    CSI Technical Services have a Free Diagnostic service, so I thought I would give them a shot since I was not successful.

    I can't say enough great things about Matt. He absolutely saved me this week…read more My Lenovo laptop completely failed to boot after a graphics driver cleanup utility corrupted the Windows boot configuration and recovery environment. The system was stuck in a recovery loop, BitLocker was triggered, and Windows wouldn't load or even reliably enter repair mode. Multiple shops I called said it would take several days just to diagnose the issue. Matt turned it around in essentially one day. He was able to manually access the system, unlock BitLocker, repair the corrupted boot configuration, rebuild the necessary Windows files, and get the machine fully operational again -- without wiping my data. That was critical, as I had local files that weren't backed up to the cloud. Beyond the technical expertise, what impressed me most was: * Clear communication * Fast turnaround * Extremely reasonable pricing * No upselling, no unnecessary "reinstall everything" approach He diagnosed the real issue quickly and fixed it correctly the first time. If you're an independent contractor who depends on your machine daily, or you run a small to mid-sized business and need reliable, competent IT support, Matt is exactly who you want on your side. Look no further. Highly, highly recommend.

    The other week, on a Monday, I spilled some coffee on my Dell laptop. When I called initially,…read moreEric said they were really busy and couldn't get to it that day. They called me back the following day and had me drop off the computer around 1:00 p.m.. Luckily, they were able to clean it and get it working the following morning. I was really surprised they could get it back to me so quickly. They even took pictures of the coffee on the motherboard, under the keyboard...it was really gross! I felt bad for having them clean up my mess, but it was certainly easier, faster and more economical to fix what I already had.

    My wife's Toshiba laptop died this winter while we stayed out in Arizona...ok no big deal except…read morethat all her old photos from her original two Droid smartphones was on there and not backed up. Thousands of photos of her mother (RIP) her family, the grandkids. Best Buy Geek Squad looked at it and said nope, nadda , zip..it's dead. Hard drive crashed and is trash.. Can't recover anything. My wife was inconsolable. I didn't 100% trust the opinion of the Best Buy technicians so with hopes of a save I brought the laptop home with me to Illinois. I went to some guys I trust. WavTek Computer service in Crystal Lake. They have very sophisticated equipment to diagnose and retrieve data. Long story short, they recovered everything. They saved everything to a external drive. She has her photos again. To say my wife was ecstatic is an understatement. Emotional tears of joy. Understand they are not a retail store, they are service and network professionals. WavTek saved the day and I highly recommend them.

    I had an intro call that went over two hours, all great next steps but almost overly thorough (in…read morehindsight). But either way, I left the call thinking we'd have some great momentum and he promised to review our past taxes and our 2025 submission. Well, zero follow up. I signed a contract and then ghosted. Then my husband was bothered by this since I had sent him all our private info, so he called Kyle and got the same promises. Nothing again, and we keep trying to get in touch. If he's busy, just say so! But don't request all our very personal, identity documents then fall off the grid. Very very unsettling and more importantly HIGHLY unprofessional. I was looking forward to working with him! But seems like professional maturity and stability is highly lacking, beware. UPDATE FROM KFN RESPONSE: I'm a professional project manager, there is absolutely no way I would miss a meeting I had been adamantly requesting for weeks. It's disappointing how unbelievably inaccurate this response is, to the point I may need to alert Yelp itself. I tried to reach you number of times and I even had my husband reach out since it was an unknown number and maybe you'd answer. Which you did, and ghosted him as well. I wouldn't make this up, lying about it should be a huge red flag for anyone reading this.

    Hired KFN to do my business tax return as well as my personal taxes. Amazing quality, value and…read moreservice. They reviewed prior years returns and found numerous mistakes and/or missed opportunities and amended them resulting in significant money refunded. We use to use one of the big accounting firms, never again! KFN is diligent, very knowledgeable and ask questions that I would have never thought about which helped save significant. overall 10/10! highly recommend!
