It is very important to know how many beeps you are getting when testing the motherboard with the video card but without memory. If you are not getting 3 beeps, I am pretty sure you have a defective unit.
These are some recommendations for this issue:
- Test the system out of the chassis, minimal configuration please. (Motherboard, processor, power supply, 1 memory stick and video card)
- Remove the CMOS battery and leave the system without it for about an hour. Then put it back on and restart the system.
-If you still having the same issue and if the motherboard is still under warranty please get in touch with our Warranty Department so they can help you to replace the unit: http://www.intel.com/p/en_US/support/contactsupport
Thanks a lot for your fast reply!
The error beep without memory seems to be the correct one: 3 beeps. I forgot to mention this in the frist place, sorry. This is what keeps me hope that the motherboard is still alive...
Unfortunately the board is not under warranty anymore. Warranty expired recently (although this specific board is not that old, since I got a new one at the end of the warranty because I had a different problem with my original board).
I'll give your hints one more try. Taking out the battery only 10 minutes wasn't enough (but I don't have more time right now).
Please try to leave the system without the CMOS battery for at least 1 hour. If this does not fix the issue and since the board is not under warranty anymore, the next option will be to test or replace the video card your are using.
Leaving the system also for several hours without CMOS battery did not show any effect.
Finally I managed to try another video card - with partial success!
The computer boots again. Strangly video works only using the VGA of the monitor. This means: no video signal if I connect DVI to DVI (I tried two different monitors and several cables). But if I use a DVI to VGA adapter, it works also using the DVI out of the video card. But maybe also the second video card is broken (it is old). I'll buy a new one and hope that this will resolve my problems.
Also a second issue still makes me wonder. I'd expect an error beep if there is no video card attached to the board, but there is no beep.
