I have 2 1/2n year old HP Envy dv6. When I bought it, I had just been diagnosed with Stage IV throat cancer and was told my recovery (if any) would be very long and painful. I bought the best non-gaming machine I could buy. Long story short, I got some kind of crazy virus, so I chunked the hard drive and bought Windows 8.1. Unfortunately for me I installed, I installed the 32 bit version of Windows instead of the 64 bit version It barely ran for 6 months until I realized my mistake. I took it to a place in San Marcos, Texas to install the 64 bit OS. I didn't have the disk, but I still had the original password that came with the software. After a month of them telling me they were working on it, I asked Thumbtack to help find a competent company to fix my computer. Betaone was the first company to return my phone call. They came to my house, replaced a computer screen on another laptop I own in less an hour and took my Envy home and brought it back the next day and it has been running perfectly ever since. They only charge an absurdly low $15 an hour, and they don't charge for travel time. They look up the parts you need and you buy them online.I am an extremely satisfied customer.
