I have recently undergone some changes within my PC. I have switched to windows 7 64bit and tried adding more ram (which turned out to be incompatable) in the process. The other night windows was shutting down but had to do some updates, 182 to be exact! The same day I came home and tried to alter the RAM to look to see what I had! I then turned on my computer to see that my monitor just said no signal! I have tried everything! I tried resetting the cmos, reseating my RAM and graphics card and even replacing the cables and monitor I was using! My graphics card in an Nvidea GeForce GTX 660 and I was happily using 4gb RAM until I wanted more! Everything was fine until that day I don't know what happened? Can anyone help?
Yes I have placed all the ram back into its original position. And as for the windows DVD, I burnt the ISO image onto a disk to install it as I already had a key. The problem is my monitor doesn't show anything so I can't access any settings! And the cable is fine as I used the same cable and monitor to plug into my laptop and that worked fine.
Also something that did happen when I moved the RAM back to its original place was I started getting two beeps when my computer started after the usual one. I think this means a problem with the RAM but how it is now is what it was originally so I have no idea what has changed.
I did think that I could have dislpdged the graphics card but even when I plug the cable into the other connection on the PC (which I'm guessing is the intergrated graphics) it doesn't work! I will also try placing one stick of ram at a time to see if that helps.
