Please help diagnose my pc he's all I've got :(

I'm gonna try to make it short but informative.
Got a prebuilt pc about 3-4 years ago. Have used it heavily.
A few months ago I started noticing I would get no signal on my screen which at the time was an old TV. Let's call it monitor 1.
Turning off the pc and holding down the power button for a long time with power cord disconnected would usually do the trick.
Eventually I got a new screen and ofcourse it did the same thing. I was even using a different port. dp instead of hdmi. It still did the no signal thing from time to time but I lived with it.
Recently I had a Windows auto repair situation. But it kept looping once it reached 6%. I then tried to reinstall Windows and it turned itself off and basically acted the same way it did when It was trying to auto repair. Basically looping.
Eventually I got some advice to disconnect my gpu and use the integrated one. Which I decided to do.
The pc finally started up and installed Windows. Seemed to work fine untill today. No signal again. If any information is missing just ask me, I'm quite active and will usually respond fast.

I guess you don't have any means to try out a different power supply?

Did you upgrade the hardware of your PC at any point? (Btw a complete list of system specs always helps)

The hard drive might also be damaged or there are simply some errors in the file system. Hook up the hard drive to any working system and read out the S.M.A.R.T values, preferably with the tool the drive manufacturer provides on their website (e.g. SeaTools for Seagate drives).
Also, if the OS is Windows, run the command line and type in "chkdsk [insert drive letter here, e.g. "c:"] /f" - without the "". This will take a while and may repair a damaged file system.

Haven't upgraded it. But I have moved stuff around as I've cleaned parts of it, With decent care though. And I do not have the means to try out a different power supply sadly. Could it be the harddrive even though removing the gpu fixed the windows installing thing? I could provide a full list with model numbers or my hardware but I don't have access to it right now. In simple words though its
1 tb hard drive
8 gb ram
Gtx 760 1.5gb(currently not in the system)
I5 quad core.
And 500 watt power supply. Will return with full model numbers in about a couple of hours if necessary.
