Solved I am new to building, this is my first build so don't tear me a new one.

Specs:
Asrock b550m steel legend
Ryzen 3700x
Gigabyte 3070 oc vision
Corsair Vengeance rgb pro SL
Crucial p2 1tb nvme
Corsair rm750x

When i turn the PC on it boot loops once every time without fail, thus prompting the red VGA and Boot LED's to come on although the PC still boots to the windows 10 login page. So That is what i notice first when the PC boots, after i load a game such as rust and play for around 30 mins to an hour it will just completely restart again with the red VGA and BOOT lights showing, i have installed the correct drivers and reseeded The GPU and the nvme but to no avail. I want to believe it is temp related and could easily be fixed but im no technician.
I would appreciate if i could get some tips or see if anyone else is struggling with the same issue.

The psu is a Corsair Rm750x, the recommended psu for 3070 is a 650w but i got 750w to be safe and the temps never reach the maximum temp i set, the highest id say is around 70-80 Celsius, also i will give it a go reassembling outside the case i havent tried that yet.

make and model of PSU?
have you gone into the BIOS and checked the temps?

first up, I would dismantle the rig and reassemble outside the case, say, on a piece of cardboard, on a table or floor.
since this is your first, can;t rule out a short circuit somewhere, over heating, or whatever, and having all the innards readily accessible makes troubleshooting a lot easier if parts have to be continually swapped in and out.

I am having alot of trouble finding the problem, ive reinstalled drivers etc, reseeded every component outside the case, But when i run the heaven benchmark it crashes the pc at around 3 minutes give or take with the temp never reaching over 70 Celsius, The power supply is 750w rmx series from corsair plenty enough juice for the 3070, it is not daisy chained either i use 2 separate cables that came with the psu for GPU power.

Have you made sure that the modular connections are secure at both ends, when checking the ATX connections on the MB be sure not to press down to hard or the MB will flex and damage the electrical circuit, which btw would result in the sort of behaviour that you describe.

RAM
16.0GB Dual-Channel Unknown @ 1796MHz

Your RAM is being clocked past what the CPU is compatible with which is 3200MHz going by the AMD specs here

Disable XMP in the BIOS and then manually set the RAM speed to 3200MHz, save the new setting and then exit the BIOS.

Power Profile
Active power scheme: High performance

Change the Windows Power Plan to Balanced, Ultra and High Performance are a form of overclocking that is known to cause stability and overheating issues and the setting should only be used for gaming type notebooks that have a discrete GPU that needs the extra power.
