Wireless Networking Services
Report
Wireless Networking Services We seek to inform our clients about what type of wireless router works best in your environment and save you money in the process. There is nothing that inflames us more than when we see another computer service perform wireless router setup for you with insufficient or no security!That is like a doctor who is too lazy to perform CPR!There is nothing that irritates us more than when we see a technician purchase a whole new wireless router for their customer, when all they really needed to do was change a security setting or reset the router.Wireless connectivity may be crucial in your house, but when a router is configured incorrectly it exposes you to unnecessary risk.
Virus Removal
Report
Virus Removal Our company finds that virus, spyware, and malware infections are among the most prevalent problem for windows computers in the Orange County community. From San Clemente to Costa Mesa, and from Lake Forest to Rancho Santa Margarita, OCS handles virus, spyware, and malware with great frequency. We found that a large percentage of computers and laptops that run slowly contain spyware slowing them down.

When you get sick with a virus, you need special attention, or your condition is likely to get worse. The same is true if your computer is infected with a virus or viruses. If you need to speed up your computer, or realize your computer is affected, dont wait!

John is the most knowledgeable tech that I have ever worked with. I had software issues regarding my speaker and microphone set up when I added hardware that I needed to make audio books. My laptop speaker stopped working and my microphone started giving me static. John not only got my laptop speakers and microphone to work, he patiently worked to get the new hardware to work on my computer which was no small feat as the new hardware kept changing my computer settings. Now everything works! I am ecstatic!

Hi Ari, I thank you and your team for all of your help with recovering my data, replacing the hard drive and reloading the operating system/other programs onto my laptop. I would recommend Olympus to family and friends.

Ari, you did great work and completed it in just one day….Thank you for buying my stuff… I would have probably bought the wrong things. And you are not as expensive as other techs I have used before. I have your number and will call you back in case of trouble.

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.

John is the BEST! Available same or next day. Always on time & professional. He has done everything from virus removal to building my son a gaming computer. I don't trust anyone else with our computers!

Arie puts in 100% to try and get things fixed. That's a credit to him as most people these days I find pretty lazy. He resolved about 95% of my problems...all critical issues taken care of, which is great. But there are a few very very minor things that aren't resolved yet. He's trying to figure them out even after his work has been signed off on and paid for.

I also used his services a 2nd time for my laptop and everything was done promptly and correctly. 100%. I'd recommend him to anyone looking for a hard working trustworthy tech support.

After downloading messenger from a fake site, I was unable to access or do anything on my laptop. I called Ari after looking at the yelp review and being new in area, Ari arrived after an hour and half of the phone call and fixed the computer and got all my files back in the original place in less than two hours. And definitely save a lot of headache.

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.
