PC not waking from Standby

[zerogear]

Not sure where to put this, if this the wrong forum, please move it.
Thanks

My PC is currently experiencing some issues when I wake my PC up Standby -- when I hit a key to wake my PC up from standby in the morning it does a restart (not a full restart, it just gets stuck in a loop, of not POSTing). I need to do a full shutdown and then turn it on again for it to turn on again.

When I do standby -> wakeup right after, it seems to go alright, it usually occurs when I put it into standby for long periods and try to wakeup.

I am wondering is this a PSU issue? -- I am not experiencing any other instabilities besides from this, and this used to be working in the past ~2 years.

I am wondering is this a PSU issue? Since it seems to be not able to handle the initial pull from standby.

Are you using a ssd? Post specs please

Mods. Move to memory?

Yes, using SSD

Intel 2600K @ 4.0 GHz (I've removed OC to see if it helped, didn't)
ASUS P8P67 Deluxe (BIOS 2001)
Intel SSD 320 160GB
G.Skill 16GB RAM
Corsair HX850 850W
5x Samsung 1TB

By standby do you mean S3 sleep or hibernate? The system shouldn't post at all when resuming from S3 sleep.

I don't think that it is a PSU capacity issue, your 850W would have to be seriously broken to not be able to handle that load. It could be that something strange is happening to the standby rail that is causing it to lose power though. Try removing any unnecessary expansion cards and all but 1 stick of RAM.

S3 Sleep. What I mean by not posting is, basically, I hit a key to start the PC back up, it would light up (fan controllers/power led), but after a little bit, everything would turn off (like it was trying to restart) and turn on again, but the screen never comes back nor does the BIOS post. And it will not show anything on screen until I hold down the power button and force a shutdown and turn it back on again.

Edit: I have an extra PSU. I'll try a PSU swap and see if I can solve or eliminate a possibility...

Next I guess would be memory

Yeah, any troubleshooting that you can do by swapping out spare parts is helpful. I'm thinking BIOS issue though. Try different BIOS versions (not necessarily the latest).
