If the module is bent and not cracked, then try to straighten it. Before you try that, is that module identical to the other modules in your system?
i have one more 1 gb module which is same and that one works on my motherboard.
the problem is then i installed all the memeory 2x2gb and 2x 1gb. windows 7 crashed on startup after few seconds.
and i Re installed windows 7 and it worked i installed some programs and then i shut down the pc and next morning i got same problem. it crashed on start up. then i testen all module one by one and found out that this one was causing trouble.
