Win 7 64 fails to run after loaded

About 3 months ago, I built a new PC arround a i7 960, Asus P6X58D_E, Gforce 470 GTX, 6 Gb Mushkin 1600 RAM, in dual boot with XP and Win7 64.- I could overclock it to 4,4Ghz stable, but as here is now summer, I am working with 4,3 Ghz with lower voltages, and stable.-
The only problem I had occasionally, and in a very few times, was that during the boot process, the display showed transitorily a strange and distorted color pattern, and afterwards within Windows 7, a warning box informed that the display driver had succesfully recovered from a failure.-
Since 2 weeks ago, I have a new problem:
Most of the times I try to boot in Win 7 64, after all the process, and when the desktop is ready, the display turns off black, sometimes it happens inmediately and sometimes within the first 5 minutes, so I must shut off power an reboot.- If the session survives that time, all works perfectly well.-
Sometimes I have to boot 2 or 3 times to get things work.-
As I guessed it could be a graphics system problem, I tried installing most of the NVidia 260 series drivers with the same results.-
I tried checking the events register, but the only errors related were those warning about having booted after an abnormal shut off.-
It seems not to be a hardware problem, as I can boot and run XP normally.-
Maybe somebody has an explanation for my problem
Thanks
Jorge

Does your rig do this without it being overclocked at all? In other words, running at stock in Win 7?

I dont think OC is the problem as I ran OK Win 7 64 for about 2 months with the actual setting, and Win XP loads an runs OK now.-
Also because when actually after some rebootings, I achive success loading and running Win 7, there are no further stability problems.-
Thanks

XP is a lot less sensitive to overclocking than are Vista/Win7 -- you can sometimes get XP to run on marginal OC'd hardware that Vista/Win7 will simply choke on.

Just because it previously worked previously while OC'd doesn't mean that some some component isn't now showing stress and is affecting system stability. If you haven't done any stability testing lately, I'd throw Orthos/Stress Prime 2004 or Memtest86 on it for a few hours. If there are hardware problems related to the overclock, it will likely show up pretty quickly under Orthos.

This doesn't answer my question.....
