For the GPU :
Furemark. Use the stability test and Xtrem burning mode option. Look at it for 8-10 minut and try to see if you can catch any artifact of graphic bug.

http://www.techpowerup.com/atitool/Memory : Start multiple instence of this memtest with a value of 512 each. Make sure you DO NOT exeed complete system memory. If you have 1GB and windows use 512MB then start 1 with 512 for a total of 1GB, you follow me?
http://hcidesign.com/memtest/HDD : Depending of the brand of the HD, use the manufacturer test. If you are more techy the Hitachi drive test ( the bootable one ) is the best and it work with any drive, but you have to know how to make it bootable.
Complete system stress test : Download Everest Ultimate install it and start the stress test in the tools section if I remember.
