New built PC unable to use 64bit Linux

I just built an AMD A8-3850 APU on TA75M MB with 8GB PC3 Seagate Barracuda 1TB and LG DVD/CD/RW [suppose to be cd+- and DVD+- compatible]. I can download and burn 64bit Distros
{so far only using CD-R and DVD-R} with it [this applies to any 64 bit Distro whether burned on this machine or another] but when it comes to using them, whether Live or install, my monitor screen goes black almost immediately after choosing either Live or Install. The Optical and hard drives can be heard working and after a while the Live session plays desktop music but still no display. The install choice just stops because I'm unable to see progress [due to no display] and input choices to keep it going because monitor screen is black. The only think I can think of is Optical drive is somehow not functioning properly. So far I've only tried it with VGA output and both VGA and DVI to HDMI cables connected. I need to try it with just DVI connected. While installing H.S.Fan I did hear some ratcheting crunching sounds quite similar to what you get when putting HeatSink on backwards.
Now WindowsXP-64bit seemed to install o.k. but painfully slow. However I may only run this in a VM later on. I did get Ubuntu 10.10 32bit to display in live session and Trisquel5 32bit to display Live and install. I've looked in bios for settings that might apply but did not recognize any. Well thanx if you can help shed light here!

its a display issue

"The Optical and hard drives can be heard working and after a while the Live session plays desktop music but still no display."

Sounds to me like your install and computer is functioning properly with the exception of the display. I'd focus your troubleshooting here. See if there is an updated bios for your video adaptor. try a different video adaptor or monitor.

Video modes may be detected improperly

Since Ubuntu 10.10 32 bit will display in Live session, I would also point to a problem with the Distro not properly detecting your video subsystem and/or monitor EDID. I have the same problem in 32 bit with the new 3.x kernel and ATI Radeon Express video subsystem which I was able to 'fix' by using the nomodeset kernel mode option and selecting the video resolution later in the process. You can add the kernel option on a Live CD by pushing the F6 key (other options) or typing the option at the end of the kernel boot line after choosing to edit the GRUB menu line.

You may also choose to use vga=773 after the nomodeset option. The 773 specifies 256 bit color @ 1024x768 VESA mode chosen from the Wikipedia article http://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers

"it's a display issue"

"I'd focus your troubleshooting here. See if there is an updated bios for your video adaptor. try a different video adaptor or monitor." *~Adapter~*

The Video is on the APU aka CPU+video on same chip under heat~sink~fan in MB socket....
If it were a function of BIOS then Biostar or AMI need to get it done I think???
I'm confused now I thought it was that Linux drivers had not been produced for this hardware yet and therefore not fully functional with Linux yet? Hope someone more able than I gets these drivers written soon.
Is it possible to update video BIOS without having a display on screen. Apologize for ignorance here I have dementia and very slow sometimes.

"Video modes may be detected improperly"

Thanx for your effort and time....
Since writing this and trying different BIOS settings I cannot get any Distro version to display live or install. I have yet to figure out how to do what you wrote. Mostly because of memory and concentration problems and time restrictions. If you care to write some explanations of what and how to do it it would be greatly appreciated. I really cannot perform in command line unless it is copy and paste due to dementia Having a GUI helps keep me able to use a computer.
Yet I'm having a devil of a time getting WindowsXP64 registered and configured...
I'm only going there to verify hardware...
I need Ubuntu back~ ~ ~ ~ Windows cracks me!!!
