Check your memory sticks to make sure that they are full inserted and did not come loose. Check the power from power supply going to HD. Make sure it is getting power. You can also remove your motherboard and test components with an ohmmeter to see if there are any burned out components which is very possible. Have seen bad boards and bad power supply's both cause your problem

I have a Compaq Presario PC, SR5210NX Processor with Intel Celeron Processor 420. I got a message that windows did not start correctly and it said to run the diagnostic, which I did. After that was done,...


Unplug power and Open the computer case. Vacuum all the dust
inside it. Visually inspect all the fans: Power Supply, CPU, Chipset
and Case...Make sure they are spinning easily and freely.
Plug the power in, and turn on your system. Watch the fans, especially
the CPU Fan and the Main Board Fan (System Fan). Oil and dust over
times may accumulate and prevent the fans from spinning properly.
If you are handy, you can remove them, give them a good wash and lubricate
the shafts with a few drops of WD-40, they will be as good as new again.
Fans don't go bad that easily.

The controller will not turn on. Green light on back comes on but when we turn on the unit, the fan starts briefly and then the power cuts off.


Bad Power Supply. Weak Voltage power rail.

Not enough power to turn the Processor on, and keep it on.

1) ALL those LED lights together, use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts

3) A typical Processor can use 51 to 125 Watts. Depends on what Processor it is. (Older Processors use less Wattage)

The Compaq Presario SR1810NX desktop computer, comes with an AMD Sempron 3200+, processor.

(Uses the Socket 939 processor socket)

[Maximum operating capability is a 1.8GigaHertz frequency rate.
1.8GHz

Giga = Approximately 1 Billion
Hertz stands for Cycles per Second.
Frequency Rate is correct computer speak for 'Speed'
The AMD Sempron 3200+ processor, can operate at a maximum frequency rate of 1.8 Billion Cycles per Second ]

The AMD Sempron 3200+, can use up to 62 Watts,

When you press the plastic Power On button, you are contacting a Power On switch inside it.
(Typical ATX Power On switch,

http://www.directron.com/atxswitch.html )

When an ATX power supply is plugged into power, there is a 5 Volt Standby power, present inside the power supply.

Pressing the momentary contact power on switch, closes a circuit that directs the 5 Volt Standby power to 'excite' the power supply, and turn it on.

The first chip to receive power is the BIOS chip.
[Chip and Chipset are slang terms for I.C.
Integrated Circuit.
BIOS stands for Basic Input/Output System]

BIOS,

http://en.wikipedia.org/wiki/BIOS ]

BIOS looks to see what devices are installed, does a Ram Memory count, TURNS the Processor on, and hands the computer over to the Operating System.
(Windows XP is one example of an O/S. Operating System)

The LED lights receive power, so do the fans, and the Harddrive. When it's time for the Processor to kick on, there isn't enough power, and the Power Supply 'falls to it's knees'.

Replace the Power Supply.
It's just one of the basic ATX power supply's that are readily available in a multitude of places.
The Wattage is 300 Watts.

The ATX form factor for this power supply, (Size and shape), is approximately 6 inches Long, 6 inches Wide, and 3-1/2 inches Tall.

Compaq presario doesnt boot upon powering up


boot into the bios or if bios support diagnostics boot into that (typically F1 of F10 on power up) If that is not an option boot off the CD recovery disk and run diagnostics on the HD. Let me know we can take it from there.

I recently had a new power supply installed in my compaq presario SR1318NX, now the fans run almost constantly. The air from the fans does not feel hot, nor does the tower. Is this serious?


Hi,

In a desktop computer the fan is supposed to run constantly otherwise the processor would get that hot the system would repeatedly shut down or even damage the processor or motherboard.

If the fan is noisy then chances are that the fan blades need cleaning of dust.

Other than that you have nothing to worry about.


Regards.

You probably put more than a pin-head size drop of heat grease compound on CPU, thus "bleeding" over on the CPU, effectively overheating processor (very common). In any event, your problem is overheating -that's *the* place to look for now.
