[NAME]  - If you're using a power strip, surge protector, or UPS, remove those and connect PC directly to a working wall outlet. See if it boots properly now. When the PC starts booting, immediately start tapping F12 to open the boot menu. Look on that menu for the option to run Diagnostics and run all of them, including RAM and extended HDD tests. Copy error messages, if any. And it's possible the power button is the problem, and sleep crashing is an unrelated issue that's just misleading you. You can find the power button module for <$10 so you might want to start there. The Inspiron 3847 Service Manual has instructions to replace the button module.
Hello allMerry christmas I am having some problems with my 6 year old dell inspiron 3847 When i click on the power button, the pc rarely turns.I usually have to click the power button 1000 times for the pc to boot. I am not getting a beep code. At first i thought it was a power button problem, but the pc crashes on sleep, so it is probably not. my specs are i5-4590 rx 480 2x8 corsair 1333mhz ram Corsair GS700 700w psu i have tried -turning on without the gpu -reseating the gpu and cpu -replacing cmos battery -changing the power supply  -tried 1 ram stick at a time But i am still having the same problem please could someone help my figure out what is faulty with my pc thank you in advance have a nice day
