Inspiron 5676, Troubleshoot startup issues
My inspiron 5675 5676 shut off suddenly late one night. I was pretty tierd, so the details are a fuzzy blur. But I remember the monitor lost a signal but I could still hear the fans. I dont recall what (if any) lights were still on at that point. I think I tried pressing the power button to restart it, but I dont remember exactly. I do know I eventually pulled the plug and waited a minute or so, then plugged it back in to see if I could get it to reboot. Nothing happened so I left it for the next day.
I opened it up and the fans were very dirty. I usually clean them every so often, but it has been a while. After a careful deep clean the computer still won't turn on and I can't pinpoint why. Here are some things I know:
-fans were dirty but are clean now. They turn on fine when the power button is pressed as well as when the PSU test button is pressed
-the PSU led light is solid green when I press the test button and flashes when I try to power it up.
-when I first try starting up the computer after unplug and replug, the power button has no lights. I press it again and there is a lot of what seams like random amber flashing. Eventually it settles on 2 flashes (no RAM dected?)
-it was upgraded to 32GB (2x16) RAM about a year ago and seems to have been running fine. I even tried replacing the old original RAM to see if it would start and got the same issue.
I have not replaced the little nickle battery. But I did take it out and press the start to try to reset things.
Update:
-I tried removing the CPU to reset things and after that the fans had trouble starting. An hour later they run fine both on startup and the PSU test.
-The power button has no lights either now.
-None of the interior blue lighting comes on. (It did come on at one point before i removed the CPU, but I don't remember what I did to achieve that)

BTW: Read this thread about PSUs for Inspiron 5676. Maybe it will give you the answers you need...

Why did you remove the Ryzen CPU to fix "startup issues"?
You need to carefully reinstall the CPU in its socket, lock it in place, apply fresh thermal paste and reinstall heat sink and processor fan. Then install a fresh motherboard battery.
Now run the PSU BIST according to the instructions for a PC with a PSU test button.

Done. The BIST test failed after doing that. I got a new PSU: Thermaltake SMART 700W
Turning the computer on everything seems to start up (fans work, blue led light is on) but the monitor has no signal and the keyboard doesn't light up. There are also no error codes flashing, just solid white.

Sure the new PSU is compatible with this PC model?
Sure you reinstalled the CPU correctly, locked it in place, applied fresh thermal paste and reattached the heat sink?
Sure you correctly reconnected the cable from new PSU to motherboard and didn't accidentally disconnect something in the process? Did you reconnect the CPU power cable and CPU fan cable to motherboard? Double-check all your connections.
Do you only have onboard AMD Graphics (HDMI) or do you have an add-in video card too? Assuming you have one, make sure the video card is correctly seated in its slot, and monitor is connected to the add-in card. Double-check video cable connection at both ends too.

If you have a GPU card, try it without in case the card failed.

Honestly, I don't know. how would one find out?

Yes!
Sure you correctly reconnected the cable from new PSU to motherboard and didn't accidentally disconnect something in the process? Did you reconnect the CPU power cable and CPU fan cable to motherboard? Double-check all your connections.
All cables are just as they were before. I took pictures before just to be safe. Everything is in order. I even went back through to make sure they are all secure.
Do you only have onboard AMD Graphics (HDMI) or do you have an add-in video card too?
As far as I can tell, there is only a video card. I don't see anywhere to hook up the display up directly to the motherboard (if that's what you mean by (onboard graphics)
Assuming you have one, make sure the video card is correctly seated in its slot, and monitor is connected to the add-in card. Double-check video cable connection at both ends too.
The graphics card is seated firmly in the PCIe slot and hooked up to the PSU. I've checked the video cables and they seem ok. The HDMI hook up on the Video card felt loose, but I also tried hooking a monitor up to the DisplayPort and it still found no signal. All the monitors/cables I tested work fine on other computers.
I'm curious as to why the keyboard isn't even connecting? At what stage of turning on the PC does it try detecting the keyboard? Is it not getting that far?

