Hello Everyone! Could some one Please! Help! I have a Sager 9750 that has worked Great for me for the past 4 years,until recently my screen woul go black and shut down. So I checked the video card and found that 1 of the 4 posts that hold it down came off the board! It is a Nvidea 7800 Ge force go video card, so I ordered a new motherboard from Ztronics.com 200.00, Im pretty sure that I put everything back together right, Now it still wont come on My screen is Black and I have 3 flashing Green lights, then it shuts down! The Video card looks good but, I guess that dont mean much, and the fans dont even come on. Any Help would be VERY MUCH APPRECIATED! Thank,s! jackkent@comcast.net
