David did an amazing job saving my husband's computer. A week before my due date with our son, my…read morehusband spilled coffee on his laptop. I went to Apple and they told me it would be $1000 so we should just buy a new laptop. I thankfully then found Cosmic Computer on Google Maps and decided to seek another opinion. David was extremely kind and helpful- he took the computer apart and packaged it so I could take it home and air it out. He then put it back together, and it is working perfectly. We are extremely grateful, especially with our son's birth right around the corner. I'd highly recommend David.

Scammer. Used to bring my electronics here for several years, and all of a sudden the last laptop I…read morebrought to this place - I come back to pick it up and he tells me he returned it some company that called him and asked him to return this computer. None of this makes any sense. No notice of any kind, he did not call me to tell me this, no receipt or proof of anything! Just stole my laptop and lied about it. If you do bring anything to this place, ask for a receipt or some type of proof of drop off.

The guy here gave her great…read moreadvice on where to buy the replacement parts to get the best price (ie to buy refurbished instead of new, and in this case, to get it from Dell directly vs Ebay or a third party). His rates are half that of Circuit City and he is much more knowledgeable. He took less than a half hour to replace the screen and took care of disposing the old computer parts for us. The downside is that he is WAAAAY out there in the Sunset, and his storefront location is pretty run down looking. Cracked glass on the front door, hasn't been vacuumed recently etc.

If the manufacturer of your PC/parts can't diagnose the problem, just bring it here and for a very reasonable price they'll fix it right up. Toptek also sells a very wide range of stuff and can tell you exactly what to get if you tell them what you want. Their parts are also cheaper, and they'll install it for free, unless it's something like installing a new motherboard. They can also special order stuff and have it within 2 or 3 business days. They have been reliable for the past 5 years I have been going to them for advice and help.

He has…read morehelped set up my networks (everything from recommending hardware, pulling the actual wires and updating the system, and setting up the network and connections), troubleshot my teenagers' computer problems and most recently helped me when my built-in camera totally died after a suspected virus got me while I was on a zoom call. Does great work. He fixed my camera problems entirely remotely in this era of social distancing. He also set up better security software and fortified the protection I have so I can work more securely from home. He works on PCs too. Not just Macs as the name would imply. Highly recommended. He works quirky hours and is busy but he always comes to the rescue.

I truly had no idea what else to do, having exhausted my very rudimentary knowledge about how my computer actually works. i have had a couple of bad experiences at the "genius bar" (and a couple good experiences as well, to their credit), so I decided to give Danny a call after reading his excellent reviews here on Yelp. I am so glad I did! Danny was professional, knowledgeable, honest, and went above and beyond to help me with issues that were not even part of the initial problem. He really knows what he is doing, his rates are very reasonable, and he's really nice, too!

Not the best place…read more My phone back screen was cracked so I came here to get it replaced. It was about $200 to get the screen changed. I got it changed and came back a few days later because I dropped it. I didn't even drop it that hard and the screen still managed to crack. I had to pay again to get it replaced. When I received the phone back, they cracked my camera lens.... I confronted them and they said they didn't do that. Thankfully I took pictures prior to the service and I showed him that it wasn't cracked when I dropped it off. They eventually replaced it for free but didn't even own up to their mistake and got petty. Few months past and the screen cracked even worse. I know I shouldn't be dropping my phone but it happens. At the same time, I shouldn't have to be paying so much money for bad quality. I wouldn't come here again...

Do yourself a favor and call Comput N' Go for any technical problems with computers, servers, IP cameras, etc. He's a pro and a master of all IT.
