Hello everyone, This is my first post. I have read thru the sticky emachines topic above. THanks for the heads up. I was never aware. Look at my specs that I have listed and you will see I own an Emachines W2646. I've had this since the day my ex-wife bought it over 4 yrs ago. The only thing that I have changed was the vid card, gvae ti 2gigs of ram, and a 250g HDD over a span of 3yrs. Now that I am starting to look at new PSU's due to the thread above, and the fact that the current psu is very old, I am looking at upgrading the spu as well. I have seen multiple threads stating that you can or can't upgrade the cpu. So, I would like to know, is there a CPU that I can upgrade to from the current stock cpu in the W2646? I just want to upgrade to something a little more stronger. Not crazy high, just a smaller boost. IF this is not possible, then please let me know what else I can do to further extend the life of my ancient W2646 as it has held on with me thru so many bad momments of my unexperienced comp repair skills.
