Computer attempts to wake from sleep, and then has issues

[Pyro]

Thank you very much for your help Malnutrition, all the best to you.

Bruce, when I sent my previous GPU in for service, I recall the light coming on even without the GPU altogether. (I will test against this within the next week or so).

I am interested if there is an issue in the CPU seating, I suppose a complete dismantle/repasting might be in order.

Would you recommend this?

[Bruce]

I so recommend it that I said as much in post #41.

[Pyro]

Just wanted to double check, I’m sure you can appreciate the redundancy! :LOL:

I’ll go through and test a few things, primarily whether the light comes on with the GPU out of the system, along with giving it a tear-down to the board and a repaste.

I’ll update this thread with anything I find out.

[Pyro]

Alright, I took some time to disconnect connectors, unplug the GPU, boot the system, reseat the ram, reseat the CPU, reseat the GPU and look for anything out of the ordinary.

The light still comes on without the GPU installed, i had trouble getting it to output to the monitors as well but that could very well be operator error or something of the sort, it worked eventually but sometimes it required a restart or something of that nature.

What I did find that made me raise an eyebrow, was this:

My 24-pin motherboard connector seems to have turned itself into a 23-pin connector :ROFLMAO:

I’m not sure how or why, but I can’t imagine this is normal, could this be the cause of my issues?

The unit is a Seasonic 750PX for reference.

[Bruce]

that ‘missing’ pin is pin 20 and can be the -5v pin, but in many PSU’s it is not connected.

in some PSU’s they do supply it. all depends on the ATX version.
but you may be onto something, see here; 24 pin main connector missing pin 20 | Tom's Hardware Forum

[Pyro]

I see, that post doesn’t tell too much in light of solutions, other than soldering in a new connector.

I will reach out to Seasonic for their advice and see if they want to send me a new cable or something of the sorts.

Other than that however, does this process tell you anything? The only feeling I get is that there is a possible CPU/socket issue, but, upon inspection I didn’t notice any bent pins or anything strange (other than some old darkened thermal paste.

[Bruce]

my feeling is the PSU or GPU is the primary potential reasons.
next would be the mobo or memory.

you have had better success after cleaning, and further success after a memory tweak - so right now my money is on RAM.
but that Tom’s Hardware link suggests that your missing pin20 is worth exploring further.

[Pyro]

I reseated the ram, nothing seemed out of the ordinary, the connectors looked to be clean, free of any marks or bends. (XMP is disabled for reference)

The GPU just came out of the factory after passing all standards for a refurb card (EVGA’s standards, whatever those may be).

The motherboard was sent in to ASUS about a year ago and came back clean (the light issue was happening back then as well).

I am followed up with Seasonic about the missing 20-pin just to ensure, however, it seems like it is as you suggested, along with the motherboard manual suggesting nothing about a necessary full 24-pin or 20-less connector.

I’m having difficulty trying to source myself a loaner unfortunately, at this exact moment I cannot test that unfortunately.

[Bruce]

no worries, post back in a few days and let us know your progress.

My 2 cents
Un plug computer and plug direct to wall socket
Even if you need an extention cord - No power boards
Straight power

[Pyro]

Plugged it straight into the wall, been troubleshooting and looking at that. I think I have found a power supply I could swap, but I want to re-verify that the issues weren’t caused by my surge-protector.

Wanted to update with what I currently know

[Bruce]

cheers - we love updates! (y)

[Bruce]

@Pyro - still going strong?

[Pyro]

Bruce, I am still troubleshooting. I haven’t had the issue yet, but I have found it difficult to replicate since I reset windows. To be blunt, I am unsure, still working on that warning LED as well.

Sorry for the delays, this is proving to be quite bothersome.

[PeterOz]

What warning LED
