Re-OC'd a month ago, moved houses this weekend, and now my rig won't POST.

I hate to bring you guys another POST thread, but I just haven't found anything on Google or here at Tom's that helps me out. I'm afraid that this moving is just coincidental, but it may be a problem with my OC a month ago...

My rig:
MSI 890GXM-G65
AMD Phenom II x4 960T Zosma (O.C. 4.0GHz, base clock 250mhz x16)
OCZ Agility 3 AGT3-25SAT3-60G
G.Skill Ripjaws X Series 2x4GB DDR3 1333
ZALMAN CNPS9700 110mm cooler
COOLER MASTER Silent Pro M600
XFX Radeon HD 6850

I previously had an OC where I was clocked up to 4.0GHz leaving the base clock at 200mhz x20, and had my voltage cranked up higher than this previous one. Worked fine, but a year later I wanted to re-clock it more efficiently and to boost my NB, so I reclocked it tweaking the base clock.

About two weeks after doing so, I began to have issues with Windows freezing at the welcome screen and on the shutdown screen, so assuming it was instability, I bumped the voltage only a bit, trying the CPU, NB, and RAM voltages.

Last week, I left it unplugged and packed in the original case box with foam to move it to my new house, and it's been cold for a few days. When I tried plugging it back in yesterday, it would no longer POST. I've tried everything except for reseating the CPU and motherboard, which I will try tonight. I tried different RAM also and it still wouldn't post.

EDIT: Also, I have tried bringing it to work where it's much warmer and it still won't POST.

In sum, here's what I'm asking: does anything obvious stick out to you who are more experienced than I? I don't have an extra motherboard or CPU to try out, so is there any way that I can figure out specifically which piece is broken so I can RMA it?

Thanks in advance for your help...

Unfortunately I'm not aware of a method with regular means, without swapping parts (CPU or motherboard).
What you can try though, is reseating the CPU and reinstalling the CPU cooler (taking into account that you've moved the case with the CPU cooler installed).

CPU and case fans are indeed spinning. I have also now tried a different PSU and nothing has changed. As for the case speaker, I believe the cylindrical piece that's integrated into the motherboard is the case speaker and I can't locate a place to plug in another one.

Yes, I tested that yesterday and it did not beep, but I couldn't remember if it used to beep or not (you tend to tune the normal things out over time... lol) Further research suggests that that cylinder is the case speaker.

I've also dug this up:

"also not sure but according to comments here MSI boards have a higher failure rate with AMD processors with high TDP(like 6 cores & heavily overclocked 4 cores)because of their poor VRM."

Does this make sense to you?


EDIT:


How can I reset the GPU RAM? Isn't that integrated into the card? I've tested my rig without the add-in GPU and it still exhibits the same problems.

Both are still under warranty. Do you have any suggestion how I can troubleshoot which part is faulty? I don't have access to an extra board or CPU to test each and I'd rather not RMA both pieces if only one is faulty.

Turns out, apparently my enormous fan caused my CPU to wiggle out of its plug? When I tried to gently pull off the heatsink last night, the processor came right out with it. I then cleaned off the CPU and the heatsink and reapplied them and it booted right up...

Again, thanks for your advice everybody. I really appreciate it :)
