Wish I'd read the post about the power supply. It destroyed my son's motherboard. It's a T4697. Emachines told me to replace it with their FIC VG33 which is a socket 478 Pentium 4 based on chipset Intel 845GE, FSB 400/533 MHz. Since my son has not backed up his music files, he could just replace it with the VG33 and everything should work. My question is, do I have to do that? There are some Intel boards that look like they might be better but I'm a real novice. This is an old machine and I don't want to spend a fortune. Do I get a new motherboard/CPU or can I just buy a new motherboard and use the old CPU. There's an Intel D845GEBV2 S478 533FSB DDR ATX A/V WB Intel Pentium 4 processor in a PGA478 socket with a 400/533 MHz system bus. It's only $59 from Hyper Microsystems. Is it okay or should I go for a better model. My son is a musician and his girlfriend does lots of graphics. Any recommendations would be appreciated. Eventually, we'll just have to upgrade to a better machine but for now I just want the thing to work.
