I have bought a new SSD (Intel 520, 120 GB), and wanted to use this as my system disc. I removed the other harddisc, and installed the SSD with the newest firmware. And then Windows 7 I updated Windows 7 with no problems and then put back my old harddrive. I formatted that old harddrive just to clean up at the same time...

So at this stage everything was perfect. My new SSD was set as Master 0 Primary it boots on it and I have 1 TB emptyu harddrive I can use for whatever I want. So far no errors at all

Now here is the problem, I installed a few games and everytime I tried to play the computer would say Windows must restart because DCOM server process launcher service terminated, or it says Windows must now restart because the Plug and Play service terminated unexpectedly

Most commonly this error is caused by a rootkit virus, well I have tried formatting my entire computer, and running every antivirus I could find, so that shouldn't be it. I've also read somewhere it might happen when there are hardware issues.

That on the otherhand would make sense, as I just put in a new SSD. I don't expect you to know this error. I haven't found anyone who knew it yet. maybe you can me guide through what might have gone wrong when I placed in the SSD?

What have I checked regarding the SSD?

1. It displays the right name when the computer starts up
2. It has the newest firmware
3. Did a 'sfc /scannow' which told me everything was fine

I don't know what to do from here. Everything seems to work great with the drive. when I start playing games my computer crashes.
