Even when done right, things still can get screwy when you don't wipe the drive. The IRQs you mentioned is a prime example. Trust me, just format the drive and install all the appropriate drivers and software. It just leads to less headache in the longrun

so it w0ont be normal i will still have screw ups here and there?
