system was on then i shut it down and upped the ram from 2 gbs to 4 gbs. now it wont provide a video signal. i tried the jumpers and removing the battery. resated and switched out the graphics. put the old memory back in, took one out and so on yet it refuses to work
Verify that your GPU (video card) is securely plugged into the motherboard and that all of your power connectors are securely fastened (including the one to your GPU if it has one). Often users will bump a connector/card when installing new stuff and cause a minor disconnect issue. Good luck!
You shouldn't have any problems, per se, but you may still have to re-activate your OS (assuming Win 7). Even that isn't a big deal, even if you have to call MS should the automatic/on-line activation fail if you are using legitimate software.
BTW, will the system boot properly with only the original 2GB of RAM installed?
system will not register at all no matter what i do. tried putting org ram back in, switched slots, removed gtx 260 several times and reseated, put org gpu 8400gs back in to see if it was the gtx 260 since there is no video output. NOTHING. it comes on just no picture. everything else hooked up to tv shows up perfectly so its not that.
Try to manually reset the mobo (if you haven't already tried) by disconnecting the power cable, pressing the power button to discharge residual power in the system, and then pulling the battery from the motherboard itself. Wit 30 secs and reverse the procedure.
If it is still dead afterwards, the mobo is defective (most likely) and you'll need another. Sorry for your hassles.
