changed PSU, checked ram with Memtest86, passed every time. Even changed the ram slots and tried other ram.

how bad is the dust build-up?
how good is the air-flow?
have you tried running the unit with the side over off and a fan blowing into the chassis?

Cleaned it just yesterday so there is no dust.
Got 1 fan for as intake and another for exhaust.
Yes, I have tried to ran it with side panels off, same thing happening

Another thing, I’ve managed a Radeon 5450 GPU, when I use it same thing happens (no power in keyboard and mouse, some times after it gets automatically shut down or a hard reset) but this time there is no solid colour in monitor instead the screen freezes.

Does [COLOR=rgb(243, 121, 52)]Start your PC in safe mode in Windows 10 and what were the results?

Have you tried a [COLOR=rgb(243, 121, 52)]How to perform a clean boot in Windows and what were the results?

Post as much as the system specification including the power supply unit.[/COLOR][/COLOR]

[COLOR=rgb(243, 121, 52)][COLOR=rgb(243, 121, 52)]
In safe mode random colour doesn’t appear but screen gets full black, then again same thing. Even if I open BIOS and leave it like that same thing happens,
Yes, tried clean boot

Is there a fan on the heat-sink for the CPU?

Is it spinning?

EDIT: You stated that you checked things did you do anything to the CPU?

Yes, there is a fan and its spinning.
No, didn’t do anything to the CPU

If I may butt in a second.

Do you see anything in Event Viewer? When a solid color like that happens, it usually indicates the GPU or another component is overheating. There’s a sure fire way to verify if it’s the GPU.

Let’s stress test your GPU. Download Furmark and install it.

FurMark Setup:

• If you have more than one GPU, select Multi-GPU during setup
• In the Run mode box, select “Stability Test” and “Log GPU Temperature”
  Click “Go” to start the test (Looks like it’s “BURN-IN test” now)
• Run the test until the GPU temperature maxes out - or until you start having problems (whichever comes first).
  NOTE: Set the alarm to go off at 90ºC. Then watch the system from that point on. If the system doesn’t display a temperature, watch it constantly and turn it off at the first sign of video problems. DO NOT leave it it unmonitored, it can DAMAGE your video card!!!
  If the temperature gets above 100ºC, quit the test - the video card is overheating.
• Click “Quit” to exit
  What you are looking for:
• excessive heat from the GPU (report back with anything over 90ºC)
• problems with the video display (picture is distorted or jumbled, picture turns black, etc)
• problems reported by the program (I haven’t seen this, but “just in case”)

Ok, I will do this
But this random colour pops up when there is no GPU attached,If I use the GPU then random colour doesn’t pop up instead the screen gets freeze and the same things like no power to keyboard and mouse,

You’re using on-board graphics? Sounds like the motherboard could be bad.

Yes, but if I use GPU then screen freezes instead of showing random colour, Any method to make sure that the Motherboard is the culprit??

[jmarket]

If the screen freezes when the GPU is in and reboots when it’s out, you have your proof I’m afraid.

I assume all drivers are updated correct? Have you tried using DDU to uninstall the drivers doing a fresh install of the most up-to-date ones to rule out a bad driver?
