This is my first time on this forum so if I seem rude or stupid i'm sorry.
Let me tell you a story: I bought a second handed pc (yes the risks ) for 280€ and it featured: i5 3470, 8gb GEIL ddr3 1066Mhz ram, asrock h61m, gt420, corsair vs450 psu, 750gb 7200rpm hdd.
It was all built in an medion case wich he took al the parts out and put the listed above back in.
So i wanted to use it for gaming and put an msi gtx 750ti 2gb oc in.
So it ran fine for 3+ months. Then i force-closed it (hold the power button in) because it didnt want to shut down, the next day i booted it up everything ran fine but windows said my hard drive needed an check so it did and rebooted, it asked again but this time when it rebooted windows crashed.
I installed an new copy of windows 10 and the drivers with it.
Everything looked to be fine until i booted up gta V and it crashed after 15 minutes, displaying nvidia driver stopped working and has recovered, i found a 'fix' online but it still didnt work.
The next day i took the side panel off and it ran fine for 45 minutes and then it crashed again.
So I took msi afterburner and furmark to check the temps, it was on 58℃ and crashed.
So i thought it couldnt be the gpu temps.
So i dont know what it is, the psu, cpu, ram maybe even the motherboard.
Any suggestions/fixes would make me very happy!
I wish you an nice day.
I have checked the voltages on my PSU, i let furmark run until it displayed nvidia driver has stopped and has recovered. It also states the temps on my gpu.
