hi i have a brand new windows xp and already there are things wrong with it. i get this message after being on the computer that says i have low memory (Windows - Virtual Memory Minimum Too Low. Your system is ow on virtual memory. Windows is increasing the size of your virtual memory paging file....etc) but i've only used 5.05 gb out of 67.9 gb . also, when i start my computer i get this bridge.dll error. i downloaded the hijackthis and here is my log. it'd be great if someone helped me out step by step cause i'm 16 and i don't know anything about computers =). thank you.
