Everytime i open LimeWire it works perfectly, i can connect and download files but after about 5mintues my computer screen goes black and my monitor picks up no signal, it thinks my computer is in some kind of hibernation mode and comes up with that little box saying monitor stand by. I can tell my pc is on as the coolermaster dials are lit up and my keyboard and mouse reciever blicks as i bash the keyboard and move the mouse.

I have Windows Home Edition SP2, AMD ATHLON 3400+, 200GB Hard Drive, 1GB RAM, ATI 256MB 9800 PRO. If it helps.
