this is my 1st post so i hope i can explain this right.i have vista32 home premium with 4gigs of memory.this happens a few times a week when im on here.all of the sudden my browser freezes up.in other words i cant click on anything.i have to shut it down just to get it to work again.i notice when i was shutting it down there was a runtime error saying low memory.now i have memory meter and it says i have 2100mb free but something telling the computer that i dont have any memory.idk if that makes any sense or not but i hope you can help me with this.ps i have a belkin router and my son uses my laptop the same time im on here.but not sure if that would be an issue or not,thank you.
