Built another system the other day and it worked all well and good but for some reason, it sometimes doesnt want to boot on the display past the starting windows screen. Sometimes not even making it that far, just coming up with the bios promt screen. The PSU was taken from a working system which has only been had about a year and everything powers up and turns on in the system, including all the drive I can hear spin up and the front pannels I have.

RAM is recognized when I boot up and in the bios so doubt thats the issue.

CPU was fitted checking all the pins in advance because I was a bit paranoid I would mess it up :p

Green LED on the board is on.

Seems just like I cant see it? When it does make it to the display, the system recognizes everything and it works like a dream! Despite the red light under the sheilding, this being a DRAM issue light from what I gather? But the RAM is fully recognized upone boot???

Using a graphics card which is fully working and the latest drivers have been installed in safe mode. Tried the board HDMI and it makes no difference, just kinda seems like an intermittent problem with no obvious source. Once it wouldnt boot past the starting screen from the board but would from the DVI on the card and viceversa. Used all available posts except the displayport im pretty sure i have. Like I said, they are all successful but not all the time?

To clarify, when I say wont boot past the windows screen, I mean that it wont proceed to the windows login screen and the signal to the monitors are just lost. Have 2 monitors and tried each and both in various ports. Like I said, it all works, just not all the time. The DRAM light confusing me because there seem to be no issue and I always get to the ASUS initial bios prompt screen from which i enter the bios and see the RAM.

Not sure what else I can add?... just doesnt seem to be a consistent problem which is making it harder to diagnose. Will flash the CMOS when I get home (out atm) but not sure that would fix the warning light as the RAM is fully funtional.

All parts except the CPU and the mobo have been tried and tested with no error in another system.

Any advice? Use this site all the time but thought for once I would straight up ask instead off trolling through searching for answers.

Thanks.
 
Try the RAM in different slots. And keep an eye on the red light. Or borrow a known working stick from someone. This is the problem with a single stick.

Check the RAM stick with inbuilt Windows memory diagnostics tool or with http://www.memtest.org/

And to test the MB take out RAM stick, and start the PC, listen for beep sound, if its beeping(MB) then its ok, if it doesn't then I am afraid its gone.

I have more than 1 but using 1 for this purpose and 1 in my older system. When I got home all the red lights were off? No idea why but they were, maybe it realised its mistake? For whatever reason, that seems to have sorted itself.

Fitted a different speaker onto the motherboard and it does the single post beep to indicate its good on boot. I have pretty much done nothing but troubleshoot for about 10hrs now and started to look more into windows than the hardware. Saw similar issues in a bunch of windows forums but none of those fixes worked. Then realised that its consistent after I update so am now trolling through the 150+ updates until one wrecks the system.

The advise is much appreciated still. Like I said, no idea why the RAM issue is no longer an issue but then I don't quite understand why I am having any of them :p Ran memtest on the RAM 6times and its good. Would do more but feeling pretty confident as it was taken from another system where it was checked as well.

You seem to know your stuff rom your profile so was wondering if you could answer something else that came to light whilst troubleshooting. I have a GTX 660TI SC'd 2GB. The thing I was wondering is there any chance of an issue with it being in the second PCIe? Its meant to be a similar speed but I've read a lot of contrasting stuff about this. I physically cant fit it into the first slot due to the size of the heatsink but if I HAVE to, will turn it round.

Thanks again for replying.
 
So it seems like you are up and running again good. And it looks like all the components are fine. So it could be some issue related to software/driver. If you are still having some problem try to repair install OS, sometimes it can do wonders.

Try to run CHKDSK from CMD, it would help if there are some file system error. Or try to update BIOS.

And lastly please post your full system specs when starting a thread, it will help us understood better.

Oh, I almost forget the GPU thing, is the MB's second PCI-E slot runs at x16 speed ?

Yh, the second does run at x16 but ONLY when there is a single card which is the setup I have chosen. Re-arranged the fans on the heatsink though to allow use of the 1st slot. I did end up solving it in the end but for some reason tomshardware didn't notify me that this thread was still running?

Either way! I just recently discovered it MAY have been the VGA drivers on the board. I didn't select them to be installed, nor saw them in the optional installs but that kicked in the issue again. Coincidence maybe, not sure. Either way, I left them out because they must have clashed. When I was trying to fix it I did run the CHKDSK and it didn't help as well as all the other stuff you typically try. I personally however stay away from updating my BIOS whenever possible. Its the ABSOLUTE last resort for me personally.

Do you by any chance know if Corsairs macro/driver software or Razers Synapse/drivers clash with Gigabytes Ghost engine? Having issues with this mouse I bought; M8000X and Gigabyte aren't responding.
