Question Windows 11 boot loop

[raeanthony]

Hello, I tried to turn my PC on and it just kept turning on and off without showing any display, this is an old PC that's been working fine. I tried to access the BiOS but it wouldn't let me. I saw online that taking the ram out and putting it back in solves the issue. I tried that, the machine stayed on but the display was not showing up. Somehow it reverted back to the boot loop. As I was looking for the CMOS battery (which I still cannot find), I saw that there is a red light on my motherboard, the light is for VGA. Is my PC toast?

Thanks in advance

Edit: I took the GPU out and tried to use onboard graphics. Still stuck on bootloop and now I noticed the CPU light is also going off while the VGA red light disappeared.

Here is a video of the lights on my CPU.

Using onboard graphics, can you access the bios now?
When did the boot loop start? e.g after an update, software install, driver update etc.

No, I cannot. Still stuck in a boot loop. The video I posted is when the GPU is out and using onboard graphics.

Did the boot loop start totally random?
Can you take a pic from above of the motherboard and post here?

Yes, last night it was working fine. One thing though, my copy and paste wasn't working last night so I restarted my computer and copy and paste started working again. I shutdown my PC during the night. This morning I turned it on and here we are.

I'm not too sure what you mean by top of the CPU.

It's not good that you can't access the bios at all. If you could, a windows bootable usb would have been worth a try to run scans etc. but you need bios access to select the usb device as the boot drive.

You can try just trying one stick of ram (swap if needed) and unplug all external devices and extra hard drives if any. See if it boots and let us know.

Would it be worth bringing to a computer shop?

You could try the above to boot from a basic system. Unplug all drives and externals, leaving one stick of ram and onboard graphics, then boot to see if bios works.

Yeah, I've also tried the ram thing. First time I tried, the display booted up and there was some white text on a black background but my computer forcefully shut off before I could see the message, after this it just loops back.

I have 2 ram sticks and I checked each individual ram slot, only inserting one for each test and still no good.

As I was looking for the CMOS battery (which I still cannot find),

The battery usually gets hidden under the GPU and hard to see.

Without knowing the parts your running all I can do is guess.

Un plug the PC than hold down the power switch for 20 seconds to drain the caps in power supply.

Remove the GPU and see if you find the battery. Use caution to remove battery so you don't break the holder.

Use a volt meter to see the life in battery. If not 3.0v it's time to replace. You can usually get them at Dollar Tree or order on Amazon.

This is at least the first step before going ape and throwing money at parts.

It very well could be a bad power supply but again we have no parts list your running with.
