Hello,
I recently got a used HP a1640n. I replaced the hard drive and purchased Win 7 to install. When I turn on the computer I get a long beeping noise and my monitor gets these vertical green lines on it that seem to shake. Can someone tell me if this is a connector problem, a motherboard problem or something else. I checked my connections, memory and power they all seem to be working fine. Please help if you can.
