First off, i know there are other posts to do with a pc crashing, but ive tried literally everything i could find and i feel as though my case is different. I initially thought it was a psu issue, so i bought an evga 750w psu. This psu faces the grills on the bottom of the case for adequate airflow intake. I also replaced my hard drive with an ssd as i thought i had a faulty segment. I performed a fresh installation of windows and used driver easy to check and manually install all of the latest drivers. I also used geforce experience to update gpu graphics card. Also, the windows monitoring apps simply tell me that the shutdown was unexpected. There were no prior events that may have led to this. I am going to be replacing my gpu soon, because i need an upgrade anyways, but ive tried just about everything i could and no online help has worked for me. Also, sometimes when i boot my pc, it says overclocking failed despite me never having overclocked my pc, and when i enter bios and make no changes at all, it magically works again. To clarify, when i crash my monitor screen remains frozen and the pc is completely unresponsive, but doesnt turn off. I dont get any BSOD. The lights on the keyboard also turn off.
My specs:
intel core i7
Nvidea gefore gtx 960 (switching to rtx 2060 when i save enough money)
Asus z170-p motherboard
evga 750w gold plus psu
Literally any help would be appreciated because ive tried almost everything else and i dont have unlimited money to keep buying new parts.
thanks.
