I recently received my graphics card after asus completed an rma. It worked great for a few days but now my system is working horribly. My computer had been consistently crashing for weeks even after replacing a power supply which I thought could help. Before sending it to asus I tested my ram modules, power supply, reinstalled drivers nearly 10 times (I tried every driver version available), reinstalled Windows 4 times, and more. My computer was working fine but last night I decided to try using asus’s oc profile for my processor and setting my ram to its speed of 3200. My computer began crashing. I went back into the bios and reset the settings. It worked fine for a few hours and I went to bed. Today I booted it up and experienced crashing immediately while gaming. Now the pc is stuck in an infinite loop of automatic repair and failed to load. My cpu is an i7-7700k my motherboard is a asus strip z270e my graphics card is a asus strix 1080ti my power supply is a new Corsair 750 watt (I forgot which version but it’s 80 plus gold rated) I have 2x8 gigs of trident z at 3200 mhz and an ssd that’s about 4 years old and a hardrive that’s about 2. Should I reinstall Windows? Is there any more suggestions my bios settings are default now
