If the system eventually powers up, you've found good memory — probably your only problem — and you're probably done. Put the stripped-down version back into the case and secure it. If it powers up again, skip to step 9.

If not, you need to remove it again and investigate the setup of your motherboard standoffs and make sure nothing is touching the motherboard where it should not be touched. After this is done and all is well with the basics inside the case, skip to step 9.

If it fails to power up with any memory configuration out of the case, we know it must be either the CPU, the memory, the video, the motherboard, or the power supply, or any combination thereof.

With this in mind, and our system still out of the case, we continue.
