Windows 7: Win7 64-bit blank screen after sleep/hibernate

Win7 64-bit blank screen after sleep/hibernate

Hi, apologies if this has already been discussed here.

I did a clean install of Windows 7 64-bit over the weekend. It looked great, installed a few games (WaW has issues but I think it's the driver Windows chose to dl for my ATI Radeon HD 2600). On Sunday the machine went into power save/sleep or hibernate mode (not sure which, as I usually disable this option). When I sat at the machine and clicked my mouse to "wake up" the system it kicked into life. All, that is, except my monitor.

The amber standby light changed to green (to indicate that it was receiving something) but the screen was completly black. Switching the standby button off and on revealled my desktop for a split second before returning to black again. I rebooted. My Dell splash screen and the loading windows splash screen appeared but as soon as it moved to the login screen it went black again. Same thing - switching monitor standby button off and on displayed my desktop/login page as is should but only for a split second.

So far I've
  • removed and reseated my graphics card. no joy!
  • switched to my onboard graphics. no joy!
  • removed two sticks of RAM. no joy.
I'm taking a monitor from work tonight and I'll try that when I get home to rule out any coincidental monitor issue.

I don't think it's the graphics card or monitor because I can get to see the desktop for a split second by flicking the standby button, proving that there's something getting to the screen.

I've read about various hibernate bugs with Windows 7 beta and release candidate but surely these would have been resolved?

Anyone experience this? Any ideas?

Thanks in advance for your help.

I powered down my machine all day while at work and when I came home tonight I crossed my fingers and rebooted. I was fine! Whatever happened has been resolved. I disabled the sleep mode because it must have been related to that!
