Wife and I just got back yesterday from running the I-95 gauntlet back to Florida..(ugh!)..
anyway before we left, I shut off my desk top, HP, maybe 8-10 years old, windows 10. Unplugged it and unplugged the Ethernet cable...(always do this)..
9 days later it won't boot...giving me a DOS screen saying the CPU cooling fan not detected/operating....looked and could see it was not functioning...shut it off and tried again...nothing.....
Today, same thing...now I get a blank screen, and the cooling fan for the power supply is running but louder than normal..
been thinking about a new computer for some time....maybe that time has come.....
any thoughts?

Were all your clocks flashing?
Ahh, nevermind. I see you said you unplugged it. Covid brain here.

I'd go with the power supply too.

You might have some luck with RESEATING any cards. Some times in the heating and cooling they back out and/or corrode some.
Use an eraser on the card maybe
I've seen that cause pcs to not boot.

I agree. Even reseat connectors. Instead of an eraser, I recommend plain white paper. Erasers leave a film. |

could be.......the fan itself had been acting a bit flaky.....it didnt seem like it was running at top speed for the last year or so...but the weird thing about it, was everything worked fine when I left...9 days of being off...and it breaks.....
sometimes I just don't understand electronic devices....

oh and thanks all for the suggestions...I will fiddle with it again tomorrow....its hard to get PC help in this town, especially if you want them to come to your house.....
I found a "renewed" one on Amazon...exact same model as mine for 167 bucks.... Might buy it and keep mine for parts.....Ive got most of the stuff backed up on external drives...

You can buy replacement power supplies on Amazon and Fleabay for about $30. If you're adventurous like me and can operate a soldering stick, crack open the power supply and look for leaking electrolytic caps. They're axial type, and look like little vertical water towers. If the end on any cap is domed or leaking, desolder it from the PCB, read the specs off the side, and order new ones. The stuff oozing out is not poisonous. The filter caps in these power supplies last about 10 years if you're lucky. When they go bad, the specs drift and the power (various voltages) from the power supply to the parts of the computer becomes unstable. The processors don't like that and they refuse to operate. I fixed a Dell desktop this way a few months back for less than $10 and about an hour of my time. Here's some pics of the patient.  |

I can vouch for the repair that Peegoo noted above, mainly because I repaired a PC years (I mean years!) ago by doing what he recommends. I think it was an Acer PC, but I couldn't say for sure because it was soooo long ago. The new caps did work and I recall being surprised when the PC started working correctly again.

there was a period where the cap manufacturers really screwed up and all the computer companies were having problems. there were ebay sellers selling pre-bagged packages of cans for machines. tell them what you had and they'd send you the replacements. i never saw any as BAD as pictured above, usually just a bulging top.

Honestly, I'd suggest just buying a new PC. Depending on what you are doing with that PC, you can get away with one driven by a faster CPU and SSD for around $500. As far as troubleshooting, power supply is a likely suspect (always the first thing to replace). I wouldn't mess with servicing it, just buy a new one for cheap, but make sure you match the wattage of the old one.

Any FAN related error in my job always means a service call to either replace the fan unit or the system board depending on the system/layout. So getting a duplicate system and swapping the hard drive over is probably the cheapest way to go (as long as you have the tech skillz to do that!).
