Can an underpowered desktop(300watt power supply)cause sporadic problems or hang=ups?

it can do, i be set to it works, but you should proberly think going on for 450Watt for that sort of system the speakers really use a nominal amount of power from the computer though so don't worry



i love lights within a PC, i did it to the server at work, now everyone think I'm stange but they think the server is cool, ancestors!
no prob with power supply try formatting ur notebook bcos after 2yrs the m/b reduces it gig by 25% so its quite run of the mill
