e6400 Sudden blue screens "irq not less than equal"

Hi,

My girlfriend has had a e6400 for just over two years. It shipped with Vista but now runs 7. It's been working perfectly until this week when it's started crashing with a blue screen and the "irq not less than equal" message.

Any ideas what could be causing this?

It is quite sporadic. It happens maybe once or twice a day. We've not been able to identify exactly what causes it. She spends most of her time browsing with firefox or using the laptop to stream/transcode video to our networked TV via DLNA.

Other than a complete reinstall is there anything I can try to fix the problem? Or is it likely to be a warranty issue?

Thanks!

 

Did you install any software, or new hardware? Those are usual suspects.

You also could try F8 and repair my computer and see if start up repair finds anything.

 

Probably driver or hardware issue. Search Google for how to use WinDbg to analyze kernel memory dumps. Below nice instructions on how to perform that.

 

I would check the integrity of the file system using chkdsk. And test the memory... just boot and run the Dell Diagnostics CD or perhaps diagnostics in the BIOS.

Could also purge browser temp files.

Could be software, or could be a hardware fault/warranty issue.

Driver problem, Bad RAM or possibly overheating CPU are possibilities. The rest of the BSOD message may give a clue.

that happened to me too, mine is a Latitude E6410. tried everything (chkdsk, sfc etc.) w/o success. then I saw on my security log a lot of audit failures regarding ipoint.exe (Intellipoint Mouse software). uninstalled it completely and then reinstalled. seems stable now.
