Computer Help Please!

[Mr Rat]

-896Mb Ram? Are you supposed to have a gig of ram?
-Virtual memory issues...see if any of this helps:

-Have you checked task manager and sorted by CPU to see if anything is hogging resources...then sort by memory to see what is a RAM hog
-Go to msconfig and stop all unnecessary programs from starting
-Get the actual error message you are getting and post that

Not sure if these will help...post a hijackthis log as funkyworms suggested also.
