For a while this morning after messing about with my new Ram I came to the conclustion that I screwed up big time. I did something im not sure what it was and my PC became very sluggish and took forever to start and the FSX would crash during loading, other programs would not respond and I figured it was something wrong that I had done. I tried loading default fail safe settings and it made no change. I tried everything I could think of and then went to make a coffee and chill out.Then I remebered the night before windows took a while to shutdown bacause it was installing Service Pack 1! That was it. That was the cause of all my problems :( I rolled back to a recovery i made the few days before and hey-presto. Everything is back and working.Im just glad it was windows that was screwd and not a hardware fault. Anyway its remined me not to fiddle with my settings now my system is totaly stable again (knock on wood). I do want to make a mirror of my entire harddrive onto my spare 750G WD drive but need a good program, any suggestions?PhewEver had a morning like that?

That's strange that SP1 made such a mess...I've had nothing similar happening to me on both the laptop and the desktop. Maybe you should report this possible bug to Microsoft, it might be a common problem with one of your components or something on this line.

Andysim - I have used Acronis True Image for a long time - (upgrading its version along the way). I currently use version 11 Home. The program has been updated since this version, but I have read conflicting reports of problems with the newer versions, so I stick with v. 11 Home. It has never failed me. I boot into Acronis from a startup CD that I had Acronis make.FYI: what I do is make a complete backup of my C drive (where I have FSX installed) - this backup is made to my D drive (then the backup is copied to an external drive). Then I copy just the FSX Directory to that same D Drive. That way, if I make a mess of FSX, I have the option of replacing just the files I messed up, or do a complete re-install of the OS (Win 7 64 bit) - this in turn replaces FSX with a "clean" working version.Sorry for the long "tome" about my backup.All best,Ray Landolt (Blackbird)

thats a good idea thanks for pointing that program out =).

I'm curious, how much did you actually mess with the RAM to try to fix it before you restored? On my motherboard, I have to manually set the timings, the divider, and voltages for the RAM otherwise the motherboard will load a much slower profile. Did you try this?

well my motherboard was in auto by default thats 1.50v. According to Kingston it should be 1.65v which is where I set it. Thats when it started playing up but as I said it was windows and not the ram. Its back at 1.50v now untill im 100% sure the system is stable again. I did not change any timings or anything else.
