this one is pecular because it hesitates by about 10 seconds before it beeps without the ram installed and when the ram is installed it hesitates before the cpu vcore drops to .8v like it should but it doesn't want to post. i'm not sure what to check. all rails are present as far as i know

Even better to use an USB OSX pendrive with Link LED.
If flashes, then has 100% activity.
