I'm having the same problem as caddie.
However I don't even have a signal on my monitor.
It says "no signal" at all time.
The system have been working I been trying to install Vista home premium twice but it stops when finishing decompression of files. The CPU fan goes up in speed during decompression but slows down before the screen goes black.
Corsair CM2X1024-6400 in a twin package. I'm pretty sure that these can be used.
Eventhough Asus writes this: CM2X1024-6400C4
But I don't know what this C4 means?
CPU: Intel core 2 duo E6750 (Standard fan)
Hard drive: 2x Samsung 250 GB (SATA) (Set to raid0)
DVD drive: Lite-on (SATA)
TV-card: Hauppauge HVR-1300 MCE
Memory: Corsair CM2X1024-6400 (XMS2 2x1 GB)
Could it be something with the voltage for the memory?
Or could it be something with the CPU temperature settings?
I wasn't working on the computer for over a day when it suddenly started normally the second time I tried to install Vista.
Only one memory stick won't help.
I'm not getting any beeps at all.
I had two issues with this board.. One was that PC was crashing, BlueScreen, ( and on TV would see no signal since PC was not restarting after the BlueScreen crash). When I would power cycle the system I would get a BIOS error saying that overclocking failed but I run everything at auto.
So in my case the issue was underpowered OCZ Plat 2 memory. I called ASUS and OCZ and was recommended to increase the Voltage to 2. That solved the Bluescreen crash for me.
Second issue was Vista freezing at random intervals. Mostly when PC was idle. Never (so far) when I used it. Just today ASUS released a BIOS Update 0405 I think which I upgraded too. So far so good and Vista seems stable. Customer support tech informed me that 0405 does address multiple power management issues and OS stability.
So I hope this was it for me.
