My computer shuts down at home

[beastintheeast]

Hello, The reason i say at home is I lugged it into the tech he plugged it in and it worked fine. I even had them upgrade the ram and install windows 7 enterprise. No problems get it home and it shuts down adn willnot power up for awhile.

That's strange. Did you try turning it on again (after the upgrade) at the tech. place?

Problems with the power supply (voltage?) at home?

Am having same problem, found that if I unplug it and wait a few minutes
it will boot, if you don't do this it will start to boot but after 4/5 sec, shut down again.
Am here trying to figure it out, Luck
