I've built a newish pc which periodocally (1/3 roughly) has problems waking from sleep. I'm using the Lucid Lugix Virtu so it keeps the CPU processor HD3000 and the Discrete GPU active. When i move the mouse or click the keyboard during sleep, the fans spin up, and the GPU fan spins up loudly to 100% but the monitor doesn't wake and I have to do a hard reset which then brings me back to the EFI BIOS (U1C version) which takes ages. I have disabled hybrid sleep as this has caused problems in the past. When it happens, Windows doesn't seem to always detect the crash and pop up the advisor. Sometimes it just blue screens on wake. Has anybody else got a suggestion as to diagnosing this problem? My first stab would be to disable Virtu or take out the discrete card to see if this is the problem, but looking for advise really. I'm running the latest version of the drivers for both the graphics card and the Virtu software.
