System Lockup

[Jeffrey D. Yuille]

Hello,

     I am currently have Fedora Core 4 installed on a Dell Dimension XPS 
T600R desktop and I am experiencing intermitent lockups whenever I have 
multiple programs open at the same time (for example, Mplayer, Firefox 
and FreeCell Solitaire).  I also have Fedora Core 4 installed on a Dell 
Inspiron 4000 Laptop and I am having no problems at all with lockups. On 
the desktop, I have 384 MG of ram installed and I never experienced this 
problem with previous versions of Fedora (Fedora 2 and 3).  Is this a 
bug and is there a fix for this?  Should I report this to Bugzilla?  Any 
help would be greatly appreciated.
