Peace, mercy, and blessings of God be upon you. I am offering you PC cleaning service, thermal paste replacement, and Windows upgrade or upgrade of the assembly from parts you bring or from the parts available with me. If you need a part and it is not available with me, send it to me and I will provide it for you, God willing. If you have complete parts from you, bring them, I will install the PC and install Windows, and you will have a one-week warranty. The price for cleaning service and anything else on the PC is only 50 SAR. You will have a one-week trial warranty after changing parts or anything you want on the device.
