LJ help? :-(

[sigune]

There's something funny (but not amusing, alas) going on: LJ loads extremely slowly for me. The strange thing is that it's only LJ that does this (even deviantART is quick, compared to it) and it does not happen on my office computer, where LJ behaves normally.

Does anybody have any idea about the how or why, and what I might do to remedy it?
(I've already cleaned out my temporary internet files, and checked whether the computer needs defragmenting, which it doesnt. Hm.)
