Hello to all.
As the tittle says i have a HP Workstation Z620 and 2 days ago suddenly the screen shows horizontal white lines in all the monitor.
I don´t install nothing new (harware or Software).
Somebody have any idea what can be?
Has someone something similar happened?
Many thanks in advance.
kind regards.
