The tech guys at The Source in Midland did a great job and resolved the flaky problems with my tower PC running with Vista Home. There were a couple of software conflicts in the startup but the main issue was the memory sockets in the motherboard. They moved two sticks of memory to the other two available sockets and it all smoothed out. This was a long standing intermittent problem that the Tech guys at Staples in Midland were unable to solve. Staples also charged more almost double what the Source guys did, and the Source guys actually solved it. I will be bringing all my tech troubles to them in the future. The tower is an HP of about two years vintage.
