I own computer shops.... we turn it OFF on all machines we sell...
All the best Brett
Glad I dont buy my computers from you.. I would expect a comp to be provided in fully working order.
If I buy a car.. I expect the radio to work.. I dont expect the supplier to remove it in case it breaks.
Anyway - to OP.. I presume you have checked latest drivers on all components?.. esp motherboard?.. and latest BIOS?
and have to tweaked anything? overclock or anything? You not given us anything/much to go on.
