I'm having a problem with my wife's Acer laptop.
It randomly closes windows/applications with no error message, it gives "out of memory" errors, usually while using Firefox, after which it won't open up the task manager/Windows Explorer, and all programs close on their own frequently after the first time. This is fixed after a reboot.
When you can open task manager, it says there's 3+GB of memory, even though there's only actually 1.5GB installed
I ran malwarebytes, and it came up with nothing.
My current suspicion is that it's a bad RAM stick (there's two, a 512MB and a 1GB), but I'm wondering if there's something I may be overlooking that could be causing the problem before I go taking it apart.
