Power Supply Replacement

You pushed the power button and your desktop is just unresponsive?

It might be a sign of a dead battery. PRO has experience in replacing power supply units for all types and models of desktops. It is a fairly straight-forward repair that takes around 2-3 business to complete, depending on the shipping times. As always, the issue might not be as clear and your computer not booting up might be caused by several issues. That is why PRO offers a free diagnosis on all issues!
