Have this problem that started yesterday PM. Worked on it all day today with no results. Called Acer Tech Suppt - their only suggestion was to reformat and restart from the factory image. Let me see if someone here has some other suggestions before we take that drastic a step.
Acer Veriton M265 - with Win XP Pro SP3 - fully updated. 2gB RAM, large disk - half full. Using a dual video card Radeon 4350 to twin monitors. This system was set up and has been running very smoothly since 2/2010. What happens is after about 5-10 minutes sometimes I can get an hour out of it, the screens go completely black, their power buttons go from green to orange. I look on the computer case and the power light is still lit on. I carefully removed the case cover to see that the fans were still running. Rebooted and it happens very reliably after about 5-10 minutes. I established a new user. Logged in there, same thing. I removed the computer from the APC, plugged directly into the surge suppressor - same thing. I then took out the Radeon dual video card and used the on-board vid - same thing. I replaced the keyboard because it usually bombs when I'm typing - no difference. I watch the drive light carefully as I press Windows-E to launch Windows Explorer - I'm looking for some sign of life - there is none. I looked through the event logs - they are pristine. I looked through the BIOS to see if a power setting needs change - they look good. I went into Windows to check the APM setup - turning off everything I could, including screensaver timeouts, Windows power settings, etc. Still bombs. I tried a restore point from two days back. It didn't stay alive long enough but on a subsequent reboot, Windows reports a succesful restore to 9/6.
It's basically just shutting off but not powering off and the only way to recover is to hold the power button in for 10 seconds until the power releases. The computer gives me no indication as to what's wrong - no event log either application or system, and no error box or BSOD.
I'm leaving it sit on the BIOS screen to see what happens overnight.
Does this look like a hardware issue? What's your best guess as to what piece has gone sour.
Does this look like Windows being Windows? Again, although restore point didn't complete, it did complete subsequently on a later reboot. But with the same result after about 5-10 minutes.
Hope for some help. We're still under warrantee.
