Hello! I am new to the boards but from what I have seen this will be the place to come from now on I upgraded my memory tonight from 128 to 512 (rambus). Install was of course easy and had no beeps at start. Now windows will not boot all the way. If I hit restart it takes me to the options page (safe/normal/ect). I hit f1 at start to check my settings and all seemed fine so I continued from there and after getting to the windows page it errored out and said that windows did not load properly! I replaced the old memory and am now getting the same result as with the new. I did not change anything before or after installing the memory. if anyone has an idea of what went wrong here, please let me know thanks!
