Hello, John here, a new member, I been wanting to get involved in a tech. group for computers, I tryed fix it, but seems out of sorts for me,, so I will try here,, I have a number of computers I use, in time I will list all in my profile, for now I have one down for repair, its been faithful for some years, emachine T2682, it was running and just lost video signal and HD light stays on, have to force a shut down to reboot, it will run the post and to windows logo, it went into desktop first couple of first times rebooting'' the power supply stays running, the fan, but mother board cpu fan shuts off,,and don't forget HD light yellow just as monitor signal light also goes from green to yellow, I guess I just need some confidence, I will go with a power supply first? then a mother board combo of some kind that will fit in this case,, jump in here also on any help price wise to make a upgraded to this machine..I also did have a ATI PCI video card in this system. I pulled it and went back to on board video with same results, so people give me a hand, and i hope to be of help to others in the group as well, see bio or email me, messenger AIM is **** and Yahoo is **** I work on line all the time so keep me company while working,,, thanks, John
