My computer froze and the screen went blank a few weeks ago. A scarry situation, when you know nothing about computers but rely on them on a daily basis. I found Datalink Computer Services, and I was impressed with their knowledge and commitment to customer service. The initial diagnostics they ran on my computer said I needed a new graphics card and hard drive. They quickly replaced both, and returned the computer to me. I started having wierd problems. After several phone calls to Brian, with no change, they suggested bringing the computer back to them- they even provided a loaner computer. They had my computer an additional week, and found two more problems. They made the additional repairs, including installing some new hardware, and returned the computer to me- without any additional charges. I was very impressed with their service, knowledge, and commitment to the customer, and I will never go anywhere else for my computer needs.
