A problem has been detected and windows has been shut down to prevent damage to your computer

PFN_LIST_CORRUPT

if this is the first time you've seen this error screen,restart your computer. if this screen appears again,follow these steps:

Check to make sure any new hardware or software is properly installed, if this is a new installation, ask your hardware and software
manufacturer for any windows update you might need.

if problems continue,disable or remove any newly installed hardware or software.disable BIOS memory options such as caching or shadowing.
if you need to use safemode to remove or disable components, restart your computer, press f8 to select advance startup options, and then
select safe mode

TEchnical information:

***STOP: 0x0000004E (0x00000099,0x00000000,0x00000000,0x00000000)

hello kimsland tnx for the info about the memtest86+ is used it and it help me.
i already solved the problem this morning.

this morning when i got home from work i check the memtest86+ i run for overnight i found millions of error, i check the RAM hardware one by one, i test the 512 and found error, and 258 has no error found so i only install the 258 and run xp installer and its ok now.the faulty 512RAM causing me the problem.
I buy a 1G for replacement of 512 but when i check it in the MY COMPUTER properties it only found 1092 memory of RAM is it ok. why is it didn't come up with 1g + 256 or something like that.how do i check or look inorder to know the two RAM or the 258 installed is running.
Thanks a lot..

If you remove the 256 meg does it change.

But here's a better answer, remove the 256 Meg card, useless anyway. If you want more, buy another 1 Gig (exactly the same as the one you bought)

Anyway, Good News. fault fixed and more ram installed, you must be happy with that.
