Computer will not boot up, black screen.

[Emanual4real]

HP p6130y, AMD Phenom X49750 quad processor, 8gb ram (original), ATI Radeon HD 6450 (upgrade), windows 7 x64 (upgrade)

Originally had freezing problem when I first upgraded to Windows 7. Was able to fix it via these threads (can't remember how). It started freezing up recently, particularly after loss of power or sleep/hibernation. Format hdd, reinstalled windows 7, started freezing up randomly. Tried to install Vista x64 from cd, started freezing during installation. So figure it's hardware. Removed video card, can't get anything from onboard video card to show up, vga or dvi. Powers on to a blackscreen. (both cables work fine with an alternate computer)

I could reinstall the video card and I may/may not get it the boot up screen, but what can I do about the freezing issue?

Any help is appreciated.
Thanks in advance.

find your motherboard manual online and figure out how to reset the bios, or just remove the motherboard battery AND unplug your power supply for 30 seconds. This will hopefully allow the onboard video to work. Then reflash your bios, since yours may be corrupted right now. If these do not cause the freezing to stop, you have a hardware problem. Either a bad hard drive, motherboard, or power supply are possible.

Thanks for the help.

I reset the bios. Found the updated bios on hp's website, but the only directions were to open the file (as if the system was working). Still no onboard video.

in bios under "advanced" tab check "device options" and make sure that integrated video is enabled

I recommend you reflash your bios, even if your bios says its current
