I'm know very little about computers so, if possible, keep to the simple language please
So, here's the situation.
My computer was connected to wireless internet and would randomly disconnect every few days, saying either "Acquiring Network address" or "Limited connection or No connectivity" The only way to solve this was to system restore my computer to a few days earlier.
Saturday evening, internet disconnected so i system restored to day earlier. This didn't work so i system restored to around 12 days earlier.
My computer is VERY slow, by the way so i had to leave it over night (128Mb of RAM <--LOL) In the morning i checked on it. I entered password, clicked OK, then had to leave for an NCO course.
Got back around 8 hours later, the computer was still on a blank black screen, with the cursor in the middle. Left it for half hour or so, tried moving the mouse, worked fine. Ctrl Alt Del, Nothing. Enter, nothing.
So i left it for another few hours and nothing so i turned computer off by power button on front of tower.
Now, when i turn it on it goes through the normal steps until i enter password at which it comes up with the message
"Explorer.EXE - Unable to locate component. -- This application has failed to start because urlmon.dll was not found. Re-installing the application may fix this problem"
I click OK, and then just a black screen with cursor in the middle.
Sorry for the long post, but i have no idea whatsoever, and would greatly appreciate any info on how to resolve this issue.
