Windows 7: Bringing windows out of sleep crashing issues

Ive had windows 7 ult installed now for just over a week, and the on single issue ive been having with is, I put it to sleep every night, when i try and bring out of sleep everyday, it comes up fine to windows logon screen, but then crashes to blue screen within a couple seconds. This happens everyday.

Other than that I have no other stability issues.

As far as I know all my drivers are up to date and i have no idea what else to do...

Not t o thread jack, I've had problems with "waking" my computer, but I think its because I have a slightly underpowered PSU: AMD Phemon x3 2100mhz, GeForce 9600 GT OC, 1 SATA HDD, 2 IDE HDDs, 1 SATA DVD-RW, 1 USB HDD.

When I did try wake my computer, I would hear the GPU fan & CPU fan kick on, and after afew seconds I would hear the HDDs switching on. As soon as one of them clicks on...power goes out (so to speak). I have not narrowed it down to which HDD it is, because for now I do not let Windows 7 go into sleep/hibernate mode.

hmm...sounds a bit different than my problem but I have an update...The last 3 times ive brought it out of sleep ive actually been able to log into windows b4 it blue screens, unlike the previous times. And each time it lasts progressively longer in windows b4 the crash.The first time ( i was able to get it into windows) it lasted maybe 5 secs b4 crash. Second time maybe 30 secs. Third, which was maybe 15 mins ago it mustve lasted at least 5 mins b4 it crashed to blue screen. weird...
