Great service.
Description of Work: Dell 8400 desktop computer would not start. Took computer to General Nanosystems store, the tech tested it, and indicated that the power supply was bad. He quoted a satisfactory price and we had him replace it. We were in and out in less than 1/2 hour with a repaired computer. We will DEFINITELY return to this company for future repairs or to purchase a new computer.

I would highly recommend this company. I've used this them 4 or 5 times in the last couple of years and I've always been impressed with the technician's competency, the short turnaround on repairs and the costs which were much lower that what I had expected.
Description of Work: Diagnosed and repaired faulty installation of Windows XP and replaced a cooling fan that was failing.

General Nano is wonderful! If you have any PC problem, just bring your box and walk right in. The technical wizards are swarming about and will take care of you in a jiffy. I've had them build my last two or three computers and have been more than satisfied every time. This last one was a problem, because I had a heater plugged into the same circuit and it was frying the motherboard. They replaced the original twice (at no charge) and worked with me to figure out the problem, no issues since. They're very fast, usually they can fix the problem right then and there, on a walk-in basis. If not, and the parts are in stock (which they usually are), you can expect to pick up your machine the next day. Prices are incredibly reasonable and the tech staff is wonderful. Those with little to no computer savvy need not worry, they won't make you feel silly. Very helpful and knowledgeable group!
Description of Work: Consulting and replacement of a motherboard, three times in a newly-built computer.

TECHNICIAN AMINE WAS SUPER. HE CALLED ME SEVERAL TIMES TO VERIFY WHAT I WANTED AND WHEN I GOT THE PC BACK IT WORKED JUST AS BEFORE WITH NO NEED TO INSTALL EVERYTHING OVER AGAIN. THE PEOPLE IN THE REPAIR DEPARTMENT WERE ALL VERY RESPONSIVE ON THE PHONE AND HELPFUL. I WILL TAKE MY PC THERE FOR REPAIRS OR UPGRADE FROM NOW ON!
Description of Work: MY PC QUIT. TOOK TO BEST BUY GEEK SQUAD. MOTHER BOARD SHOT. GEEK SAYS THEY DO NOT REPLACE, BETTER TO BUY A NEW PC. TOOK PC TO GENERAL NANOSYSTEMS. THEY VERIFIED MB SHOT, BUT THAT BOARD WAS NO LONGER MADE. TECHNICIAN AMINE FOUND A 'RE-MANUFACTURED BOARD' THAT MATCHED (SAVING ME HAVING TO RELOAD ALL SOFTWARE) AND INSTALLED IT. BOARD WAS $40 AND LABOR $60. A GREAT VALUE.
