Hi! I'm having trouble with a laptop. It crashes every now and then, and I can't find out why... It could crash with only firefox running, and then not restart within the 5 next minutes. Sometimes it just turns itself off, sometimes I get a blue screen. I suspect something like a memory problem. But sometimes the laptop just runs fine. What would you suggest? A memory check? Then how would I do that? I would attach a hijackthis report, but computing.net says I shouldn't if not asked to do so :) Thanks! /DT

Ooops, my title doesn't look the way I meant it... it's not so descriptive, sorry about that.

First I'd look at the Event Viewer and see if there are any weird errors.

Overheating is a common problem with laptops. Consider a cooler and/or a good cleaning: http://www.informationweek.com/stor...

Thanks for the tips so far! I'm not sure what you mean with the event viewer, bscott. I'll try to find out. I'll do a memory check tonight. When it comes to overheating, I thought of that, but this can happen even one minute after start up. But I think I'm onto something else now. The last blue screen I got complained about DRIVER_IRQL_NOT_LESS_OR_EQUAL and prisma00.sys. While I'm not sure what IRQL is, I think prisma00.sys has to do with the wlan drivers. I'll try that to and come back here. Thanks again!
