Having a bit of a nightmare with my recent rebuild:
MSI GD65
i5 750
2*2GB Gskill Ripjaw PC12800 7-7-7-24
850W NorthQ Black Magic Modular PSU
Leadtek GTX 280
Basically when I load a game, or other 3d application (furmark), by system resets itself within a couple of seconds. I should point out that this didn't happen with my old mobo/ram/cpu combo (S775/E4300/DDR2)
My first thought was maybe PSU, but it should be capable (it's quad SLI rated, and got a pretty good write up on jonnyguru: http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=93) and for testing purposes, I unplugged my soundcard, unnecessary USB devices, DVD-RW, extra HDs etc.
I reset everything to default in BIOS, then I also disabled two CPU cores and underclocked the others to less than half speed (9x multi). I removed a stick of RAM and tried different sticks/slots. I also tried different cables (modular psu) and tried running the mobo just sat on the desk outside the case.
I also installed Windows 7 (on a different HD) and tried that to rule out any OS problems.
I'm pretty much certain that it's not down to a problem with temps because it happens so fast - it's not like I even get into play the game, it'll just crash in the menu.
So after many hours of faffing about, I thought hmm, maybe the crash is occurring when the card ramps up to 3d clocks. So using Rivatuner I set the gpu and RAM speeds as low as possible for performance 3d - and this seems to have done the trick, no more crashing.
Now the question is, why is this happening? I can think of two possibilities:
1) PSU can't handle the extra strain. It's got 4 25A 12v rails, maybe it just can't hack it and needs something with more juice on a single rail (does it share with anything else?)
2) GPU has somehow got borked during the migration, seems unlikely as it was working fine in old rig - I may test this sometime
As a workaround I'm currently experimenting with the following:
-Set 3D clocks as low as possible
-Load game
-Alt-tab back to windows
-Reset 3D clocks to default
-Alt-tab back into game
Seemed OK when I tried it but that was only for 30s or so, will have to see how it stands up to a proper gaming session.
