login screen freeze

[elny3680]

i am having problems switching between accounts...if i am logged in & try to switch (windows button + L or switch normally) to a guest account or if my brothers switch to their account while i am logged in, the computer freezes. it does that on everyone else's accounts also so it doesnt affect my account only. but if we log off first, then log in to another account then everything is fine & dandy. does anyone know what is wrong with my computer? do i not have enough memory? i didnt overclock the processor & i havent upgraded the firmware for the mobo.

these are my specs on the pc

windows xp service pack 1
abit nf7-s
ocz 2x256mb ddr400
athlon xp 2500 barton
wd 120gb 8mb
wd 80 gb 8mb secondary

are you having any other problems with your machine? is it running applications and games just fine? i wanna say it may be a memory thing. try running memtest or maybe something in your windows is just messed up. try repairing it. that should get you started.

everything runs fine...its just the windows login...i really dont want to have to reformat to fix this...but im starting to backup everything in case...any other suggestions?
