    Hey guys, I can't figure this out for the life of me.

    A week ago I installed my new 7800GT and everything was fine for about 10 minutes, then programs started crashing and the computer would stutter, and take forever to install small programs. I reinstalled windows XP after a "quick" NTFS format of my hard drive.

    The problem was still there and the computer was barely usable. I installed my old 5600 256MB nVidia card and most of the problems went away, but not all. So I ordered a new PSU with higher amperage and wattage. That seemed to make running the 7800GT about the same stability as with my 5600 256MB.

    Now I am stuck with stuttering sound and video, even though I tried two different sound cards. I have tried different drivers for my CPU, chipset, VGA, Soundcard, etc with no results.

    I did have my CPU overclocked from 2.2ghz to 2.37 but Prime95 only got the temps up to 44*C after 4+hours, and the problems are there no matter what clock speed I try (within reason). Also tried memtest86 with no errors reported.

    System specs:
    A64 3500+ Venice
    ASrock ULi Dual SATA mobo
    xfx nVidia 7800GT
    Rosewill 450W Dual 12V rail PSU
    2GB PQI Turbo Ram
    WD 250Gig + Maxtor 120Gig IDE HDs
    ALC850 onboard sound or Sound Blaster Live! 5.1

    Help! I hope it isn't a hardware problem.
