your pc should be fine to multitask

i got athlon1700xp 512ddr

i download,surf net,burn dvdr on fly,and burn cd on usb writer all at same time ,np at all

i would say your problem is laser related,the problem u got is ritek g03 are best readable media i have found

first try cleaning your laser u be surprised how much this helps

if u still got the problems then i say your laser needs adjusting and most likely replacing
