|Here lets keep this all on one Post okay, So we don't confuse everyone. |
So If one stick works and you don't get any graphical errors and with the other stick you get graphical errors and with both sticks the system does not boot. Then one of your sticks of ram is defective and your windows install is corrupted.
Let just check though. The one stick that you have that allows you to turn your computer on, does that stick work in both slots? If it does, then when the computer is starting, tap the F8 key.
Select repair my computer and proceed to log into the recovery console.
Now do a system restore back to an earlier date before your windows was corrupted.
Let me know how that goes.
