Dell Laptop external monitor = OK, attached monitor = BSOD

[jamesCantrell]

My old dell laptop L502x is a bit quirky and caused me to buy a desktop, however, i think it is still saveable. when i have it display to an external monitor via hdmi, it works 100% with no problems. however, when i use the monitor that is physically attached to the laptop, i will get a " A clock interrupt was not received on a secondary processor" BSOD. from what i've gathered over numerous crashes, i believe its a problem with the integrated graphics in the processor, since they are not used when outputting via hdmi. i could be wrong tho, any help is greatly appreciated.
