ML370 G2 processor Fail light Issue

I came in to find this server in question with a failed processor. It would boot and run on one, then reboot sometimes. This is a antivirus server running Win 2003.
I decided to install 2 new processors (same speed and matching) and the 2 VRM mods that came with them. The system seemed to boot and run for a little, then would reboot. Now I have a yellow fail light on the board by each processor and it won't start. I have reseated everything and checked all connections. I have full dual power and have network and MB lights. Am I missing something or has the board just failed?  

Thanks for the help.

Since the system is unreliable, why not eliminate windows and application software as the culprit.  Download an ubuntu live CD, pop up a game or something, let it run some read-only disk tests, etc .. .and see if it crashes.  If so, you KNOW it is hardware.

Note, if you have a HP support contract, then just call HP and let them verify everything.

Both processors have a yellow fail light on the board next to them. I even put in the one old processor, unplugged it, powered it back on and I get the same thing. No post, and a red light on the power button.

No matter what, you can always get replacement parts that arrive dead.  I suggest you download the online manual and go through troubleshooting to confirm the problem is specific to processors, and not motherboard.  I also wouldn't risk taking a perfectly good system and plugging in the new processors, you never know, the processors may be blowing the motherboard.

But bottom line, unless you have a motherboard diagnostic card & the right software used by professionals to diagnose/fix motherboard problems, then all you can do is run the manufacturer's trouble shooting guide.

Pretty old box, cheaper to buy another one on eBay than replace parts.

OK, after making a few changes, the sever fired up fine with no errors. I logged into windows and ran the management software. Everything looked good, motherboard, processors, memory. Great!
I did a few updates and started running programs and it was fine. The management software showed 2 processors, but I only see one running in the task mgr. The server was up for 45 minutes and then suddenly went into a mild shut off, still running, but no OS and a red light on the front notifying me of an internal issue. Now I have a yellow light only on processor one. Processor  two is dark.
Anyone have an idea in this scenario?

Hello, the final fix was to swap out the motherboard. I used the new processors and VRMs and 4. It has worked beautifully ever since. I also added 2 more gig of ram to 4gig and its fine.
Total spent about $200. Well worth it to keep this baby going.

Thanks for all the help
