Our Ask the Experts section has a new question, where we have Jeff in the US having some problems with his HP desktop system.
Q: I have a HP Pavilion desktop that I purchased in late 2009. All of a sudden it has started shutting down. I have rebooted, I have cleaned out all the dust, Windows 7 has been rebooted with a disc. I carried to a computer technician who kept it for a week and it ran fine with him. No shut downs! I brought the computer back home and it started shutting down all over again. Windows will come up and a few seconds later it will say "logging off" and "shutting down". I have done everything I can think of. It ran fine with computer tech. it stayed on the whole time with hiim. What's wrong?
