Hello,

I am having issues with my pc. The problem is that it's not starting to boot.
No peripheral units (no rgb on mouse,keyboard). No monitor response. Stays off.
No signal when turned on manually.

The VGA debug light turns on during startup. All led's light up (even gpu ones).
I've tried every single thing the internet suggested doing. To list them:

-Check connections
-Second display
-HDMI in mobo and secondary HDMI
-Secondary GPU
-Secondary RAM
-CMOS Drain and Checked battery with instrument (3.3V)
-Secondary PSU
-Tried to flash back bios but it wont even go to the point of reading it

Nothing seems to work. If someone has an idea what else to try or maybe
pinpoint the fault. My best guess the mobo broke? (weird)

The problem started one morning when i started it up. (the night before took long to shut down
didnt think much of it).

The things ive done recently:
-Updated BIOS (ordered a new cpu, it comes next year bcs of shiping problems), 7B08v1K5(Beta version)
-Updated Windows to 11 (its not compatible with my cpu but internet said its fine)
-Better GPU and a bit of stable OC (149Mhz)

The pc was working fine for a couple of days with the stuff done to it.

My hardware (7yrs old)
- MSI B350 Krait Gaming
- AMD R5 1600
- GTX 1070 (tried my friends 1080ti)
- evga 500W
- corsair vengance 2666Hz 2x8
- 250ssd kingston

Thank you for any response in advance im desperate.

A no signal message normally means that the screen is fine and that the issue is with the source of the video or the cable that carries the video signal from the source.

Try your GPU in your friends computer and if they are real generous ask them if you can borrow their PSU to test your system.

PSUs don't last forever and chances are that yours should have been well replaced by now.

Gaming rigs must have a minimum of a Gold efficiency rated PSU that has enough output to support the whole system, even when out of the box new a 500W PSU would not be expected to be able to safely power your friends 1080Ti as they require a minimum of 600W.

You will not get any video from this as for the MBs video ports to be able to work the CPU must have on die video and your CPU doesn't.
 
i've also tried a rx 580 and in both pcie slots. No reponse
The PSU should be fine since i've already tried replacing it. No response.
Next step should be to replace the mobo but since i dont have a spare on hand cant do that. is it posible to check the pcie slot is working using an instrument? Ty
 
Your computer to do with as you see fit but why ask for help on a tech forum and then ignore what is suggested :unsure:

Is the EVGA 500W PSU the original or the replacement.

What are the brand, model name or number and age details of the other PSU.

A home user does not have the equipment to be able to test a PCIE slot.
 
it wasnt a shop. It was more of a workshop. i took the pc there and said if they could replace the PSU to see if its broken. They said they switched out the psu and it didnt fix the issue. They didnt want to investigate further since the owner was a cocky intel fanboy and said ive broken my pc by updating bios but i dont think thats the issue at all since the pc doesnt even pass post. I will now short the PSU and measure voltages just to be sure.

A less than useless test and while you don't think much of the intel fanboy what makes you think that he was wrong.

The attached videos are the ones that I use as an example to show the sort of equipment that is required to conclusively test a PSU + what can happen when testing cheap and nasty PSUs

What the equipment does is simulate a computer under load and so the PSU behaves as it would when it is powering your PC, multi-meters and the basic testing devices that you can purchase from some merchants only test the basic voltage output from the PSU rails and so cannot be relied on as 100% conclusive.

So what makes you think this is a PSU issue?
And i've already explained what makes me think he was wrong:
(broken my pc by updating bios but i dont think thats the issue at all since the pc doesnt even pass post).
Please correct me if im wrong and that totally is posible in that case why did it work for 5 days and then failed?
And please tell me what should be my next step of doing?
Ive talked to my fried with similar PC and we are going swap components one by one. What should be order of switching for optimal troubleshooting. Thank you very much for all of your replys so far kind sir.
 
No one here has said for sure that swapping in an appropriate PSU will do the trick but the PSU is the most important component in any computer because like the human heart it needs to be strong and stable.

Add to the fact that you have been using a dangerous PSU and you are looing at two possibilities, the PC has taken out the MB and possibly other hardware.

A computer will not pass the POST if the BIOS is bad and nine times out of ten you will only get a black screen.

Already advised as to what you need to do;

If your GPU works in your friends computer that can be ruled out as the cause and the next step would be to put your GPU back in your PC and swap in the PSU from the computer were your GPU worked.

You are welcome and good luck (y)

NB: Not going to be around until tomorrow UK daytime now.
 
Will be trying that after the holidays.

On the side note i have connected a speaker on the mobo. It gives 0 beeps on boot with graphics card and 1 long 2 short when i remove it.

Hope this information helps in anyway.

Happy holidays
 
Hello,

As I had some free time today and cant sleep at night because of me not being able to fix my pc I called up a friend.
We tried swapping my gpu into my friends PC. The PC went past boot with no issues at all. Loaded up windows and all.
The next step was taking his psu and hooking it up to my pc. HIS PSU:

VP600P - ANTEC

www.antec.com www.antec.com
Still no response.

Whats next?
 
Will come back to the troubleshooting but first of all a question for you, what originally happened as in was the PC in use and it turned itself off or was it dead the next day after being fine when Windows was correctly shutdown.
 
Strange :unsure:

A quick test for you to do;

Put the GPU back in the primary PCI-E slot and make sure that the 8 pin supplemental power dongle from the PSU is connected.

Remove both sticks of RAM.

Attach the keyboard and power cord.

Power up to see if you get any error beeps then post back with an update for us.
 
That means that things are ok up to the point that the video card gets tested as part of the power on self test.

Can I just ask you to confirm that you are still using your friends 600W PSU, our testing relies on it.
 
Im afraid that is no longer possible since my friend left with it as he needs it for work.

Although im fairly certain that my psu is functioning properly since it shows no signs of damage and has founctioned properly for the past 7 years.

P.S i've already ordered a new one higher on the list you sent

You have been provided with independent proof as to just how bad the PSU is, it is four years out of warranty and you have ordered a replacement yet you dismiss the present supply as being at fault, strange :unsure:

Shouldn't have been done until our testing was completed so no point in continuing here now, we will just wish you good luck.
