This is my first post and I hope you can help me with my problem.
About 8 years ago I successfully built 2 different computers and they have been running fine but as you know, Windows XP is not supported my many places.
With that in mind, I just finished building a new computer with the idea of installing Win 10.
The motherboard is a newly bought *ASUS Z170 PRO GAMING.*
The CPU is an Intel Core i5, 7th generation with a Noctua NH-L9x65 fan to keep it cool.
The hard drive is a SEAGATE BarraCuda 2 TB, SATA 6 unit.
**I installed 2 Ballistix Sport LT 8 GB ROM cards for a total of 16 GB of DDR 4 memory.
Also installed in a ENERMAX OSTROG case is a Antec 25, 650 watt power supply, 2 ASUS, 24X DVD players, and 3, 120mm Antec cooling fans.
The monitor is a small ASUS unit with a 19.5 inch screen. *It only has a VGA connection but I figured the Motherboard has a connection for that so what could be simpler?
**I took my time and referred to *several sets of instructions and the web for guidance and everything went together well.
Now, to my problem.
Using the guidance found on My Super PC on the web, I left the hard drive power disconnected for my first BOOT up. *(The author had not even installed his hard drive in the case when he did his first boot up.)
I connected the monitor and power cord plus an old (but good) keyboard using the PS2, 6 pin connector, plugged into the motherboards connection for that plug.
With everything ready to go I first turned on the power switch.
The Motherboard leds lit, 5 by the name, one in the lower right hand corner and a little Super whatever logo. *So far, so good.
I then poked the large "Start" key on the case. *All of the fans including the CPU cooler started running. *The DVD drives green lights lit and went out and the POWER led on the case lit.
THE PROBLEM is, the motherboard didn't make a single sound and the monitor screen stayed black. *Cycling the monitor off and on gave the ASUS logo and then said, No Connection and went black. *No sound from the motherboard.
Thinking I didn't have the Motherboards attention, I shut off the power, then after waiting 30 seconds I turned it back on. *The MB's LED's all lit.
Poking the Start button and holding the DELETE button on the keyboard the fans all started. *Still no BEEP or any sound at all from the motherboard. *The monitor stayed black.
I switched monitor to a well proven one with a VGA connector and went thru the drill again.
Again, no sound from the motherboard. *No image on the monitor.
*
*Thinking the Motherboard VGA connector might be bad I then disconnected all of the power and installed a Gigabite (can we say that here?) Radeon R7, 250 video card.
Connecting the monitor to that cards VGA connection and hooking up the power cord *and going thru the Start drill, no sound from the motherboard and a black monitor screen. ( The video card fan was running indicating to me that it was getting power.)
As a last hope, I disconnected the keyboard and installed the USB receiver for a new (and tested) wireless keyboard.
Again, no sound from the motherboard, a black screen on the monitor, LED's all glowing and winking slowly on the MB and all fans running fine.
Did I mention I also connected the power to the hard drive and went thru the cycle again.
The HDD indicator on the case occasionally flickered indicating the drive is running but still, no sound from the motherboard and no image on the monitor.
*That is when I decided to ask for your help.
The only thing I can think of is doing what MySupercomputer suggested and wiping the COMOS by removing the battery and then, assuming the monitor screen will show ANYTHING, reinstall the needed driver/data.
Please help.
At the moment, the only thing I can think of is the Motherboard is totally defective. 😞
