I am using Ubuntu 12.04 with windows dual boot(no wubi is used)(on startup purple color screen with option of Ubuntu and windows).
Alloted disk Space to Ubuntu-20GB
Laptop Used-Dell Studio 15 RAM 4gb ATI Radeon 0.5 gb
Initially it was running fine but now its getting shutdown automatically.And even the shutdown is not proper.The screen just turns black suddenly.
And its not a heating problem.Even if no program are open that can eat memory the problem is there.
I have allocated full RAM(4gb) to ubuntu.
Should I allocate more disk space?If yes,how much?
