    I purchased some upgrades for this computer below:
    HP Pavilion a6113w Tower
    - Intel Pentium Dual Core E2140 @ 1.6 GHz
    - 400 GB HDD
    - 2 GB RAM
    - DVD+\-RW
    - Integrated Graphics
    - Windows Vista Home Premium 32 Bit which were a ATI Radeon HD 4850 Video Card and a Roswell 750w Power Supply. Worked great for the first 8 hours crashed for about 3 hours worked again for another 6 hours then crashed again and i cant get it to come back on. power supply is working for all i know and the video card hums on for a second when i try to reboot so i figure it is woking. i have even gone as far as to take out the video card just in case and still unresponsive. . Can anyone help?

    PS I tried putting the other power supply back in and it worked fine but i can't use the Video Card w/ that power supply..

    I'd restore the machine to the original configuration and see if you can get that working first.

    While a 750 watt power supply should be plenty for that video card, Roswill power supplies are very low quality. My best guess is that your PSU is not up to the job and Rosewill supplies are known for that. See if you can borrow another more powerful supply than your old one and try it in there.
