RedHat 9 System Lockup, Caps / Scroll Lock Flashing

Hi,

I'm new to linux, I'm dual booting RedHat 9 with Windows XP. When I'm in Linux my computer will sometimes freeze for no reason at all, and the Caps/Scroll lock lights on my keyboard flash.

This often happens when I'm just reading a webpage or doing something that I wouldn't think would cause the system to crash. All crashes I've ever seen before come from launching a program or actually doing something. This is happening for no apparent reason at all. Can anyone offer suggestions?

I'm running Gnome with kernel 2.4.20 on a 1.8 ghz P4 with 512 DDR Ram

I love linux when it works but I hate it when this happens!

did you disable plug n play in the bios?

Flashing caps and scroll lock LEDs indicate a kernel panic, a serious error which really shouldn't happen. Except some user-caused stuff at system boot, they are extremely rare and almost always point to some kind of serious hardware failure, such a defective RAM modules or the like. Windows is sometimes more tolerant of these things.
Try your memory modules with the program at http://www.memtest86.com/. It takes a long time to run the entire test series, so you might want to leave it on overnight or so. If you have the time, run the tests several times.
