Slow computer after installing network

I recently installed a wireless router (D-link DIR 655) with wireless
connections to a laptop and printer (Canon Pixma 980) and wired connections
to two desktop computers. All three computers are running WinXP Pro SP2.

One of the desktop computers began to take an inordinate amount of time to
process even a simple screen refresh. Subsequently, I noticed that any
activity on that computer is accompanied by rapid flashing of the
corresponding connection on the router. (This does not happen with the other
wired desktop.)

I've begun to suspect that the problematic desktop "talking to itself" via
the router.

Any suggestions would be most appreciated.

Sounds more like virus/spyware issue, if related to just the one PC - have
you run a scan?
Cheers,
Jim

Frequently the reason for slow opening of Explorer windows is that a mapped
drive is inaccessible. When any Explorer window opens, the drive letters are
enumerated 'just in case' it's necessary to show their content.

Desktop is actually a special Explorer window, so the same applies.

First thing to check:

Though, this means that in a workgroup situation any computer which shares
folders cannot be turned off during work, because of the problems this will
cause if the share is mapped elsewhere. Windows 7 still has this issue.
