The hard drive of my computer has been changed twice already, then when the system failed to boot again, a supervisor determined that the problem was with the motherboard, which was changed on June 26, and a week later my computer either failed again to boot or started and minutes later froze, showed a blue screen or a scrambled screen or a variety of error messages.
This situation has been going on since November last year, it is not only absolutely frustrating, but simply unacceptable as you can well imagine, since I am unable to perform professional duties due to its erratic performance. It is a major disruption on many levels that I am not willing to bear any longer. Either you solve this problem once and for all or I will have to demand restitution or a new computer.
