turns out it wasnt the ram but the ram slot on the board... my comp works now!!! phew dude.. =DD
[edit]
It turns out after a bit of consideration, i accidently placed my hand on my heatsink... guess what? it was LOOSE!! Im running a pentium rig.. if i read somewhere correctly, when the heatsink is removed from the pentium, it shuts off to prevent damage! so on booting windows it shut it self off to prevent damage.. wow.. couldnt believe i overlooked that!
