Windows keeps starting up and restarting.

I just put a gtx 750 and an antec earthwatts green psu into an ol computer with a q6600, It runs windows 10. When I try to boot it up it gets to the windows logo and the loading circle and then the monitor says "no signal" and then turns back on again to the bios logo.

Does anyone know what the problem could be???

It could be a bad driver. Boot to safe mode with networking, and download this:

Use it to completely uninstall your old display drivers. After this, download and install the latest Windows 10-compatible drivers for your graphics card here:
