Problem: machine starts booting, fan start spinning fast, machine shuts down.

From what I have seen this overheating problem is, sadly, a VERY common problem with XPS M1330: very disappointing of dell not to fix it properly.

Needless to say, warranty has expired. So, provided a motherboard replacement works, where can I repair this machine for a cost that is not large, given this is a 2007 laptop?

Thanks.
