Weeeeell it seems my mom wanted me to install a USB 2.0 PCI Card, but when I was installing it, I kept on getting Error 10, and that resulted in atleast an hour of time wasted due to reinstalling the driver and rebootings. Then I googles the error and drew the conclusion that the power supply is growing a tad too old, and this assumption was backed up by recent troubles with mice (mouses? nousei?) and keyboards (most of the mice and keyboards worked on my PC but not hers for some reason >_>;;)
Anyway, to get straight to the question, are power supplies replaceable fairly easily, as in plug-n-play easy or do they require a bit more to replace em (as in they have to work with the motherboard and all that fun stuff)?
