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!

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.

scroll down to the prebuilt versions to download either the ISO file for CD or the zip file for a floppy or the zip file for a flashdrive(USB)

Overheating is a common problem with laptops. Consider a cooler and/or a good cleaning:

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!
