Fedora 10 hangs after some time it stops responding. To restart power button has to be reset.My laptop config is 64 bit AMD processor AMD TURION (integrated on motherboard)graphics card.
I am unable to install xampp 1.7.1/1.7.2 while installing stop responding.PLz help....

I have a very similar box. What are the error messages?

There are no error messages it just hangs and i have to restart it.....

That, my friend, is a 64 bit box like mine. Are you loading a 32 bit OS?
I would expect to see you loading Fedora-X86_64

Linux is not windows. Freezeups don't just happen - they are caused. Try
the command
less /var/log/messages and in the paged display type /error. look for sommething before a reboot and post it if you find it.

AS u have Said i have installed 32 bit fedor10 on 64 bit processor is that a problem is there any way to fix it without installing Fedora-X86_64 plz help..... these are error messages i have found after i typed /var/log/messages

Yes, that's the problem. The only thing you can do is to do a good install of the 64 bit OS, which you should have gone with during the first installation.

Install the right software, and your problems will go away.
