In 1.4.2(i.e latest stable update), just starting a few days ago, the game would crash upon loading up any single world, either that or it would give the OOM error message.
Here's the crash log(it seems to be the same everytime):

--- END ERROR REPORT 4c92a4b8 ----------

I do know that running minecraft with more memory should solve this, but it happened all of a sudden for no apparent reason. My computer was also having some hiccups though, such as HL2.exe refusing to launch or just general lag and BSODs(reason for which was memory_management). However, when I get around to making a .bat file upon logging in it stays at Logging In and never does actually launch the game.

Are there any non-hardware related fixes for the above issues?
Thanks

Strangely enough tekkit runs smoothly, while stock minecraft crashes upon loading any world
Odd
