill 4gb 1333MHz DDR3.
Pc boots fine, bios settings ok (timings and voltage), however windows 8 won't boot (pc restarts while it's "Preparing Automatic Repair").
Tried reinstalling, windows installer wont even start (tried all windows versions from 7 to 10, 32 and 64bit).
Out of curiosity i tried a bootable Ubuntu USB and IT WORKED!
Ubuntu works fine. What's going on, it's driving me crazy.
Specs:
CPU : i3 530
GPU : Gtx 660
MoBo : MSI H55m-E33
