Wake from sleep loop on a H55/Core I3 system

Hi,

I've been to MSI user boards, talked to their tech support, read the G.Skill boards, and nothing yet. Here's hoping for some ideas.

I have a H55M-E33 MSI board, Core I3 530/540 (building 3 of these), 4GB G.Skill F3-12800CL9D-4GBRL (DDR3 1066), HTPC Win 7 setup. Latest Intel chipset/graphics drivers. As a rule I only install drivers from chipset manufacturers.

Set up S3 sleep in BIOS with wake on USB, keyboard, mouse, PCI. Computer sleeps fine but every day, when I wake up usually, it'll be in a wake up loop. Power up, no POST, then power off, power up, no POST, etc.

Now if I use my Media center receive to power it up it works great. This seems to be timer related (show needs to record, or MCE optimization/update, etc., I have yet to be able to reproduce this manually consistently).

Is this type of problem more of a chipset issue, BIOS issue, or memory related issue?
I previously had a Gigabyte EP45 series motherboard/Core 2 cpu/DDR2 memory working fine with the same peripheral components. No wake issue. So it's gotta be one of those 3 issues, no?

I'm looking for any idea, no matter how crazy. MSI is giving me the "we see no problem in our testing" response. Working in the computer industry, as a developer, I can understand where that comes from but being on the customer side of it makes you crazy.

Welcome to the forum LurkingMenace Yes that does indeed sound strange, im not the biggest expert on hardware myself but I would like to ask you a few questions that I think may assist other members in determining your issue.
1) goto click on your start button and type "system information" into the search without qoutations press enter then after the window opens click on the plus beside "hardware resources" highlight conflict/sharing and goto the edit tab then select all then copy and past the information back in your next post.

I've been Google-ing and finally found something that seemed to worked, at least for 1 day. Disabling EIST and C1E has prevented the sleep loop. I assume it's voltage related. The MSI board has an auto-overclock ability that when enabled causes a few reboots while, I assume, it tries multiple clock speeds until the CPU responds. I'll bet there's some kind of bug related to that even though I do not have that enabled.

Regardless thanks for the quick reply.
