Kernel-power Error 41 (63)

[Keepmealive]

Im actually running into Kernel-power 41. Rebooting randomly without BSOD.
My system is:

Mobo: ECS h61h2-m2 Bios V 2.0
Intel® Core™ i5-2310 Processor
Not sure on my RAM, 1x DDR 4GB
PSU Corsair CX 430 (brand new)
Graphics Card (brand new, tested for disabling onboard graphics) EVGA GT210

The following steps were based on advice from other threads on toms, or other forums. For each step I awaited for at least 1 random reboot to move forward and keep testing.

First of all, installed Win7 x64 in a clean slate. Installed all needed and updated drivers.
Then I ran Open Hardware Monitor and CPU-Z, no temperature, voltage or clock looking weird.
next, installed new PSU, then graphics card. Disabled Intelspeedstep on bios, aswell as any overclock setting, and onboard audio card.
next, deleted RACTASK and removed ALL sleep settings and energy saving options.
Ran memtest86, all good with my RAM. Checked mobo for defective caps, none bent or busted.

The reboots come fast and without BSOD, they got better, but still happening with cold boot, after 1-2 hours rolling I can work all day (8am-5pm) without a problem, but the first hour i still get 1-4 random reboots. I got better with heat and after installing the graphics card. I'm guessing some circuit or mobo/processor pin got busted/bent somehow and it is dilating with heat and working fine after that. Thoughts ? What did I forget to test ?

Clarify me this, the issue was happening before with another PSU? in that case since the problem persists with a new one (though the Corsair CX series' reliability isn't really that good, for your system it shouldn't be already presenting issues) then the problem must be the mobo, some capacitor very likely even though there's no physical sign one or more capacitors might be failing.

A long shot could be a BIOS instability so just to eliminate even the most remote possibilities see if updating your BIOS fixes the issue, but most likely is a hardware failure in your mobo.

My BIOS is in the latest version and i'm hell sure all BIOS settings are set to try to avoid this issue, and yes, I had the same problem with the older PSU, I upgraded from a ordinary 300W PSU to the 430CX. Since this system wasn't with me to begin with, it is my work computer, i don't know who build it ou repaired, thus my fear of damage by tightening too much the heatsink and so. But this system ran for about 6 month with no isssue with the factory PSU, then started those random reboots.

Edit: I'll re-check my caps Monday as soon as I get to work, but I checked once and none were bursting out/oozing or bent when I did.

Capacitors visually rechecked, 2 very slightly bent, all the others are good. I'll send to a friend who can test my mobo and my stuff on another mobo and get the veredict, I guess.

Edit: I´ve decided to see how far this mobo can go, its 72 hours online without a crash, only crash in cold boot, only once. I'll keep this topic updated.
