Constant blue screens on startup

[MattR]

My XP laptop at work is sick, on startup, if I open too much too soon, normally Chrome with a load of tabs saved from last time, it blue screens and dies. It only happens when it's recently been started, I can have 20+ tabs open in Chrome and loads of other crap open after the laptop's been running for an hour and it'll be fine, but that would crash it instantly at startup. If I open up smaller programs like Notepad++ and FTP and let it 'warm up' for a bit then everything'll be fine.

Obviously I assume it's bad RAM but does anyone know of anything else that might cause it??
