ASROCK Fatal1ty 990FX Professional PROBLEMS
HY FROM CROATIA I HAVE A PROBLEM WITH MBO
TURNED INTERNET UPSIDE DOWN BUT NO SOLUTION OR HELP.

SPECS
Case -Collermaster CM690 WHITE
CPU - AMD PHENOM II T1100
CPU Cooler - CNPS11X ZALMAN
Motherboard - Fatal1ty 990FX Professional
GPU - TRIED 3 OF THEM:ASUS 6850, SAPPHIRE 5850, SAPPHIRE 5450
Memory - CORSAIR LOW PROFILE 2x4GB
PSU - TRIED 2 OF THEM CORSAIR TX750 AND TX850
HDD - SSD CORSAIR 120gb

Everything worked fine for about 2 weeks but one day:
On boot, it seems as though the motherboard isn't powering on, although the case fans/leds and CPU and GPU fans all turn on. There is no video being displayed to the monitor through either VGA/DVI/HDMI, no beeps, and Dr Debug LED on the motherboard does not light up at any point and reset and power button on MBO stay off allso. I've made sure all connections were secure, CPU pins are OK, tested each RAM slot and only used 1 stick. I've also tried using a USB keyboard and PS2 keyboard, used all PCIE slots with different VGA cards . I've also tried removing the CMOS battery and clear CMOS wihh JUMPER and with BUTTON fow short and 8 hours long period of times multiplle times, did not seem to help.

PC has worked just 2 weeks, I cant belive that those HI grade new components can die so fast. Will se if someone knows anything about it because I've seen few IDENTICAL problems with Asrock MBO over the internet but no solution

TRIED ALL OF THIS WITH DISMANTLED EVERYHTHING, TAKE OUT CPU, ALL POSSIBLE COMBINATIONS OUTSIDE THE CASE on a table... NO GO
PLEASE HELP IF POSSIBLE (i think its the bios bug or something or bios chip died - did not overclock nothingat any point)

Do you or a friend have any other memory stick(s) you can test with?

It looks like your 8-pin EPS12v psu cable isn't delivering power to your motherboard.
It might be a psu problem, but you tried with two different power supplies.
Disconnect the power supply A.C. cord and carefully inspect the 8-pin socket on the motherboard for any signs of damage.
Inspect the rest of the motherboard for any signs of physical or electrical damage, including the bottom too.
Also check that the cpu heatsink is secure.
Can you borrow a third power supply for testing?
Disconnect all hardware that isn't required for booting into the bios.
Your immediate goal is to get your system to post.
If it posts, you can add components one at a time to help find out if one of them is the cause of your problems.

I measured all voltages on all connectors on both PSU-s with voltmeter and all voltages are OK (around 3,36; 5,03 and 12,03 Volts) so the PSU-s are 100% OK. Board has no visible electronic damage or whatsoever. I think I'm out of options here. Asrock support did not reply jet I emailed them 3 days ago over their web site form. Only thing I need to test is CPU will get my hands on another one ASAP. If someone knows direct Asrock support mail this could help also.

Can't say I've ever heard of it but check that the Clear CMOS button under the PS/2 keyboard port on the rear I/O panel isn't somehow held in or otherwise jammed or somehow depressed in the Clear position.

You've done everything I'd have done.

Not to sound repetitive, as it's being considered in another thread, but try replacing the CMOS battery with a new one.
