I strongly doubt it has anything to do with the chip, since this has remained untouched since it was first time installed. It has worked fine for a very long time, with a 120gb harddrive.
At some point the drive was taken out, wiped and used in a windows pc, the xbox has been lying safely in a box until recently. I tried putting the same harddrive back ( formatted it, even made it RAW using some software, and when all that failed i tried this xboxHDM thingy)
So far no good.
My guess would be then that these installs would be corrupted, but i also seriously doubt this one because i have downloaded several versions of slayers, severeal times, downloaded xboxhdm twice, put at least 4 kinds of different software in the C folders ( varying from original xbox dash to evox to avalaunch)
So far no succes
