Error loading operating system

Hello,

I am using Windows XP and have, several times, encountered a blue screen problem. Attached herewith are two of such blue screens that I have encountered.

The common thing that occurred after these two (and the other) blue screen problems is an
'Error loading operating system' message after I reboot my PC.

Please advise on the possible causes of this problem and how I may conclusively fix it.

Thank you.

according to above link this error is mostly caused by memory

below are links to download memtest86+ and imgburn, you will want to create a bootable cd with imgburn of the memtest86+ iso image.

insure that you read each page of the installation so that you do not install any unwanted extra softwares.
