Question PC seems to be booting up but no display and both mouse and keyboard are not lighting up

[cloe1994s]

I have been having the weirdest problem I have ever encountered dealing with my computer.
So I have an old build i5 2400 8GB of ddr3 Ram , two hard drives a 1TB Segate and a 320gb Hitachi all running off of an OCZ CXS 500w psu and plugged in to the Asrock H61m VS motherboard.
My problems started once I sold my GTX 650ti boost Graphics Card which I had for years running in that build.
As soon as I took it off the system and gave it to it's new owner I tried to boot up off of the i5 2400 integrated graphics which worked just fine and I was able to boot normally and even watch some netflix but after 30 minutes or so the screen went blank (NOT BLACK) it was still lit up but there was nothing on the screen. I tried to move the mouse, clicking CTRL ALT DEL... nothing worked so I shut down the pc and boot it again and there I couldn't for the life of me get it to post.
So that's what I got: All the fans are spinning , hard drives are spinning and even the led's on my back chassis fan are glowing but my monitor is not turning on at all.
I can see the blue led in the lower right hand corner blinking constantly but the monitor wouldn't turn on. I tried to force turn it on by holding its tactile button for a few second then holding it again but that didn't work. My monitor is a 22 inch Samsung S20A300e it has a VGA and a DVI ports in the back.
My motherboad supports VGA only but before I sold my graphics card I was using a VGA to DVI adapter to plug in my 650ti boost and VGA to plug in my monitor which worked just fine.
What I have tried for the last couple of days:
-Resetting the ram / trying to use one Ram at the time
-Removing the CMOS battery leaving it for 5 minutes and holding the computer's power button for 30 seconds then putting the battery back in its correct place
-Changing the CMOS jumper's placement from pin 1 and 2 to 2 and 3
-Trying to use a graphics card (Gtx 1650) which I borrowed from my cousin and running it with a HDMI cable with a different samsung monitor which has an HDMI port (NO adapters)
-Trying to boot without any hard drives attached
After trying all of this nothing worked permanently, I have been able to enter the bios on a couple of occasions and I enabled the IGPU multimonitor setting and I even got into windows and was able to use the pc normally browsing the internet all using my VGA cable directly plugged to the motherboard and my sansung S20A300e VGA port.
But after I shut down my computer last night and wanted to boot it up this morning I got the same problem PC is seemingly booting up and all the fans are spînning but I got no display on my monitor, also my mouse and keyboard are not lighting up either.
All help is appreciated.

Have you tried a new PSU? I can't help but wonder too, if some component of the PC got "disturbed" when you removed the GPU, and now the PC is acting up.

Re-seated the RAM yet?

Thank you for your reply and merry christmas.
No i didn't try a new psu because i don't have a spare one :/ although this is what i am thinking of doing as my next step.
Yes i already re seated the Ram and tried them one at the time but no luck.
It is also worth mentioning that in the few times that i was able to get the pc to boot up and show the windows logo i got a blue screen with stop code : inaccessible boot device.
I have attempted to fix this by going to troubleshoot in the advanced option menu and chose the reset option which took a while but did indeed help me get into windows successfully but after a reboot i went back to square one with no display.
Also when i successfully booted another time (after many tries) i got the same blue screen again even though i thought it was fixed earlier.

I'm starting to lean towards either a power supply or a motherboard issue here. I agree that your next step is to replace the power supply.

What version of Windows were you running (7, 8, or 10)?

Update: i went through and tried unplugging every single cable in the motherboard and re-plugging it again.
Now i am getting an error beep code which is 5 consecutive short beeps i initially thought this was the ram code but after re seating the ram modules and putting them back one at the time i still get the same five beeps. I am lost! please help.

5 beeps could be no display, try a different cable.....

 

[Steltek]

5 consecutive short beeps on an AMI BIOS is a CPU error. However, it doesn't indicate whether the actual source of the error is the motherboard or the CPU (i.e. a bad motherboard can also cause it to throw a CPU error even if the CPU itself is good).

5 consecutive long beeps is the AMI beep code for no video card detected.

These kind of problems are tough to pin down; let's try a few things before calling the board nerfed. Though that is a strong possibility given the age of components.

Replace the CMOS battery. Remove the board from the case if you have not done so already, and try to boot barebones i.e. just ram and CPU, no drives etc. Next up: How were temps? Were they even checked? Ever reapplied thermal compound on the CPU? CPU fan is spinning? I would redo the thermal compound and reseat the CPU. Also discharge the caps with a screwdriver by shorting the power switch pins, before trying to boot barebones out of case. If none of that works, the board is likely nerfed. That, or you have a less common failure, the CPU itself.

If you managed to get it to boot again, immediately flash the bios.

I have actually took the whole pc to a friend's house so we can diagnose using his parts.
Results: My psu is fine he tried his and it yield no difference.
He tried his RX 580 in my system and it worked fine although we couldn't try the on-board VGA port in my motherboard because he had no monitors that have VGA in them only HDMI and DVI :/
Also the beeping sound (5 beeps) continued to happen before the one beep posting sound.
Now I can get my keyboard and mouse to lit up as normal and hear the 5 beeps followed by the post beep and eventually my pc boots up to windows however I cannot see anything on the screen as usual using the VGA cable directly from my motherboard to my monitor.
Seems like the only way to see an image is by using a dedicated graphics card in the PCIE slot.
My guess is that I need to enter the bios and change the allocated memory for the on board graphics from Auto (default) to another figure because according to my motherboard's manual setting it to auto disables VGA.
The second theory is that the VGA port is physically damaged.

This may sound dumb but I had a strange monitor issue years ago.
Does your monitor have different modes? I had a gateway monitor that was kind of like a TV with different modes for different plugs. You had to go thru the menu to select analog or component or dvi.
It was changed to something else and the damn monitor wouldn’t display anything

Sorry for the vague response this happened a long time ago.

 

[cloe1994s]

My monitor is a 22' smasung S20A300e it has both VGA and DVI and yes i do have the option to switch between Digital and Analog.
I noticed that the No display problem is present whenever i am trying to boot using VGA cable and have the option on Analog but when i switch to digital i simply get the Check signal cable message bouncing around the screen. I hope that helped.

I think you have it right with faulty VGA port or cable. If you get in the bios, make sure you set onboard to initiate first if your's has that setting.
