Just got an XPS 8500 (i7, Nvidia, 12 GB RAM). works great. One issue though. Twice the computer has suddenly started producing a clicking sound. Makes me thing something is loose. But it's only done this on two occasions in the two weeks we've had it. The rest of the time it is noise free.
Both times I tried shutting down the computer - the first time it did eventually shut down but took a few minutes rather than instantaneously shutting down which it does otherwise. The second time this happened after 5 minutes the computer had still not shut down and I did a manual shutoff.
Both times the computer had been on a significant amount of time, though most of that time it was in sleep mode. Each time this happened, I wasn't really taxing the system - I was just reading a web page, no fancy graphics or video going on.
Thoughts? Anyone else have this problem?
