Hi This is my first problem post. My eMachine T2682 now freezes up. The screen locks up. I have to power off manually and re-boot. For years the pc hasn't powered off. It will shut down win xp, but then the yellow hard drive light comes on and just stays on. No one has ever been able to tell me how to fix it. I replaced the psu years ago thinking it would cure this problem. It didn't. My new problem is that when I power on, sometimes the pc remains dead. I click power on and off a few times, and it comes on. Then I do multiple boot attempts until it quits freezing up during boot. This was my old new problem of a couple of months ago. Very frustrating. The pc freezes up a every now and then once booted and warmed up. But, I can usually stay running once up and going a while. I am about to order a new psu from directron. Let them pick a quality unit for the right price. I am price sensitive. I may wait and read some replies, first. I don't do much on this pc. I surf, read newspapers, stream tunes, email. It is a home unit. Just me. So no games. No gamers. I added a gig of ram from crucial a year or more ago. It didn't really speed anything up that i noticed. i had expected a miracle. I can stream a movie from Netflix and multiple audio w/ no problems. I have broadband from YahooATT. I am satisfied. This pc does all I require. But it has boot and powerdown problems. If you have any advice, I'm all eyes. Thanks - Analogtip.
