I am experienceing a start up issue with my desktop. When the power button is pressed the pc will begin its startup procedure but it stalls at the first DELL screen prior to any windows activity(this is the screen that conatains a power bar to show loading progress). I had this issue once before in 2011, and contacted a tech, who said it sounded like a 'power flea' issue. He said to disconnect the internet cable, and the power plug from the pc. Then depress the powere button and hold for a count of 40-45, Then reconnect the cabling, and press the start button once again. This seemed to solve the problem at the time. The problem began to resurface a month ago or so, but the solution doesn't seem to work on the first or second try. I have to redo the solution many times along with multiple depressing the nof the power button. After mnay attempts, it 'sometimes ' will start up.
What is causing this problem and how can I solve it??
