Brand new computer won't stop crashing.

Hi, I can't get my computer to stop resetting itself intermittently. This is a new computer I built myself. Whenever I browse the internet for more than a few minutes my screen goes black without a BSOD and the computer starts booting. It gives the windows didn't shut down correctly safe mode prompt. The crashes can happen anytime but are only consistent while browsing the internet. I've tried re installing windows and the event viewer tells me nothing. I've also tried monitoring my temps but nothing is going very high at all. The crashes are no more common under heavy load and I removed my GPU to see if the PSU was failing. Here are my specifications. Any help would be immensely appreciated.

  1. What power supply?
  2. Sorry I didn't get back sooner.

  3. Best answer
    My answer might be completely wrong.

    The PSU seems good. The CPU/heatsink came with thermal paste pre-applied right?

    It is probably general overheating. I only buy prebuilts (not custom builds) and pop in a new GPU and PSU nowadays since I couldn't calculate the volume and direction of airflow needed for the towers available for purchase.

    What case are you using and how are the fans installed?

    Post a picture of your case and/or describe the direction of the air flow. I have never built a system myself though. I am just referencing the issues that I had with a custom built that I bought way way back.

    In general, you want to have case vents (front panel, side panel, etc) letting air in and have all the fans pulling air out of the case.
  4. I am confident that it is not an overheat issue. I've been monitoring temps as that was my first guess. My computer crashes the most when browsing the internet. I've re installed windows and used a few different browsers. Yes the paste was preapplied. My computer does not crash under heavy load while playing modded skyrim or during stress tests. Even during stress tests nothing went above 65c.
