I am a newbie to the computer building hobby so please bare with me. I have recently put together what is meant to be a media center when I get all the kinks worked out. It consists of an Antec 650W PS, an Abit F190HD mobo, an Intel Core 2 Duo E6550 (2.33 GHz) CPU, 2 GB Kingston RAM, a Liteon on DVD RW and a Seagate 750 GB HD. The assembly went off without a hitch, but the system setup has been a bit hairy. First off, every time I shut down the computer (whether it be from the BIOS or the OS) it will not restart. All I get after powering back on is a black screen. The only remedy is to disconnect all power, wait, then reconnect, and power on (annoying, but nothing serious). The real problem is that after installing the OS (XP Pro) and the mobo drivers, the computer doesn't even last 5 minutes after boot up before freezing (hard shut down is only escape). I did not have this problem before installing all the HD audio and video drivers that accompany the mobo. Just looking for some advice and hoping the hardware purchases I made were adequate to support the HD outputs. Thanks for any help.

could u please give us what u built it out of (precise parts).
