Phoned overclockers and told them the situation. It moved onto the point where gigabytes logo wouldn't even come up, could no longer even get into MIT settings.
But when putting the drives into my old pc, still had the same issue with them not loading. Went through the arduous taks of googling the whole bootrec fixmbr, fixboot, rebuild bcd, something as I said before I had to do years ago on one of these drives and came out the outside sorted. Got both drives up and running again doing that, boot files needed to be recreated and so on, but alas the crashes have just continued, again on my OLD pc, which is all Intel as opposed to AMD. Not that it's probably relevant.
Clockers have asked me to send it back and someone's picking it up tomoz, mainly cuz it won't get out of it's loop, with no hd's in at all, even after taking the cmos battery out for a while, it won't do a damn thing. I've just reinstalled W10 once again, fiurst time on this machine as it's always been W7. Among the searching I did see some things about people had problems cuz they installed from USB and when they installed from disk they never had problems again. Other than that I'm real curious to know what exactly happens in an operating systems that completely buggers the booting system so that you have to constantly go round in cicrles with all the differenet commands. So so confusing and time wasting. I just want a working computer.
