I recently upgraded my computer with new motherboard, memory, cpu graphic card and hard drive. After assembling, it started up and worked great. Later, I got the really bright idea of trying to add some of the old DDR memory from the old computer into the DDR2 memory slots. I was able to insert the memory without forcing it so I thought, wow, maybe it will be backward compatible to my old memory! So, I started it up and got nothing. No post up. Took the DDR2 memory in to be tested and they said it was dead. Ordered a new module and still get nothing. I reset the CMOS, also took the battery out and reinserted and still nothing. Then we went on a planned vacation. (I haven't told my wife about any of this yet.)
Back from vacation now, I tried to duplicate what I did by inserting a DDR module into the DDR2 slot and it's impossible. The notches definitely don't line up. So, I must have forced it in.
So my purpose in this note is to try and get some idea where the problem may now be? The computer fans start but there is no boot up at all.
