Question about HP Compaq Presario SR2150NX PC Desktop

1 Answer

Desktop computer fan runs constantly

My Compaq SR1420NX desktop computer fan runs constantly. It begins within a minute or two following start-up. It is constant whirring loud noise. I believe it should not do so. I'm wondering if it could be due to something undesirable running in processor all the time. I once removed (long time ago) a previously used antivirus (AntiVir) program by deleting the program files instead of by using the proper Windows uninstaller. Now I use Norton, but I still occasionally see a right click menu item to check object with old AntiVir which cannot be started. It's only my guess that that may have something to do with the continuous loud fan noise which sometimes sounds like a low level vacuum cleaner noise. Otherwise my computer runs but slow at times. I'd like to stop that darn fan from running constantly! Any suggestions appreciated. Thank you.

Hi,

Desktop fans do run constantly, you cannot avoid this.

The reason they get loud is because there will be a build up of dust on the fan blades.

To rectify this problem turn off the computer and remove the power cord from the rear. Then you need to remove the side panel from the base unit to expose the motherboard.

You will see that inside the case it is full of dust. Look at the CPU fan (the fan on the motherboard) also take notice of any case fans too, they are at the back.

To clean the fans and the case you can use a clean dry paintbrush or compressed air.

Once the inside of the case is cleaned you will see a noticeable drop in noise.


Regards.

Computer Power comes on, shows compaq first screen, then everything stops. press esc, F10 or F12 and nothing happens. just continues to show the compaq screen. Any suggestions?


Try unplugging everything you can from the computer. Only leave keyboard, monitor, and power cables connected. Then try to turn on again. If computer boots now, then start adding peripherals back one at a time, rebooting each time. when you get the hang, there is your suspect peripheral.

Also, is the monitor itself having issues, or is it the computer? Look at the power light on the monitor, is it staying green, or is turning back to same color when it is in standby state?

Yellow power light on HP SR1420NX


For reasons yet to be determined, your computer is not talking to your monitor.

This could be the monitor cable came loose from the tower (this is our favorite, because it is such an easy repair), or something on the motherboard (that is, anything) that is not functioning and preventing your computer from starting.

Unplug the connecting cable, and plug it back in again, making sure that it is seated properly.

Do you hear any sounds besides the fans? You should be able to hear the faint clicking of a hard drive starting up also. If you hear this, the problem is not in the computer, but in the communication to the monitor.

Good luck
