Hello everyone, I need help with starting my computer
I built a computer and its my first build.
The components are:
Asus p8z77-v lx motherboard
8gb Corsair Ram 2 x 4 GB DDR3
Intel core i5 3350p CPU
Sapphire Radeon HD 7850 2gb OC edition
Corsair 500w power supply
half a gb hdd western digi caviar blue

When I turn the Compter on it does not post to the monitor, I am running it through a HDMi, all fans and components are running and mainly all looks good, The problem is that the DRAM LED light is flashing red, When i Hold the MemOk button for 3 seconds it turns the computer off. I have checked that the RAM is fully clipped in over 10 times and have took it out of the slots and back in.

I need help on what to do and how to fix this problems as I have ran out of ideas and the asus helpline was dreadful and blamed my monitor.

Thanks for any upcoming help I will be very grateful

Hi,
The CPU requires the 0610 BIOS version. There's a barcode sticker on the motherboard.
The last 4 digits stand for the board's BIOS version.
Have you tried starting the board with only one RAM stick inserted?

What do you mean about the BIOS how do I do anything to do with BIOS without seeing anything on the monitor?
And also I have tried with one RAM stick and it is exactly the same

Thanks for helping

On the motherboard (right side) there's a narrow sticker (with a barcode).
The last 4 digits on that sticker stand for the board's original BIOS version.
If older than 0610 then there are some options, but firstly check it.

the last 4 digits on the barcode are 0610?

Then the CPU is supported and it should work.
Try taking the board outside the case and test again with a minimum configuration.
Install single RAM module in each slot and test.
If still the same, try reinstalling the CPU and check the CPU socket for bent pins.

what do i need to plug in outside of the case? As it is turning on for 1 second when i switched it on? I have plugged in 1 ram stick, the cpu, graphics card, power supply and the case power suppliers (power switch, reset sw etc.)

ok silly me, i plugged in the motherboard and turned it on. I have one stick in the blue ram slot closest to the cpu, when i turned on the computer the DRAM light flashed once and thats it? What does this mean?

It means that the RAMs checked OK.
Are the graphics card, keyboard, mouse, DVD drive installed?

Even if it flashes once red? what do you mean by installed, how can i install them without a monitor?
thanks for your replies

When it flashes once it means that the system checked the memory and it's OK. By installed I mean connected.
March 2, 2013 5:27:47 PM

oh yeah they are all installed

Does the graphics card require PCIe power cables? Are they connected?
March 2, 2013 5:57:35 PM

The PCIe cable is plugged in, 4 pin plug plugged in.
The graphics card runs fine and the fans are running.

How is the monitor connected (DVI to DVI, VGA to VGA)?
March 2, 2013 6:04:59 PM

HDMI?

I've seen cases where the monitor would not show any image until Windows loaded.
When starting the board, do the DVD and HDD drives show activity (DVD drive led flashing, HDD noise)? Are all CPU, GPU and case fans spinning?

Hi,

I have the exact same problem with nearly same configuration. Sometimes monitor goes on when i start the computer and sometimes i can't get video display. My mobo's driver version is 1502. What can I do about it?

Hi,
Using the HDMI? If yes, have you tried the DVI port and still the same?
May 6, 2013 4:47:44 AM

Hi thanks for your reply,

It's DVI. I'm using Win. 7. My graphic card is Zotac geforce gtx 660. I've updated it to latest driver. I have tried to connect the monitor to onboard DVI connector when i'm having this problem too but it didn't help. When I click to the power button, fans start to spin and it seems that everything works as expected but monitor doesn't show anything. Starting, shutting, starting again, shutting again... and nothing on the monitor. So I think after the fifth time I have shut the computer, I pushed power button again and voila: ASUS screen.

9 days passed since I buy the computer and parts were assembled by technicians. There was no problem for the first couple of days. Screen never goes off when i am using it. And only for one time, I got a warning on ASUS screen. Something like that: "VGA card is not supported by UEFI driver."

Your ideas will be very much appreciated.

Weird.
Is it the same if you insert the card in the second PCIe slot?
Can you borrow a different graphics card, just for testing?
What power supply using?
May 6, 2013 6:20:02 AM

Hi it just gets weirder,

I was writing previous posts from that computer. I have shut it down to try what you have said. Pushed to the power botton to check again, without doing any changes, but computer didn't start. Nothing happened. I have pushed that button for at least 10-12 times, shut power supply's current and opened again, but nothing happened. Mobo's led light is continuously green. 1-2 days ago something like that happened for once, but it started after 2-3 pushs so I didn't think it can be a hardware problem. I thought I could'nt push it rightly.

Power Supply is Thermaltake litepower 700.

I'm brooding on now. :( 

UPDATE: It works again. I don't understand why...

When pushing the power button for starting the board, are the fans spinning?
May 6, 2013 7:18:15 AM

Do you mean the last time that it compeletely failed to start? If so, the answer is no. Nothing happened. Fans didn't start to work, and i didn't hear any sound from the case. Only thing that showed me there is indeed electricity, was the mobo's LED Light.

If you mean my first problem. It was the opposite. Everything worked as expected, no weird noises etc. But monitor didn't display anything.

I know i'm keeping you busy. Sorry for that. And thanks a lot.

No problem.
Shut down the system, unplug from the motherboard the two wires corresponding to the case power switch and start the board by shortly touching with a screwdriver the 2 pins where the wires were connected (it's what the power switch does).
If still the no go, reconnect the wires and insert the card in the second slot. See if still the same.
It might be a power supply issue. Can you borrow one for testing?
May 10, 2013 5:29:49 AM

Hi,

Sorry for late response. These two problems have disappeared now. It's fine. I didn't make any change, except controlling the connectors on mobo. If it will happen again, i will surely follow your advices.

Thanks!
