No post on reboot

[R-Type]

I have a DFI sli dr expert with the most recent bios and an optron 165 at 2.75ghz prime stable all day long. The thing is, maybe once ever 3 times I restart the screen will not initialize and my video card fan will run full speed. When i shut it off with the power button, it will then not turn on or even beep when I puch the power button until I unplug it and clear the cmos and press the power button to empty caps. Does anyone have any idea what might cause this? Startup VID perhaps?

Thanks

try doing a 24 hour cmos clear,

then you can try a reflashing your bios, that should help. And remeber dont use anyhting from cmos reloaded after you reflahs your bios or do a cmos clear.

Well the short cmos clear will let me boot it back up and set my bios up again and it will work fine. You're saying that flashing it again with the same bios i'm using now will clear up the issue?

Try changing the molexs that power everything into a configuration that balances the load. I personally consider VPU's= 2.5 drives for the calculations.
