I have a problem but first here is my background info.
PC - Mesh computers
Windows XP Home (legitimate licensed version)
Nvidia Geforce 7950 GX2 1GB Dual card.
Norton Internet Security 2007(out of subscription but only just finished that annoying reminder countdown thing at the same time as the problem occurred)
I have been reading through all the different postings regarding this error message on various different forums and following various bits of advice has not helped.
This is really long winded so please stay with me.
Just after Christmas my PC developed a problem, upon start up it would get to the windows splash screen and then go black and switch between a black screen and an off screen (which is also black if you see what I mean). It would stay there doing this and progress no further. I was able to load up in safe mode, with networking (giving me access to the net). I reviewed various online postings to see what the problem was, this led me to viewing the event log to see what error was recorded by the computer. It is as follows...
Type: Event ID 10020, Source: DCOM
Description: The machine wide default launch and activation security descriptor is invalid. It contains access control entries with permissions that are invalid. The requested action was therefore not performed. This security permission can be corrected using the component services administrative tool.
I load up the component services administrative tool and navigate to 'computer' in order to adjust the settings but when I click on 'computer' it force closes and disappears.
If I try to load up using the last known good configuration it does the same black screen thing as before, starting windows normally does not work either, I just get the same problem. I have managed to install the latest driver for my graphics card, but with no change to the problem.
So to summarise this is where I am...
Upon start-up I get to the windows splash screen and the screen goes black.
I can restart and load in safe mode or safe mode with networking (although networking (internet)doesn't work)
Starting up using the last known good configuration does not work.
I cannot use system restore in safe mode.
The Component Services Administrative Tool opens but force closes when I click on 'computer'
Help and support does not work either.
I hope someone can help, thanking you please.