Should look for keyboard during the POST (power on self test). Try a wired USB keyboard and try both USB2 ports next to the Ethernet port.
Onboard AMD graphics HDMI port is on the rear black panel of PC. Add-in video card would be in area marked #6:

@RoHe there is no HDMI port there on mine:
As far as I can tell, the only way to connect a monitor is through the video card.
P.S. the mouse and keyboard are the two USB cords in the pic
P.P.S. Apparently it is a 5676, not a 5675

@bradthetechnut My problem that is the only way to hook up the monitor is through the video card.

@thaslam -You told us this is an Inspiron 5675 and the image I posted is for that model. So it's really an Inspiron 5676...duh!
Inspiron 5676 motherboard has two M.2 slots, one for an M.2 NVME SSD (#6) and one for a M.2 SATA SSD (#17). How many SSDs do you have installed, and are you sure the correct SSD is in the correct slot?
There are two PCI-e x16 slots on this motherboard. Are you sure your video card is in the right x16 slot? PCI-e x16 slot #23, closest to the CPU, is labeled as the graphics card slot. So make sure it's correctly seated in that slot.
Are you sure your video card (which one?) is working? Even if its fan spins, that doesn't mean there's video output.
Have you tried connecting keyboard to any of the USB3 ports above the rear USB2 ports, or to any of the USB ports on front of PC? Does your keyboard work on another PC?
Is it time to take this system to a local repair shop?

@thaslam
That was going to be my next suggestion - try a different GPU card if you can.

@RoHe there is no SSD in either slot.
The GPU is in the first PCIe. It is Radeon brand, but I don't see any other identifying marks. Here is a pic:
Keyboard works on other PCs and I tried a working keyboard from another PC in various USBs and nothing.
I have a Radeon RX580 from a newer computer I'll try this afternoon.
Some question I still have before we give up: doesn't solid white mean it finished POST? And if that is the case, why would it not be recognizing the keyboard at least?
Also, if I put in the other VideoCard, will it still recognize the display without the proper drivers and such?
Is there any way to plag in a display without a video card? If that is the only way, does it need to be a specific video card (like an origional)?

Before you swap GPUs, test this monitor and its cable on a different PC. And if you have an old-fashioned PS/2 keyboard, unplug USB keyboard and connect PS/2 keyboard via purple PS/2 port on rear of PC and see if that works.
No other way to attach another monitor than an add-in video card in this PC. If the one you have is in x16 slot closest to CPU, try the other x16 slot with this one and/or that RX580.
I see from your pic the current GPU has a power cable plugged into its top edge, presumably coming directly from the PSU. Does that cable have the exact same 6- or 8-pin connector config as the socket on GPU?
Is your boot drive a SATA drive in a drive bay, and either an HDD or SSD?
Solid white power button usually means it passed the POST, but all that means is it didn't find any significant internal problems. Doesn't mean there isn't a problem with external hardware or with getting power and signal from internal hardware to external hardware (monitor, USB keyboard).

@RoHe I've tried this monitor and cable on another PC and it worked. I also tried the other monitors and still no signal.
I've searched for an older keyboard and haven't found one yet. I'll keep looking over the weekend.
I moved tried both GPUs in the second slot and nothing changed
The current video card is 6 pin the rx580 is 8 the PSU has both options (a 6 pin that has two pins that can be added to it tomale an 8 pin plug) I've tried both the current GPU with the 6 pin and the RX580 with 8 and had the same result as before.
I assume it's booting from this drive here:
I took it out for the picture, but it was in the drive bay.
Thanks for the clarification on passing POST vs initiating the keyboard/monitor.
This begs the question, is it a problem with the compatability of the PSU? Is the only new component. It has the same roots of cables as the old PSU, but I don't dose that guarantee compatability necessarily, does it?
I really don't know how to verify its compatability either way though. I spent several hours looking online for compatability info and didn't find much. (But I wasnt sure what I was looking for anyway). Here are the specs from the box:
And the whole box (just in case it's useful) :

Sometimes aftermarket PSU's skimp power on the 3.3v/5v rails as compared to Dell's. This even though they boast more total wattage. Compare the amps and watts on those rails as compared to the Dell PSU. Current should be just as much, if not more, than the Dell PSU.
The caveat with that is Dell's label won't list those if the MB has an 8-pin connector instead of 24-pin. If it's 8-pin, then only 12v rails will be listed. I take it you have both connectors plugged in to the MB, whether it be 24-pin + 4-pin or 8-pin + 4-pin.
