You should post which program is using the most amount of ram when the application error pops up.. I can't offer a suggestion otherwise, it would be bad form to suggest just buy a new one, when the fix is a simple one; finding the application that is giving you trouble. Unless you want a new one, and have the money, that's up to you.. Nothing wrong with doing that.

The graph and percent of CPU isn't usefull info at this time. As I mentioned previously, regarding the amount of memory being used up in the process/application tab. There's a list of files in the task manager, either "applications" or "processes" and to the right hand side it should show some numbers "not percent value" one of them should say percent CPU usage, the other one says a number of Kb or KB of memory being used.

It's important to note the application that is using the most amount of ram, as well as any other's that are using up lots, in the 50,000KB, to 100,000KB range or anything significatly over 12,000KB.. Also, note if the KB or Kb, is it Captital B or lower case b?

They represent two different multipliers in a numeric scheme, Caps B is BYTE, bigger etc.

I need to see those file names and the number of Kb or KB that they are using in order to make any further "VALID" suggestions regarding your issue..
