can not boot no live distro at all anymore!

I use to be able to try all kind of live distro but the last one that did boot was sabayon live cd mini edition. after that any that would normaly work fine dont any more?.Any tips on what happen? most just stop loading exemple: pc linux os minime 2008 in verbose will stop just after the time an date setting in the step; configuring kernel environement.Nb: windows XP still work fine on that PC. other distro like Knoppix,Elive sabayon dvd latest stable will start scrolling all sorts of errors after a certain amont of progress and it scrool so fast I dont even have time to read one. My system is an MB ASUS a7v-e, amd duron 1300mhz,512 mb ram.

no still no luck, on every distro i tried safe boot and or with extra hardware detection and video were detected fine, I will try with an other set of RAM in case there is a small defect that ocur and that very specific adress is require to any linux distro to load properly.

I have a regular DVD-rom drive and a DVD-burner and same result on both so I dought that it would be a dirty lens.

same burned copies that was working previously on my system dont work now but do work on others systems that i use at work. So nothing wronh with the cds what ever the distro used. [Modified by: didilalala on August 11, 2008 05:26 PM]

[/quote] I had a problem with CDs/DVDs not always working in the DVD drive I have. Turned out it was a bad IDE/PATA cable. Try swapping the cable out for a new one or one that you know is fine. Mine had a connector that separated from the cable, but it's possible to have a break in the wire(s) sometimes.

There's a couple of things to check before you go and replace the cable. 1) Do either of the drives work OK in XP ? 2) If they do, have you checked your BIOS to see if it's still set to boot from CD *before* the Hard Drive ? (It may have been set to before, but I've come across a system randomly changing it over night) - the usual ways into the BIOS are to press either the Delete key, F2 or F6, when the system first powers on (though it might be different for you, it should say at the bottom what button to press to get to "Setup"). As an aside, if Windows XP works fine, it's unlikely to be dodgy RAM (XP would've been crashing/BSOD'ing by now if that was the case). Penguin

Linux live either boots from cd or it doesn't. It doesn't work 1 sec. and then not work again later. Something has been changed. Did you read Shashank Sharmas post about live cds not being able to change computer settings or hardware and have you tried the dmesg suggestion?
