What does “PC Tune-Up” mean?

There’s a lot of conflict, double-talk, and horse-shtomping when we hear or read about a Tune-Up. There’s this website, that program, this price, that subscription, and it can be confusing.

Let us lay our cards on the table and let you know what we do when we do a Tune-Up. It’s enough information for you to almost do it yourself or for another tech to copy, but that’s okay with us, we’re here to help – directly or indirectly.

  • We check out the entire computer.
    • Physical inspection
    • Remove all internal dust
    • Check all fans and heat-generating sources
    • Run tests on the hardware to make sure all is well
  • Then we move onto the Tune-up
    • We measure the start time of the computer
    • Check everything that loads at start
    • Check the Windows Event Log (Often forgotten about)
    • Disable non-essential programs from loading at start
    • Disable non-essential, erroneous services from loading
    • Reboot
    • Uninstall all unnecessary software using special tools to remove all traces
    • Look for malicious software (Malware, Adware, Spyware, etc)
    • Update all essential software
      • Adobe Flash
      • Adobe Reader
      • Oracle’s Java
      • All Microsoft Updates
      • All browser updates
        • We also check browser plugins/extensions
    • Reboot and remeasure start time of the computer
    • Perform a shutdown of the PC – It’s in our opinion that a fast shutdown is also a sign of health.
  • At the Finish
    • We physically clean the PC
    • Have a different technician run a Quality Control Check
    • Contact the client by text, email or phone.
  • At pickup
    • We take the time to show the client their computer
      • Including what work we performed
      • What we found
      • And show them that everything is working as it should

And we back it all, with a 30 day, no questions asked, guarantee.

  • The team at Credo Technology Group was absolutely wonderful. I went in to ask a question and they ended up redoing all kinds of things on my computer. Found out it wasn't my computer that had the problem but my previous email provider. They fixed the problem and I am so grateful. 100's of kudos to this wonderful group of technicians.
  • Eric and the guys are great! I brought my PC into them because it was running slow and not starting half the time. I fully expected to have to by a new one. In a very short time they gave it back to me in like new condition at a fraction of the cost of a new one. I'm very happy with the service and my PC never ran better. I highly recommend Credo to anyone with PC related issues. Dan Barrett
  • While I was off on vacation, I had Credo ghost and replace the hard drive in my laptop. They did a great job, had all of the Windows updates installed for me and gave me some free advice on how to make my laptop run even better. I’ve known Eric for several years and have always been impressed by him personally and how he runs his business. He and Mario are top-notch people: honest, ethical, fair and upfront regarding any issues you should be aware of. If you need your computer repaired (for work or home), I highly recommend Credo Technology Group.

  • I used Credo a few times with my computer issues and just recently had them build me a custom gaming machine. I am truly impressed with the both the quality of the computer they built within the budget I gave them and the speed in which it was built. I also just had them do some laptop repairs and upgrades and again, they over exceeded my expectations in both time and price. We are going to let Eric create a webpage for our business after seeing the great work he does for others and the very reasonable prices he offers. Thank you Eric, you and your staff are amazing.
  • This crew of technical wizards sure knows their technology. A fantastic work ethic and dedication to detail and customer service. Their advice on integrating my household and business systems proved to be a real time and money saver. My work day goes much easier thanks to this amazing group of humans.
  • Do a great job. Honest evaluation of problem.
  • Great customer service, all of the employees do a great job welcoming new customers to the shop. This is the place to go for any issues
  • I think the staff is awesome.  Each and every one of them have been so nice and helpful.  I can call any time to get advise and they have been so nice answering all my questions.  I especially like that they don't try to sell you on something you don't need, or try to get more money out of you.
  • My computer got a virus and they repaired it and I lost no data. They also set me up with cloud back up. They are very friendly nad nice people to deal with.
  • The guys there are very friendly and had our laptop up and running in no time. We felt the price was fair for what they had to do.  We will totally use them again and recommend their service.

I recommend this group to those needing computer and laptop repair also dir website design.  I will recommend them to all my friends.
  • My computer just shut down and would not restart. I use the computer for my work, so this was a disaster! I took it to Credo and they were on it! Alejandro first had all the dust blown out and then determined that the fan on my video card was not working properly and replaced it. The were fast, efficient and did not do anything that would cost me more money and I would recommend them to anyone needing their computer repaired. They are local and go out of their way to make you feel comfortable and do what's needed to fix your problem. If I have any more problems in the future, they are who I will call!
  • Alejandro, Thanks for your help setting up my cameras. You were great to work with and helping me out. Everything is working fine. If I ever need more help it will be from your company. A job well done. Thanks for your help.
  • I've used Credo Technology Group for all of my computer repairs, as well as, IT for my business. They maintain a high quality of service and have repaired or debugged my personal and business computers. I wouldn't take my computers to anyone else!
  • Fantastic crew. Let me know when the ordered parts were in so I could drop off my computer, Had it completed earlier than they had estimated for very close to their estimated cost. My computer runs very well now. Highly recommended!
  • I cannot say enough about the good jobs Credo and Alejandro have done for me. I am a bit technologically challenged. Most times I muddled through minor troubles that my grandkids chuckle about--but when I really need help Alejandro comes through for me . He arrives on time, is extremely polite and knowledgeable--fixes all my problems and then makes good suggestions about avoiding future mishaps and recommends software that is understandable and works. I was really struggling with Windows 8 on my new computer and Alejandro saved the day for me. I bought 4 books on Windows 8 and struggled for weeks with them. I was up and running in less than 15 minutes. I love the guy. Mike Hess
  • My hard drive failed but was still insured with an extended warranty from Amex.  Credo Tech diagnosed the problem and waited patiently while my claim was approved.  Once I gave them the ok to fix the thing, it seemed as if it was fixed a few hours later and I could come pick it up.  I received prompt, FAST, friendly service and my computer is running better than ever before with a recommended hard drive upgrade and a few extras thrown in at no cost!  Thank you very much!
  • The BEST! No other shop in the area provides the high level of service that Alejandro provides. He just installed a refurbished desktop using Ubuntu as an OS and we are blown away. Credo's advice is always on the mark. Alejandro is a very special person and incredible to work with. Thanks for your help!
  • Credo is the best!  They've helped us with techno issues many times and always with good results.  They're professional, prompt and knowledgeable.  I recommend them to anyone who is having computer issues!  I'll be a customer forever.
  • Credo, and particularly our experience with Alejandro was excellent. He is multi-tallented, putting in a whole house audio system, surround sound, networking, as well as assisting us with hardware and software with our computers. He worked with us to help determine what we needed, and then acted accordingly. He did this all at a very reasonable cost. We are pleased to recommend Alejandro, and Credo for your Technological needs.
