PC stuck in reboot loop after cleaning

[depakjan]

As the title says PC keeps restarting within 5 mins in random screens, Even in BIOS !!!, I have tried many things ,

1. Removed all RAM module, kept only in all 4 slots 1 by 1, the same problem exisits
2. Removed and re plugged all components
3. Removed CPU and re installed, same problem
4. Read about power switch causing shorts, so unplugged all of them, jaudio, just, JFP1 and started the pc using screw driver, still the same problem !!!

At this point I don’t know what to do, I don’t have any spare CPU or MB or PSU or GPU

What else can I try, even if I have buy something I am not sure which one should I buy , how can I go about this

Sounds like the system is overheating.

Could also be the PSU is failing.

1. Removed CPU and re installed, same problem

Should of remove the old thermal paste and applied new.

Never do this unless you have thermal paste t apply.

Sorry but you have post on a tech forum asking for help but have provided zero information about your computer or it`s hardware, this makes it impossible for anyone to even hazard a guess as to what is going on.

Is the computer a custom build or brand name such as Dell or HP, if a brand name provide the model name or series number (not serial) if a custom build post the brand and model name or number for the following:

OS
CPU
Motherboard
RAM (including the amount and Number of Sticks)
Add on Video Card if one is used.
Power Supply Unit

Providing these details will enable folk to better help you.
