    Hi guys new to the forums here was told that this was a helpful computer place :)

    So basically what is going on is this. I shut down my computer after working fine, the next day I turned it back on and got a black screen saying "Digital power saving mode" no bios or anything.

    I tested the screen on another computer, with the blue cable as the other computer did not have the white connector as mine does. Screen worked fine!

    At this point I just brought my computer into best buy and they did a few quick checks before handing it back. I watched him check the power supply with his tools, and pull my gcard and put one of theirs in and STILL black screen.... He told me that in his opinion I had a bad motherboard because it was not reading his card either, again no bios.

    Sooo seeing that I make a living working from my computer (cad designer) I couldn't afford to NOT have my computer running so I ordered another (the same) motherboard Asus P6t Deluxe V2.

    After reinstalling the motherboard I STILL HAVE A BLACK SCREEN saying "digital power saving mode" it's now been a week and a half since my computer has been running I NEED HELP!

    So basically it isn't the motherboard, power supply, monitor or memory (checked that too) that really only leaves me with my graphics card ( nvidea gtx 295) or the processor I7 920 sitting under a cooler master V8.

    Is that about right? How am I suppose to check my gcard when it's bigger than the computer than anyone I know!? And processor is there a way to check this? am I missing something?

    Thanks for all/ANY help!

    Have you tried clearing the cmos by either unplugging and removing the battery for five minutes or moving the jumper.

    Don't forget to reset the date if the cmos is reset.

    Try booting with just one stick of ram then another.

    You really need to get the bios beep codes going again so try the above as first steps.

    I'd try another monitor with digital input. Also try your monitor with a computer that has digital output.

    When the computer cannot post and does not give any sound warnings (assuming the power supply and mobo are ok), is caused by a problematic cpu , memory or gpu.

    Since you have checked your ram and at the store have checked it with another gpu, means is your cpu; the only way to test a cpu is to install it on another system.

    hope it helps,

    For clarification, you mean no BIOS only because you don't see the POST messages or also because you don't get the audible beep?
