Computer Just reboots no post.

About 3 week ago I was watching a bluray when the computer went to a memory dump and I allowed it to finish. Went to turn the PC back on and it would start for 3 seconds and reboot. This would keep up as long as you would allow it.

So I stopped it, pulled everything and tried again. The thing kept doing the same bit. It doesn't make it to post before it reboots. So thinking its a bad motherboard i called and RMA'ed the thing.

Its comes in and I reboot and long behold its the same thing. WAY longer boot before reboot put no post. It has no memory/drives/video connected to it, and yet it does not boot. Thinking it was a PSU problem now I buy a tester and the thing passes. I then grab my roommates working power supply (just the 20 pin and 8 pin) and see if it would start. No dice.

So now im left a little clueless. Is it the poor I7 (2600k) or did I manage to get yet another bad board?

Can I boot the board without the processor?

GA-Z68MX-UD2H-B3
I7 2600K

If not doesn't anyone have any ideas on a company/person that could help me test the I7 for little cost in the McKinney, Tx area?

Usually memory dumps are caused by one of three main things:

- CPU is unstable (OC isn't stable) and or heat issue is causing it to crash. Alternatively can be a sign of a bad CPU.
- Memory is OC'ed too high, not getting enough voltage, and or is bad. Try one stick at a time and different slots just in case.
- Drivers are bad (can explain a already booted crash/memory dump, not the restart bug though).
- Finally, Video Card is bad. Either not enough power is getting to it, it's OC'ed way too high, voltage too high/too low. Also could be a heat issue.

Make sure in all cases you have proper air flow to rule out heat. I would say monitor the heat in the BIOS but if you can't see the POST then it signals a video card related issue to me. I've never tried POST w/o a CPU installed, don't know if it's possible to be honest or what it would show, but if it was possible it would probably show something on screen allowing you to either break down a bad CPU/Video Card. Both of which can affect POST as they are the first things checked during the POST process. To me it boils down to those two. If you can boot without the video card then I'd say it's the CPU.

Ok update.

Gigbyte after speaking with them felt it was the processor. I said fine and called intel which $25 haste later got it to my house. Plug it in tonight and still the same thing. Did I really receive a board with the exact same problem as the last board?! I know you can get a bad board but the exact same problem?! Of course gigbyte is closed for the weekend. Anyone have any clue?

All drives, all ram, and the video card is not plugged in.

Is it possible to post without RAM? I don't think I've ever tried it. Did you try one stick at a time?

yeah, no post. tried all 4 sticks (one at a time). Yes they where the same 4 sticks that was in the system when it went dead. But whats the chances all 4 sticks went dead at the same time?

Tried all 4 sticks and no go. Drunk as heck friend decides to play tech guy, and it works for 3/4 memory. Old CPU, and motherboard are dead. WTF happened...

Not gonna question it and just go with it.

So note to self, if the mobo goes it takes everything with it. Also let drunk people play with the computer when your not looking.

I suspect a bad psu started all this.

are you overclocking? what kind of case and how many fans? using an aftermarket heatsink or standard intel heatsink on your CPU??

agreed its quite possible a bad power supply took out his system, one of the reasons why its always a good idea not to skimp on a quality PSU

but hasnt listed his PSU or if he overclocks
