Asrock X79 Extreme4 - i7-3820 no POST

post #1 of 6
Thread Starter 
Hi

I'm having some problems with my computer for a couple of days now. Last week I overclocked the processor and after seeing high temperatures (around 80ÂșC in the graphics card, more than usual), I just undid the overclocking and left everything as default. I am not saying this is the cause, just giving information in case it's important.

The info about my pc is in my signature.

Two days ago, I was browsing with a game opened when the computer just turned off.

When I try to turn it on again, it has electricity (fans and leds are working) but the screen shows nothing. The reset button doesn't work, and I have to turn it off pressing the power button for 5+ seconds.

I have tried the screen in another computer, and it works fine.

I have resetted the bios using the clear CMOS button that the motherboard has. I have also disconnected the battery to reset it.

I have unpplugged and plugged again the 4 sticks of RAM, the graphic card and all the PSU connections.

I tried using 1 stick of RAM at a time, to see if one of them was faulty, but the result was the same.

I have tried another graphic card (an old 9800GTX+ I had) and nothing.

I have tried with another PSU (of 550W instead of 700W, but I think it should be enough to at least POST). Just connecting the 24 pin connector, the 4 pin connector and the 2 graphic card connectors.

The motherboard has a LED display to show codes (Dr. Debug) and it get stacked in the code "01". According to the Asrock webpage is a memory or CPU problem. According to the motherboard manual is "Power on. Reset type detection (soft/hard)". I don't know what it means.

I don't think the problem is in the hard drive, since I don't even get to the point where the OS is loaded.

After doing all of this, I think the problem has to be CPU or MoBo related, but I don't know how to know which one it is. The socket is 2011 so my old computer is not compatible with it, and I don't have any other CPU to change and see if it's working.

Any help or ideas ^^?

have you tried removing all fans and other connection you don't need just to see if you can get bios up
sounds like you had a electrical short on something for it to just switch off like that

Well, thanks for the help, but I just took it to the place I bought it to get it repaired.

It seems like the CPU was dead (I don't know why) so it has to be changed.
