Could well be the cable if it is an intermittent problem. There are heaps of people who seem to be suffering from an 8 beep post...check your bios settings and make sure "non-turbo flex" is disabled. Google it, there is a good post on the Dell community forum.

Good luck

I have the P151SM1 and it's pretty loud even on idle. But my problem is really that the temperature keeps rising for some reason' date=' forcing the fans to turn up. Then it'll turn down when it's cooler, then it gets hot again.....never-ending cycle.[/quote']

Sounds like it needs a clean and a repaste, that is assuming it gets hot again quickly. What max temps are you seeing?
