Dell XPS 720 - Installing Windows 7 doomed my PC.

Please help, i'm not sure what to do.

Installing Windows 7 has seemed to doom my PC. Everything was running fine on my XPS when I decided to install Windows 7....

They warn you that during the installation your PC will need to reboot itself a few times.. while the installation was running it tried to do the first reboot and when the computer came back on it stayed stuck on the first screen...

" Dell  ...  Dell XPS720 ... Bios Revision A06 " with a progress bar that freezes at about 1/4th of the way.

There's nothing I can do about this screen, after about 3 hours of sitting there I decided I would try a reboot, I forced the computer to turn off and when I turned it back on it just got to the same point (takes about 5 seconds) and it froze at the same spot.

Any experts know what might be going on here?

    Well it isn't making it past POST (Power On Self Test) by the sounds of things.
    First remove all power sources as unplug your PC from the wall for atleast 10 seconds this lets the capacitors discharge.
    Plug back in and power up is it working?

    Try this next/
    I would try removing your first stick of RAM.
    If it boots fine then you are holding a faulty stick...
    If that fails replace the RAM and remove the next to work on a process of elimination.

    I would proceed to test the power supply.
    and the Graphics etc.
    RAM tends to be a bit more common in my experience, and discharging the capacitors can help but indicated that a hardware component may be on the way out...

    RAM problems - Typically screen halts
    Graphics         -     "             "           "
    Power Supply - Typically causes reboots and black screens
    Mainboard - any of the above.
    This is a rough guide and experiences can be much more random, if under warranty get Dell to sort it out?

    have you check the compatibility of your hardware whether it has been accepted to install win 7? some of old model have not supported with the win7 installation because win7 need to have high processor with higher ram.

    if you want to install win 7, tried to do image on win 7 by virtualization. use vmware workstation to create image on win7 and run on vmware player to run image on win 7/

    hopefully it helps

    I can't thank you enough, i've done what you said and removing a stick of ram has worked perfectly.

    What's weird is the computer boots properly even when i've added it back in.

    I would suggest that the windows install and your computer breaking is a coincidence if it won't get past POST.
    Perserve Windows 7 is great and your PC has more than enough grunt to hangle it!
    Good luck!
