I have been battling this problem with my PC for months. All my fans turn on, my HDD, my disk drive, CPU fans, GPU fans, CPU, GPU. But my keyboard and mouse don't connect and my monitor receives no signal. After turning on and off my computer a bunch of times it will start up and everything will be fine. A week or two ago I moved one of my case fans to be powered by the mobo vs directly from the PSU and it stopped the problem up until yesterday. I have been researching and testing different methods of what to do to fix this but obviously nothing has worked. Also I usually always put my computer to sleep, and this problem usually occurs upon wake, but it happens when I am turning it on as well.

Please tell me who makes your PSU.
Also try booting with the HDDs, Optical drives and GPUs.

You probably need a PSU.
To check the other components first remove everything but the CPU + cooler, motherboard, PSU and RAM
Does it boot?

That's the thing, last night I was stability testing and my PC has been on for over 16 hours. And I was adjusting my overclock before that with constantly shutting off and turning on to apply the overclock and it didn't do it once yesterday. It only seems like if I don't use it for like a day it does the everything turns on but nothing connects and no picture thing. I don't understand why the problem is not consistent at all.

Overclocks can cause these issues. Does it work fine at stock speeds?

No, it does the same thing at stock. It actually seems to do it less often when its overclocked which I don't understand at all.

That is weird.
have you tried with the HDDs unplugged?

I only have one and no I haven't, wouldn't it just boot straight into bios without a HDD plugged in?

Another thing that may be linked is when my computer sits idling for too long (maybe an hour+) or is downloading a multi GB game, it BSODs and says its because of a wireless adapter driver.

You could try without your WiFi card / Wireless adapter.
(If it a motherboard WiFi adapter disable it in BIOS)

I'm speechless, my PC has been on for 24 hours with a 7 hour stress test at the beginning.

The only thing that is different than before is that I bumped my core voltage up yesterday. Maybe my voltage was too low and now I am 100% stable on my overclock with no failed tests in Prime95 for 7 hours. So maybe the instability was the stock core voltage was too low, which doesn't make any sense.

Ok, so I just tried to start my PC before I left for work and it wouldn't boot. When it finally did boot my ref clock was 194 and my multiplier was 15.5 so it screwed my OC up. But the next time I boot it, it will be fine because it has done this to me before.

Could be the PSU giving bad voltages or the motherboard going mad. Those are the main suspects.

Yeah, probably. Its just gonna suck if I replace one and then the other one is bad not the one I just replaced.

No I do not. And it seems like every time it starts up it has problems but once it starts correctly its fine and car run for at least a day without shutting down. Its like it needs to warm up before it will come on correctly.

Ok. Tell me what you do decide to replace and what happens. If you replace the PSU and it's not the PSU at least you've saved yourself from a cheap and potentially dangerous PSU.

Yeah i know, its not the PSU I would have chosen. I bought this PC from my buddy and have been upgrading things and like the only two things that are the same are the MOBO and the PSU lol I was wanting to upgrade the MOBO for a while but I have been wanting to see if the next gen of AMD 8 cores are gonna be completely different socket and architecture or if they are gonna be the same. But I picked out a new PSU on my lunch break today and hopefully I will be able to replace that soon.

Good. Just make sure it is a SeaSonic, Corsair, XFX, Antec or other good brand.
As for waiting for the next gen 8 cores, you do know that the Intel I5 gets higher frames on most games than the 8 core AMDs. This is because the AMD CPUs are 8 weak cores yet the Intel CPU is 4 strong cores.

Ok so it has almost been a week since I got my new PSU and the problem didn't happen again till yesterday. But is was not as bad as before. Before it would take forever to get it to start up properly but is just took a few tries and it booted fine. It comes out of sleep mode and everything.

I guess the motherboard is bad then (or at least a bit dodgy)

To be honest, it only seems to happen when its cold out.

My bet would be dodgy solder on something (it heats up and makes contact??)

I should see if it's a bad solder somewhere because I can just re-solder it and be fine.

I mean the solder under the Chipset / GPU etc..

Does it work fine with a different GPU?
