problems with HP a220n/monitor and Knoppix....

Before the upgrade, when we were using the stock power supply and stock components, Knoppix Linux worked fine, detected all components fine and everything, but now, for some reason, right after it has set all the device settings, and where it usually clicks and displays the OS component loading screen, the monitor displays the "entering power saving mode" screen. I have tried different command line options to varying degrees of success, with "VGA=normal", it manages to load into the desktop, sees all the drives and everything, but just as I am about to enter an URL into Mozilla, the monitor clicks and goes into power saving mode. Now, the very first time I used Knoppix after the upgrade, I was actually able to use it for like 10 minutes before it clicked into power saving mode...which I don't believe it is actually in, as in Windows the system LED actually flashes when it is in low power mode, and even though the monitor LED is orange, I can still see the CD status light going and the drive is still humming, and the system LED is solid. I don't understand why it would work fine with the old power supply (which was found to be defective when tested with a power supply tester), and now it refuses. All the new components are recognized and work to their fullest capacity in Windows XP, and the power supply and low power modes work as expected in Windows XP. I even turned off all power saving modes in the BIOS to no avail.
I have tried several different LiveCD distros, with the same results, I have tried numerous resolution changes and other command line options with little effect...I am really at my wits end here, I enjoy using Knoppix, but I am ready to give up...this is very frustrating. Any help you could provide would be GREATLY appreciated.
My system Specs are as follows:
System Model: HP Pavilion a220n with Pavilion mx703 monitor
(nForce 2 chipset with integrated sound, video(disabled) and network card)
RAM: 768MB
Video(Integrated GF4MX has been disabled):PNY GeForce FX 5200 128MB
Hard Drives: Seagate 120GB 5400 RPM(stock), Western Digital 160GB 7200 RPM (upgrade)
Optical Drives: JLMS DVD-ROM Drive(stock), MadDog Multimedia 16x Double Layer DVD burner(16XDVD9A2) (upgrade)
+DSL modem, printer etc. (not really relevant, but I felt compelled to include them)
Thanks in advance for any help you can provide, and I apologize for the length of this post, but in this case, I felt elaboration was necessary.

You already went through the cheat codes that you can execute at booting under knoppix.
I would suggest booting up your PC with the Knoppix liveCD and see if this problem still happens with the liveCD running. If it doesn't happen, then you could try replacing your current XF86Config-4 with the one that the liveCD provides. This file is on /etc/X11/XF86Config-4. It will be located on the hardrive where your current knoppix installation is, and also in the temp drive of the knoppix liveCD, so bring the one from the temp drive (liveCD) onto your knoppix hardrive. It is worth the tried.
Also, try opening up your current XF86Config-4 file and make sure the right monitor with its appropriate model, horizontal sync, and vertical sync are listed there. It might be that you need to tell knoppix the right monitor name, model, and its settings for it to work properly.
There's also another program called "xvidtune" which you might be able to use and tune up your monitor.
Don't give up. I'm sure it can be fixed. If knoppix is working perfecly fine, then it's just a matter a figuring out your video card. My answer may not be the best...but I hope some else in here will give the right answer.
Good luck and hang in there! and keep this thread going if you still having problems. I'm sure someone else will respond.

Are you still having the same problem after booting with the older version on knoppix liveCD?
What other liveCDs have you tried?...just curious, but it is odd that your monitor will go into stand by mode after a few minutes since the monitor is plugged into a power surge, or a UPS, or a regular outlet to simply get its electrical power, and plugged into the video card of your computer to receive signals to project images from your PC. The power supply on your PC is simply providing power to your Hard drives, motherboard, cpu, cd-roms, etc. inside your PC. I have a hunch that's telling me that this doesn't have to do with your PC's power unit. The only scenario that I can think of me dealing with power units is when I would have to many pieces of hardware connect to it and one of the hardrives would go offline because of over heating, but then again you said this doesn't happen when you PC is running under windows, right?

The dvd drive. Is it the only cdrom/dvd drive in the system, or did you add the dvd drive to the hardware senario (the old cdrom/cdrw drive is still present in the system)?

