Hello everyone,
Bought a custom rig about two years ago and it ran fine until about 3 months ago. It would beep for about 5 minutes on start up, and the beep signal indicated fan problems. However, I went through all my fans, they were all running and spinning fine, no extra noise or anything and had good airflow, so after taking the computer apart twice I attributed to a faulty fan sensor and left it at that. Like I said, it only beeped for a few minutes then it wouldn't beep again, even after hours of use (plus all the fans were still spinning).
Then, two nights ago it started shutting down randomly. After again taking the computer apart to check connections and capacitors (I hadn't added anything since I bought the PC), I realized that I had never cleaned the filter between my push-pull fans, and it was pretty bad.
However, after cleaning, the computer no longer beeps (at all, for anything), and it still shuts of randomly. Sometimes it runs for as long as 10-15 minutes, other times it's less than 30 seconds. I have disassembled the computer from top to bottom twice, checked each component individually, ran through several different startups with no improvement. Even with no RAM loaded or video card installed, the computer won't beep. It does load to Windows fine with everything installed, it just shuts off randomly.
I did download CPUID Hardware Monitor in order to check the CPU temps, and I noticed that even at startup the CPU is running at 100° C. Sometimes it starts at as low as 95°, but after a few seconds it hits 100° and within a minute of that point shuts off. The fans all still spin, it's liquid cooled, but I still can't seem to get the temps down. Tonight I'm going to start by reapplying the thermal paste, after I checked how the heatsink was sitting it looked pretty dry and definitely wasn't sitting flat. Would that fix the motherboard speaker by chance?
I wasn't sure if that could really be the only problem though, so I thought I'd post on here first and maybe someone that had ran into before would know what to do. I'll do a separate post with my specs since this first post ran a bit long...
