hi, i've been having a weird computer problem since yesterday.

i need major help..! the trouble started & happens after every internet connection. after connecting to the internet, everything (browsers, applications, drives, commandprompt, etc.) works fine, but after 15 or more minutes my computer starts to slow down, connection starts to lag, like the machine is not functioning at all. i couldn't open any application, program, my computer & even the window task manager. the only folders i could open is in the ones on my desktop. nothing happens when i type "ipconfig" in the command prompt, "ping" also fails sometimes. when i open "my computer" nothing is shown except the animated flashlight, it just kept on browsing & searching, and it'll never end, like it is stuck or something. i couldn't open the "window task manager" as well, i kept pressing ctrl+alt+delete, but nothing happens.

i could only access the programs that i've already openned before the slow down occured. but the programs doesn't function.. like with internet explorer i could scroll up & down, i could click links, click the toolbar icons, etc. but the program doesn't function. all i could do is restart my computer.

i couldn't shutdown or restart my computer properly from the start menu. the only thing i could do is push the shutdown or restart button. also couldn't disconnect from the internet or even check the status.

and the problem occurs much faster (about lessthan 10 minutes) when i'm downloading with or when azureus is openned. azureus will start out okay then after lessthan 10 minutes, azureus will stop functioning. it'll stop downloading & seeding. then the status will all turn red. i could still access azureus but it'll not function or it'll not do anything.

the good thing is i didn't encounter this problem when i'm offline or not connected to the internet.

really need help.. this is really urgent. what should i do...? what causes this? hope somebody could help me out.

by the way, i'm using windows XP, dsl connection about 1mbps, processor is athlon xp 1.7, 2 LAN cards : ADMtek & VIA Rhine.
