Question about Computers & Internet
From one moment to another the desktop computer does not boot, shows no display, fans running on high speed and harddisk light is on. (also the cd and dvd units are running for a short time).
Try blowing the dust out of the inside, around the vents, around the fans and by the cpu and heat sink.
Also remove the fan as it sits on the cpu and heat sink. Then remove the heat sink that sits on the cpu, then remove the cpu by releasing the latch on the side of the bay it sits in (remember how the cpu goes back into the bay). Now clean off the old dried up thermal paste on top of the cpu and on the heat sink that sits on the cpu. Put the cpu back into the bay and secure the latch. Apply a fresh coat of Thermal Paste to the CPU and Heat Sink. Put everything back together then reboot.
If the thermal paste has dried or is too thin to keep the unit cool it's like metal touching metal and shorts out the system so it can't boot.

Change the setting in the BIOS menu. reboot your computer.. when you see the dell logo.. press F1 (or F2 if F1 doesn't work) button until you see the BIOS screen. Check for fan options and change it
