Please help I dont know what could be wrong here. I recently upgraded to an Athlon 64 x 2 4400 processor and after I got the new motherboard in and everything working I have stumbled across a horrible problem when burning CD's. I couldnt seem to even read from my DVD drive. When I try to burn CDs/DVDs using Nero the progress indicator will get to a certain percentage and then stop. When I try to cancel out the program is frozen and all I can do to get out is disconnect my power supply for the computer. I thought it may be the DVD burner as it was about 3 years old so I bought a new one. Same problem except the DVD/CDs read now but wont burn. I have tried other burning packages which dont seem to freeze but always result in an unreadable CD. I detached the other DVD drive on the computer and upgraded the firmware for my new burner. Same problem. Could it be the drive is not getting enough power? All I have on the comp is a firewire PCI card, PCI express video card, internal HD and floppy. the burner and a fan controller. I think the PSU is 350W. I cant seem to find any problems that would make this happen! Please help.
