Question PC froze while gaming, now getting "No signal input, going in to sleep mode" on screen ?

[Kodakx86]

Hello everyone,

PC model: HP Omen 880-135nd Desktop PC with an i5-8400 and a GTX 1070.

I was gaming when my PC froze completely and I had to hard reset. After doing so I started my pc back up and the monitor shows
" No signal input, going in to sleep mode ".

Also after about 90 seconds the PC will shut down and start up again. It does this once and then stays on, without any beeps but also without display.
All fans are moving including GPU.

Things i've tried :

*clean the insides of dust

*remove ram/gpu/hd etc and put them back in

*hooking the monitor to the onboard video, same message 'no signal'

*hooking my pc to the TV, same message of no signal

*switching out my HD/SSD to see if either is faulty, no results

*resetting the CMOS battery

*tried another GPU to no avail

*tested the GPU/HD/SSD/monitor on another system and they all work

*removed the RAM and started back up to see if i get any signals from the motherboard, I do. It will beep

*tried a different power supply to no avail

*removed, inspected and returned the CPU


The thing that stands out to me is the automatic reboot after 90 seconds. It goes off for like 1 full second and back on again, just once.
Anyone have any idea/suggestions?

Thanks for any help

Full system specs, including PSU make and model (or part number) is? Also, how old the PSU is, and was the PSU bought new or used/refurbished?

Take out your GTX 1070, completely, and hook monitor to MoBo.

If you get an image - your GPU is toast.
If you do not get an image - one of the following, or all of them, are dead: CPU, MoBo, RAM, PSU.

All things mentioned I have tried. The GPU/PSU work in another system.
When I take out the GTX and hook to the onboard nothing happens.

It's a HP PSU 500W, part nr : 918585-001.

Its a prebuild HP omen pc that was bought new 5 years ago.

Mobo is HP MS-7A61 cheers

Based on the MoBo specs, namely due to it's age, i'd say MoBo is toast. Most likely killed by the crap PSU you have in there.
PSU specs: https://www.cpumedics.com/hp-918585-001-500w-power-supply-80-bronze-plus-for-omen-870-envy/

30 day warranty with a PSU - the shortest warranty i have ever seen given to a PSU. Or when you pay extra, up to 1 year. Heck, that PSU can't even be sold in EU since here, 2 years of warranty is bare minimum by law.

So, what you're looking at, is completely new PC. No point wasting money on another Intel 300-series MoBo. Since if you get new MoBo, you have to buy new PSU too. Better get new CPU-MoBo and PSU combo. Oh, new PC case too since the one you have seems proprietary. The rest (RAM, GPU, SSD/HDD, case fans) you can reuse, IF you get Intel 700-series MoBo that supports DDR4 RAM. Else-ways, new DDR5 RAM too.

Thanks for all the effort in your reply, strangely enough I did buy it in EU (netherlands). I took it to a repair shop this morning so will have to wait and see what they come up with. Guess that's the risk with the prebuild systems? They put certain parts that don't directly influence performance in there that are crap quality... 😔

Prebuilt systems have a lot of issues. E.g mismatched parts (Intel K-series CPU with any other MoBo, except Z-series). Or only one stick of RAM (resulting in single-channel). PSU is often cheaped out since most people doesn't care about it. But what they do care about, are CPU and GPU. But even then, i've seen prebuilts where GPU is way too beefy compared to CPU, or vice-versa.

All-in-all, prebuilt system will cost you more than DIY (buy as separate components, assemble by yourself). Also, you can't personalize prebuilt. And depending which one you buy, you could be stuck in terms of component upgrade as well (Dell is worst in that regard).
