Hello leon.LEE.

Either the CPU, the rack it sits in, or the PSU in the rack is defective, or there is excessive electrical noise in the plant.

How you Jesper assume that? Do you think that there is so much electrical interference that it corrupts units ram? And how can it be from defective rack if so?
