When the Dell logo appears, press F12 key to enter One-time Boot Menu.Running Dell Pre-boot System Assessment or enhanced Preboot System Assessment (Dell PSA or ePSA) To learn more about Dell ePSA or PSA diagnostics, browse to the Dell knowledge base article Resolve Hardware Issues with Built-in and Online Diagnostics (ePSA or PSA Error Codes). Dell SupportAssist or ePSA hardware diagnostic test help check if the hardware devices are working correctly. Dell offers both integrated and online diagnostics. To determine if your Dell computer is experiencing a hardware problem, it is recommended that you first run a hardware diagnostic test on your computer. Running a hardware diagnostic test can help you identify hardware-related problems and provide you troubleshooting steps to help resolve the issue. Laptop computers may also have more than one fan and may vary between different models.Desktop computers have more than one fan - processor (CPU), dedicated or discreet video card (GPU), power supply (PSU), and one or more chassis (case) fans.Your Dell computer may contain several fans to keep the internal components cool: Lint and dust accumulation prevents air from flowing around the cooling fins and causes the fan to work harder. It is important to keep dust from accumulating in your computer and ensure adequate ventilation to help reduce heat. If you notice the computer fan running constantly and making an abnormal or loud noise, this might indicate that the computer is not running as efficiently as possible, and/or clogged air vents. Excessive heat can also cause a significant decrease in performance as most processors automatically reduce the speed of the processor to help compensate for heat-related problems. Its still going WELL beyond the deep memory tests are done.Blocked air vents can cause serious performance issues by restricting airflow, this can cause the processor, system memory (RAM), and other hardware to overheat which may lead to a potential hardware failure. Everything else passes quickly, the SSD drive passes quickly, but this hard drive just takes forever to pass. It passes, but it just takes unnaturally forever. I did notice, however, that one of my hard drives - the one my OS is on and the one i boot from, a 600GB non ssd hard drive - takes forever to go through diagnostics. The highest the CPU temp got in diagnostics is 77c I've run many antiviruses, including ComboFix, and i get nothing. That seems too high to be an average temp just having a browswer open and playing a game. I was even playing an internet game last night for a few hours - nothing too intensive - and the fan eventually had to constantly stay on and the temp averaged about 65C. I just don't think the actions I'm taking warrent such high CPU temps. Occasionally it'll shoot up even higher - into the 80s, and of course the fan blasts and cools everything down, and then it levels off. But I just opened up in a new 8th tab, and the temp shot up to 67C, and then came back down to 46C. and I have 7 other tabs opened and pinned. Having my brower open and nothing else, I'm at 46C. However, I'm getting these temp raises based on non intensive actions i'm taking, like opening a new website in a new tab. I'm used to CPU temp raises and fans running on full blast on intensive programs. Which would be understandable if I was doing CPU-intensive work. The issue I've been recently having is that I am getting CPU temp increases in bursts with accompanying fan bursts to cool it down. I have a Dell m4700 laptop, and its been working great. Apologies upfront for the newbie description of my issue.
