Problems with Fedora 15

['Zeus]

I have installed it, everything went smoothly, but now, something is wrong, after log in to my user, it works perfect but after some time, every thing gets struck, nothing work, cursor disappears so that I have to switched it off.

its happening to my old PC. its a dell machine, Optiplex GX-270 with Pentium 4 CPU 2.66 GHz and 1 GB of RAM and ATI Radeon 9250 Graphics card.

There are known issues with Fedora 15 freezing up on you when running on either a VM or Dual OS Boot. So lets start there - are you running it on VM or Dual boot?
Did you do a clean/fresh install of the OS or an upgrade?

Please provide the system log files.

Edit - Just in case your not sure which log files to review: Are there any clues or outright errors logged in in ~/.xsession-*, /var/log/Xorg*.log, /var/log/messages or other system or daemon logs?

It's easy to rule out hardware problems:
I'd suggest starting by running a memtest and a disk diagnostic.
Linux uses memory much harder than say XP, so you can get by a memory error on XP that will cause Linux to fail. Memtest can be run from almost any live CD or from the grub boot menu if that's what you're using.
Or, you'll get all the diagnostics from any one of a number of troubleshooting distributions:

You must be registered for see links

Also, being a Dell, if you can still get into it, your utility partition contains diagnostics. I think it's an "F11" at the boot if you haven't over-written the Dell boot partition

I fixed it. ;D it was due to my graphics card. I'm using fedora for 2 hours continuously and its working smoothly.
