My girlfriend has a dell studio 1749 laptop. It has an intel I5 processor, and windows 7 64bit os. It has been crashing and giving us a clock interrupt message, I believe that it does it when it gets hot. I replaced the fan because i didnt think that it was kicking on (and because everything I read on the problem said to replace the fan). Alas, it is continuing to bsod on me citing the same clock interrupt error. I have reinstalled windows a few times so I dont believe it's an OS issue, and I have replaced the hard drives, so I think that is unlikely too. Also it seems that it only does it when i dont have my targus laptop fan under it, which makes me think it's a cooling issue.


Anyhelp would be appreciated!

I have a couple of suggestions. Feel the air coming out of the cooling vents, Is  the air hot?

Is the Fan really racing?

If the air coming out is not hot, Is there any hot spots that you can feel?

Link to the Dell service manual: ftp://ftp.dell.com/Manuals/all-products/esuprt_laptop/esuprt_studio_laptop/studio-1749_Service%20Manual_en-us.pdf

The reason I'm asking about the temperature of the air coming out the cooling vent is to see if the HeatPipes on the Heat sink assembly have failed.I have seen that in the past on other brands.


Since It does not do it when on the Targus, Is it possible that You are blocking the cooling air intake when it isn't on the Targus cooling Pad.


As a point of interest, I believe that the laptop should be shutting off if it overheats, not throwing a BSOD.

Is the laptop still under warranty?


I also checked Dell and they show

Dell Studio 1749 System BIOS, A08

Be aware that you can Kill Your laptop with a bad (Failed) BIOS update.  What version are you running?


Good Luck with Your Problem

I've heard some people have resolved this same issue by disabling power management software.


You could try installing Speedfan to determine if you have a heat issue



Or try BlueScreenView, it should give more details about the BSOD.
