EMachine W3507, will not boot after adding 2GB of memory. (2x 1GB; one in each slot). It will boot with one stick, but only if the original 512MG is in slot 1. The 512MB is not recognized.

SOURCE: Upgrade problems

Your system comes stock with one stick of DDR2 (512 MB), which means that it is _ not_ dual channel DDR2 memory as dual channel DDR2 must be installed in matched pairs. Try to exchange the new memory for 2G of some single channel DDR2.

SOURCE: does my w3507 have an agp port

I found the specs below on their website. Sorry only a PCI Enhanced port, NO AGP. Hope this helps. Best Regards, -md CPU : Intel® Celeron® D Processor 352

FYI - PCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe (or PCI-E, as it is commonly called), is a computer expansion card standard designed to replace the older PCI, PCI-X, and AGP standards. Introduced by Intel in 2004, PCIe is the latest standard for expansion cards that is available on mainstream

SOURCE: added 2 1GB memory to

There are two variants of the T5048 One uses DDR PC3200 ram the other uses DDR2 PC5300
Should be able to look at the old ram and it should say on it what it is. If it doesn't, take out the new, put in the old ram and go here http://www.crucial.com/store/drammemory.aspx Run the "Scan My Computer"
Some computers will have a setting in BIOS to disable on board video although eMachine are very low end and probably don't offer that. Shouldn't need to just install your video card and plug your monitor into it. It should work just fine without disabling on board.

Comment if you need more help

SOURCE: emachine w3507 powers on but will not boot up

Ram modules might be dirty or dirt in ram sockets

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

http://www.kitchentablecomputers.com/static.php - rules

Only work inside the computer case when the power has been switched off and disconnected. Never open the power source.

Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards

Remove the memory modules from their slots.

Take the opportunity to clean the slots on the motherboards and the memory module connectors.

Use compressed air to blow dust away and clean contacts with a soft cloth.

Do not use a metallic vacuum cleaner if it touches any component it may create a short and cause damage to the motherboard or other components.

hope this helps
