Hey folks.

Win7 has installed. Just installing MB software so i can get some temps of it.

Nothing else is plugged in. MB seams secure though if i have another shutdown ill dissmantle and start again.
 
Tried that. Started windows, loaded up the desktop then within about 2 secs the screen went blank. computer was still on till i forced a shutdown :S
 
reseated, idles at 34 now.
started windows again, gets to the desktop and the screen goes blank again. it doesnt shutdown exactly, goes the screen goes. all fans still going etc.
 
just tried with the gpu agian. windows starts fine, lasts about a min before the screen freezes i can still see the desktop but cant move the mouse/keyboard.

im really confused.
 
Yep, cleared CMOS, and set memory timings myself.

Havnt done memtest yet, but i think its a problem with the mobo. I'm uploading a video atm so you can see what happens.
 
Ok, ran a memtest, no errors. Changed the PSU same problem.

There is a plus side though, just through general annoyance i reinstalled windows and so far it is stable. Only installed the MB drivers so far and im currently running a quick Prime95 test, so far highs of 74oC and been running for 10mins.

It might be sorted, though i'll wait a little longer before i celebrate too much.
 
:S
Go so first thing i did was to check windows update, detected 26 updates installed restarted, and the f*$@ing screen goes blank. Boot to safe mode, uninstall the updates that i just did and it seems to be fine again now.

FUUUUUUUU
 
Im loosing faith.

Updates were critical, i go back to do one update at a time. Install the first one, and the screen goes blank. Ok i think thats the dodgy one, tired to delete it in safe mode and it wouldnt let me. Went to system restore, reverted back to the one before the install and still the screen goes blank.

I have no idea what direction to go in now.
 
Tested connections
Memtest
Different PSU
Different Moniter
Different SATA/HDMI cables
Different SATA slots
Conventional HDD
Different amounts of ram
Different outputs on the onboard vga
Different outputs on the dedicated gpu
Update SSD and mobo firmware

Think thats about it. Just doing one more install of windows using SATA 3GBps not 6 (takes quite a bit longer actually). Shall report back with findings....
 
Ok, out of box. Been stable for 15mins now, though i havnt installed any drivers or done anything with it that usually messes things up.

What would you suggest i install/do in first? currently just on onboard gpu got both sticks of ram in.
 
No I'm afraid not.

Had it running for 20mins. Decided to try restarting it a few times and it all went well. Did 4 restarts (so quick, loving the ssd if only it all worked), all still fine. Decided I would go for Intels site for onboard drivers this time, instead of Gigabytes. Download install, restart, crash, died*, burnt in hell*.
Booted to safe mode, unistalled onboard vga drivers, restart and all is fine again.

So it seams like the gpu drivers might be my problem for some reason. Plugged in dedicated gpu, managed to get CCC installed, restarted and this is then what happens:
Just seems like the thing is allergic to drivers.
 
Ok, tried those ideas quickly and still nothing.

Im using the H67 because there are no P67 M-ITX, and i need M-ITX for the case. i got the 2500k on special offer through OCUK as it was cheaper than the non-k version.
MB is brand new.
 
I dont think its the PSU, i've had a 750W CoolerMaster from my main rig on it and it doesnt make any difference.

I'll try the CPU, then thats it.
