PC refused to run inside

I was facing sudden blank screen issues with my system then after some days a total display failure occurred keep in mind that all of the voltages and temperatures were in normal range , so in order to troubleshoot this problem I have pulled out entire components from the case then after applying some home remedies it has been able to show display without being fitted in the case so after putting it back into the case unexpectedly it showed no display :o

This situation does not make any sense to me that how its running fine outside the case now for 2 hours without a single glitch !!!!

Do you have a dedicated graphics card or is it on board VGA ?

check the VGA cable and if possible replace it with a new one.

You should check the case is it touching the motherboard from the bottom side or any loose connection or any earthing problem cause these no display situations.

Yes but it does not make any difference while running on on-board vga
