Oh, I'm sorry. ^^;;
To run a memory test, go
here and download MemTest for Windows. After that you'll need a clean, empty floppy disk, and the program will install onto the disk. It'll be unreadable by Windows afterwards, but don't worry.
Now boot from the disk. If your PC doesn't do it automatically while the disk is inserted, go into a Boot Options (usually F2 at startup) and select the floppy drive as the main boot device. Then just let the program run. [img]smile.gif[/img]
