Launcher.exe............ok lets put that aside for the moment, it may be legit. Will investigate that further.
You security prog. has given a clean bill of health so it possibly nothing to worry about.
RAM...........you have a most peculiar ram setup installed. 1300ks hmmm. As has been said, RAM comes in increments of 516ks so 1300 does not add up. Perhaps one of the ram modules is faulty.
A new matched set of modules giving 2gb. can be had for about £35 upwards depending on the type required by the motherboard, and is a doddle to install.
That might be worth considering.........your system is creaking at the seams as far as resources go........1300 ram installed, 50 processes and 728k of ram just to keep the system going.........leaving only 547 to play with. Open up Firefox with two or three open tabs and bang goes another 200/250 and you are beginning to get to the "out of resources" stage.
A ram upgrade is recommended.........going up to 2Gb installed will instantly give 700k more to play with and solve the problem. Or, use a lighter browser and/or av prog.
I bet you wished you had never asked the question
Will be back........and don't worry too much, the system has been coping for a while as it is and the error report you had was a rarity, a one off due to the circumstances of multi-tasking at that time. But more ram would offer peace of mind.
