HI
gpu would not have caused no post.
first check the cmos battery must be at least 3v if ok
try removeing one stick of memory and then the other if you have two.
the next thing to do is post some information and pictures of what you are working on and let us know what you have tried.

Hi

CMOS battery is about 2.7v so I guess that is ok. I have tried known working rams. So far Im not working on any section as I dont know where to start or what to look for.
