Hi all, First post!, hoping theres someone that can solve my problems. Basically the computer belongs to the other half, and shes had non stop grief with it since day one. The two major problems that are plaguing her at the moment: 1) She did a fresh install of Vista x64 and found (after a successful install) that she could only boot up with the DVD in the drive. No matter what boot sequence she tries, and we have attempted a windows repair (to which it says nothing is wrong). The PC simply will not boot up without the DVD. Instead we get a 'Disk boot error, insert system disk and press enter' message on start up. 2) She has a M2N-E SLi motherboard which seems to have unusual on board sound. The sound card comes up as a 'usb controller'. She often finds that the PC doesnt have sound or certain applications wont produce sound on the computer. After fresh install she hasnt had sound at all, and yes she has installed all the drivers for it. Also on top of that, the PC just seems to run pretty slow, its a 2.2 dual core machine with 4gb of RAM, so it should run fairly smoothly. This part isnt too important atm, she just wants it to work and Im out of ideas!. help!.