Yes, neither the older previously working version or the latest build work anymore. I have tried Byzantine OS and Gentoo, both with the same results. I am an intermediate Windows user - pretty savvy, but I'm not going to be cracking system files, and I know little to nothing about Linux, which is why Knoppix Linux was so intriguing to me.
The added components work fine in Windows XP (pre-installed), have had no problems, and the power supply was tested with a tester and checked out. I had my doubts about the power supply, but it is so odd, and since the LiveCD worked fine with the stock power supply, and the new components are seen fine in Windows, I just figured it's a case of Knoppix not liking/not properly configuring the power supply. I have tried running with PNPbios=off, and all power settings off etc. and it has made absolutely no difference. I have a suspicion this is some issue with HP proprietary components, that's the only thing I can think of...it should work, my components are fairly standard as you can see, not exotic or outdated. The computer initially came with a DVD-ROM drive and a CD-RW drive, after we got the DL DVD burner, it replaced the CD-RW drive. I appreciate the help.

Is your PCs power unit one of those that it is supposed to interact with the OS. That can't be it. Power units jut provide power and that's about it. I'm puzzled to what could trigger your PC go into stand by mode.
What do you think Danleff? Hopefully the other guys in here will come up with a better solution for you.

When you burned the Knoppix cd, what speed did you burn it at? Did you use a cdrw disk or cd-r disk?
And I assume that you can't resume the monitor suspend by moving the mouse, or hitting the space bar on the keyboard?

All that I can say, is that different cdrw/cdrom drives have trouble reading the tracks, if the cd disk is burned too fast.
This happens a lot on some laptop cdrom drives. My 24X cdrom on my laptop would not read burned cd disks, but I switched out to a 20X and it worked fine. One would think that the faster (newer) drive would read the disk correctly, but it does not.
try getting into a terminal window and typing in dmesg.
See if you get a message about a seek error of some sort on the cdrom drive, which should appear at the bottom of the output of dmesg.
Look at my guide, located here.

I ran a complete array of system tests with the included PC Doctor diagnostic software - every test passed, so there is absolutely nothing wrong with my video card or monitor or any other devices.
Tried to boot the older, previously working CD again just for the hell of it - same results, surprise, surprise. Anyway...I collected my BIOS settings if they can be any help. Hopefully somebody can shed some light on this strange problem....
Main Settings:
Plug and Play OS = Yes
Primary Video Adapter = AGP/Onboard
Local Bus IDE Adapter = Both
USB Legacy Mode Support = Auto
Onboard LAN = Enabled
Onboard LAN Boot ROM = Disabled
Onboard Audio = Auto
Onboard 1394 = Enabled
Power Settings (I did change all settings to disabled with no effect):
After AC Power Loss = Power On (alternate options = Stay Off/Auto)
APIC = Enabled
S3 = Enabled
Boot Device Priority -
1. JLMS DVD-ROM
2. Seagate Hard Drive
3. Floppy Drive

Sometimes if I can't get an answer in a forum, I will post it in another one. Hang in there man.

Let us know if you succeeded. I love to hear what was the problem.

If it does not, think about the power supply not handling the load. Those 160 gig hard drives take a little juice, also.
If it works OK, I would suspect a faulty new Mad Dog drive.
How is the dvd drive currently jumpered? Primary, seconday, master, slave, cable select?
If you have Windows installed, is the drive working properly otherwise reading data media?

I appreciate the help, but unfortunately, all drives work fine in Windows as does power saving mode - the MadDog drive is the second drive on the secondary IDE channel, replacing the old stock CDRW drive. And on the rare occasion when Knoppix does decide to boot (albeit very briefly before deciding to incite more of my rage and go into that endless standby) - I can actually see all the HD and Optical drive icons on the desktop - so it sees them fine. I can't figure out why this is happening, it really makes no sense. It sucks even more, because I have tried different combinations, and sometimes it boots and stays on for a little longer, and I get my hopes up and THEN the monitor clicks into standby - changing power settings in the control panel makes no diff (in fact, last time, they were disabled by default). I had posted this problem at Knoppix.net, but all suggestions were command-line, and had little effect. Perhaps Knoppix does not like my power supply, or does not like the combo of my particular monitor and a non-stock power supply (though the monitor is identified correctly by ddc)I know that seems ludicrous, but that's all I can think of. I appreciate the help.

I don't remember if Knoppix gives you the ability to add boot options. If so, try adding acpi=off to the command line (or if it is a menu boot option). If it is a menu option, it may be noapic.
