PCSPECIALIST Tornado R9XS Gaming PC - Powers on but no display

Hi everyone,

Had my PC since May this year.

Everything has been great (had a little niggle with the RGB lighting but was resolved after I posted here).

Early hours of Saturday morning, we had a power cut. Later that day, i tried to wake up my PC (I never turn it off) but it would not wake up.

So I switched it off/on but nothing would come on the display. All of the fans / rgb are on but nothing comes on the display.

I opened the case and checked all the cables were secure. I tried the reset button on the front of the case but it didnt help.

I took the GPU and 1 RAM stick out and tried to start it ( I plugged the DP in to the onboard port) . No beeps were heard and nothing on display.

Finally, I unplugged everything and also took out the CMOS battery.

When i came back after 30mins, I powered it on and my heart stopped when i saw the ASUS logo on the screen !!!!!!
I could see the message that BIOS was reset (i entered the bios and could see the clock was set to 2022). I did a CTRL-ALT-DEL and the system restarted and booted in to Win10 !!! - all my files etc were intact.

I then powered everything off, put the RTX 4090 back in and the CMOS battery. However, I got the same (no display issue again)

I thought maybe the CMOS battery was duff, so I got another C2302 battery and put that in but again, nothing on the display.

I took the GPU and CMOS battery out again but nothing on the display. I left it for an hour but still same result.

Its now be 12 or so hours, there is no GPU or CMOS batter inside but every time I turn the computer on, all the light and fans spin up but nothing on the screen. The screen is on (i see the green light, where as it normally goes amber when the PC is asleep). So the PC is sending a signal but its not completing the POST.

I also tried to "touch" the CLRTC pins with a screwdriver (when the power cable was out) - should the power cable be in when I do that?

Is there anything else I can try?​


Do i need to call Currys or can I phone PC Specialist for support / RMA ?

Thanks you for any advice.

You want to do these tests with the CMOS battery in, you are only looking to reset. It's a strange issue for sure.

Everything coming on but no beep suggests a processor/motherboard issue.

I would take out all of the RAM, remove the GPU and see if you get an error beep on the POST. I guess there are no SATA connections being used? Doesn't appear so from the pic.

If you get the error beep, this is a good sign. Plug in one of the RAM sticks and repeat the process.

Add the second RAM stick, try again and then repeat with the GPU.

You need to ensure you do one thing at a time rather than multiple. Plugging in the GPU and the CMOS battery in your excitement has skewed the potential issue.

If you don't get any joy I would start an RMA process pointing to this thread to show what you have attempted. PCS will likely swap out the hardware components to see what the issue is.

Hi Scott,

Yes, no SATA is used.

I will put the battery back in and take out both sticks of RAM and try it again.

btw, i don't every recall hearing beeps - maybe the internal speaker in not connected ?

The fact that it did complete the POST once - does that mean there is a chance the MOBO could still be OK ?

Intermittent issues are the worst kind. It leaves you chasing your tail unfortunately. Anything is possible at this stage really.

If you haven't ever heard beeps then it's possible there is no speaker. Is there any LED lighting on the motherboard to indicate POST status?

Having a look at the pic I can see the little speaker attached down the bottom left (on the pic). This should be giving you a beep upon posting.

Make sure that PCS/Curry's know that the PC was plugged into a surge protector. Had you not done so you might have voided the warranty. 😉

OK, so I did

1. Put the CMOS battery back in
2. Take out both sticks of ram

(GPU was already out).

Turned system on, the lights and fan are on but nothing on display.

Its worth mentioning that in this state, the monitor didnt turn on and again, there are no beeps.

Also my USB keyboard doesnt light up - it was before.

Does this speak look like its plugged in properly:

Anything else to try or is it time for RMA ?

Thank you

What resolution monitor do you have it connected to? It may be that’s it’s booted into a BIOS window that isn’t supported at that resolution. Worth trying it into a tv or something just to see if there’s any display through that

My guess would be that the drive may have failed

Update:

Putting 1 stick of RAM in and powering the PC on, now my USB keyboard has lit up and the monitor is on again (but nothing on the display).

When you say "Drive may have failed", do you mean the NVME's ? as yesterday or last night, when the PC did boot once (with no CMOS battery and now RTX GPU in), i was able to get to windows and even log in!

I was using the onboard Displayport and have now changed it to the HDMI port - same result.

Monitors are 4k, i;ll see if i can find a 1080p monitor

With the RAM out it should fail post and identify this with error beeps and/or LED lights on the motherboard.

With it not working, it could be the PSU not sending the CPU power properly.

It would typically be the PSU that would fail in a power event. The Corsair ones tend to do a good job of protecting the system.

If you really want to get into it, remove all the PSU connections and re-connect them. If there are multiple CPU power options, try one of the other ones.

Put the RAM back in for any future checks though as it's a hard stop without it in.

Fingers crossed a 1080p display may show more

They do state that they've never heard beeps so it's likely either it's not properly wired, or just busted, so no post I wouldn't take as being an issue particularly

I can't see any specific lights on this motherboard ( X670-P Wifi) to show the POST status.

Is there an easy way to get to the PSU connections ? I did the the other side panel off but I cant see (easily) where the cables are going in to the PSU.

Everything is bound, really tightly, with wire tidy clips !!!

Update 2 (too weird!)

Called up PCS, the gentleman said that I had tried all the things he would have and thinks its probably the mobo.

RMA arranged.

He said he will ship out a box to start the process and advised I put all the bits back in (both ram sticks, RTX)..

I put everything back in and for the sheer lols, i try and power it on .............. i get display on my 1080p monitor ! - same bios warning as before.

bios.PNG


I reboot the PC to see if its going to keep working and unfortunately i get the same no-display issue.

I then think that it could be my 4090 (maybe it cant get enough power due to the surge or something or maybe its just fried 😲), So i just unplug the power to the card and restart the PC.

The PC boots again to bios !!!

This time I go to the bios and think maybe I need to make a change (to ensure that I can write changes, after changing the CMOS battery), So i change a random setting (boot up logo size!). I save changes and reboot.

Again the PC boots to bios and I confirm my change was saved.
(The reason Windows was not booting was i had taken my NVME out, as I wanted to copy some files as I thought i was sending it back to PCS).

I switch off and plug the NVME back in and restart.

PC boots to Windows 10 !!!

I then shutdown and plug the power the RTX 4090 again.

Restart and my PC still boots in to Windows 10 with the RTX 4090 all plugged in !!!!!!!!!!!!

What on earth !!!!!!!!!!!

So maybe the powercut did something to the CMOS and until i wrote a new change to it, it was not reading it properly ?

I will wait for the RMA box but I will let PCS know that I will keep using the PC and see if it behaves itself.

Appreciate all the advice and help here. Thank you

Final Update

Plugged all my devices in (usb hubs, web cam , usb speakers, type-C mic ) and guess what ........ machine has same no display issue !!

Then unplugged every device and slowly added 1 at time, ensuring the PC would fully boot in Windows, then doing a shutdown and adding the next device.

It ended up being the USB-C mic , as soon as I plug that in to the USB C port, the machine does not POST.

Maybe the surge, has borked the port so it tries to output video or something ?

For now, i can just use a USB c to usb A adapter and the mic works fine.

thanks again
