Strange problems booting Knoppix Linux....


Ok here's the deal, I am currently running a HP a220n desktop machine (with stock mx703 monitor) which was recently upgraded with a 160GB 7200 RPM Western Digital hard drive, and a MadDog Multimedia 16x Double Layer DVD burner(16XDVD9A2) as well as a MadDog SurePower 350W(400W max) power supply to support the new devices.

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.


[NOTE - I posted this same topic at another forum, thought I would post here to increase the chance of an answer, if that is at all possible - the original thread is located at linuxcompatible.org

Nope, as I say, I have tried different combinations of cheat codes, and they have made little difference. Thanks for the help just the same.

Well, If you have tried other Live Distros with the same result then I would not say it is knoppix. I don't see how any of the hardware you installed would have the effect your discribing. I would say it has to be a bios issue somewhere...
