X61S BSOD on router restarts

[HipHoper]

Hello and Happy new year !!!

Got a new X61S with xp pro for this client few days ago, And he complains that he has some problem with his ADSL router at the office, Which he needs to restart from time to time. He also said that every time he restart the router the X61S gives him BSOD. He also mentioned his computer restared itself when he connected his USB printer at home - But that mught be a USB voltage shortcut issue that doesn't bother me much.
I worked on this computer before giving it to him for few hours while installing and few hours in his office and it looks stable.
There is only OUTLOOK 2007 and IE7 that are active when he's having these BSOD problems.
I asked him to take care of the router's problem, And see if it persists.
Are there any other things I can check (Some Dr. Watson logs or such), To see what's the reason of the BSOD ?

Thanks for the link OMG. Saw the F1 test thingy, I think I will run memtest or something like that if problems reoccur
