Hi, i have an emachines 8210 running win XP home. 3 years old. When i powered it on the other day, it started to load and then shut down. Left it until next morning and found pc was on, when i say on the power light and the hdd light was on and the fans running, but screen was dead. It would not power off with the power switch, so had to unplug from mains. Every time i plug the mains in, the lights come on and fans run, without touching front power on switch. Any help would be Appreciated.
