One of the biggest problems for PC's on the Internet these days is the onslaught of Viruses, Spyware, Malware, and Scams targeted at Windows Computers. At some point users get infected and the computer either crashes, throws up numerous errors, and/or usually kicks you off the Internet. Many times the user will take the machine to the Geek Squad or some other repair place and end up getting their system completely wiped out! Most Tech guys do not know how to completely remove viruses, so they wipe out your Windows installation and install a new copy.
A system Crash: If you're lucky, it only happens occasionally, more than likely though it will continue to crash as systems rarely fail only once. Rather, they keep crashing until you find the cause and fix the problem. A crash (or system crash) in computing is a condition where a computer or a program, either an application or part of the operating system, ceases to function properly, often exiting after encountering errors. The offending program may appear to freeze or hang until a BSOD details the crash.

John is terrific! Been taking care of our computers for several years; the last recovering a hard drive crash. Very personable, highly intelligent, knows all the ins and outs of computers and their problems. Always prompt, does exactly what he says--and usually more. Couldn't ask for better, more competent support!

I agree with other reviewers - John is the BEST ever. He is knowledgeable, professional and provides fast service. We decided to get more speed out of our computer and John stopped by the very day I called at exactly the time he said he would be there. He took our computer with him and had it back the next day. John also took the time to optimize Windows and check for Malware.
When he brought the machine back he again arrived exactly when he said he would and took time to make some more recommendations. John's price was very fair and exactly what he quoted it would be. We won't trust anyone else with our computers again. Thank you, John. It was a real pleasure dealing with you. Nancy & Tony

Fast and stellar service! My computer wouldn't boot. I called John who was able to come by on the same afternoon and diagnosis the issue - a bad motherboard. Knowing I needed the computer operational immediately, I had John take the computer to replace the motherboard (parts and labor). He immediately worked on the issue and still had it to me later that day.
It was a Saturday and he still came back to return it at my home late that night. Now that's service! The wife's happy that the computer is functioning again as well. For his hard work and quick turn around I thought the price was very fair. If you have a computer issue, consider John for the work.

We have used John for several years and can't possibly say enough good things about him. We had XP on our business computer (we have a tax business), but the tax provider would no longer enable us to use XP. John came and in no time we had Windows 7 on the same computer! You will never be sorry you called him. Frank and Betty G.

I have a 2-year old HP dv4 laptop that was hung-up with a blank screen. It would not boot, nor could I get any control by using Esc, F8 or F10. I took it to where it was purchased (Best Buy), and they said it could be any H/W component. If they took it, it would be shipped out to a Repair Depot, and it would not be back for at least four weeks. So I did not leave my computer there.
I looked on-line for a local repair service in south Orange County and found Magnum Computers. The ad said they will come to your home/business, 24/7, experienced and certified, and the reviews on multiple web sites were very good. So I took a chance on them. The repairman came out to my house on a Saturday (at no cost), evaluated my laptop, and told me he was 100% sure it was the motherboard.
He said the cost for a new motherboard was about $300, and the labor would be about $100, and he would have the laptop ready by Wednesday. All of this was true, and I have a working laptop again (with a new one year HP warranty on the motherboard). It is hard to find a knowledgeable, honest, and prompt service company, but Magnum Computers is just that.
