https://www.techpowerup.com/gpu-specs/radeon-hd-7570.c393, the video card has a TDP of 60w, maybe the motherboard can't supply that power trough the pci-e slot. Try with a less 'power hungry' video card.

Then, i agree, try with lower voltage, usually 'undervolting' makes things run a little more cooler, and even if Intel states 3.2v-3.45v, it may run happy at just 3v because silicon dies are not identical (that's why you have a range of voltages). If you don't have extra pads, you can get the …

If it's outputting ~3.5v it should be the adjustable voltage regulator(the lower one in the schematic, 3.45v out) and you should be able to change the output voltage by changing the values of R1 and R2 using the formula.

You can put the diode back(the one you removed) and just ad a schottky diode with a low v fdrop (~0.2v) between the + battery and + from the motherboard to keep the current flowing only in one direction and test after that. This way no matter if the circuit was designed with charging in mind, …
