Question about PC Desktops
I have a compaq s3310cl, when u turn it on it makes a buzzing sound which doesn't stop and nothing will down load to start up page. and the monitor is a black screen, but monitor works.
A) Look at the back of the computer at the Power Supply fan, and tell me if it's spinning. (Where the power cord plugs in, is the Power Supply)
B) Open the computer case, look at the Processor fan, and tell me if it is spinning.
Also is the computer dirty inside, as well as inside the Power Supply?
DO NOT touch anything inside the computer until it is unplugged from power, and you have followed Anti-Static precautions.
From there I would diagnose the Power Supply. The Compaq Presario s3310cl desktop computer, came with a generic wimpy 200 Watt power supply.
HP Support > Compaq Presario s3310cl desktop computer > Specifications,
Back when the Power Supply was made power supply manufacturers were 'fudging' the actual maximum Wattage rating.
True Wattage rating is more like 60 percent of what is stated.
My belief at this point of the diagnoses due to your brief statement, is that the computer is dirty inside, and the Power Supply has gone to the great power supply graveyard.
(Bad Power Supply)
Even if the Power On LED is lit, fans are spinning, and the Power Supply fan is running, you may have a bad Power Supply.
Weak Voltage power rail.
1) ALL the LED lights 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.
(General statement. Older CPU's use less power)
The Compaq Presario s3310cl uses an Intel Pentium 4, that fits in a Socket 478 processor socket, and at maximum capability, operates at a 2.53GigaHertz frequency rate.
When operating at the maximum frequency rate it can use up to 61.5 Watts.
(sSpec Number - SL6D8)
2) Socket 478 processor socket,
(In the HP Support Product Specifications, it's listed to the right of the heading - Processor Architecture.
No Processor running, No computer.
No computer operating = No Signal on the monitor, or a black monitor screen.
The SMPS in your computer (Switched Mode Power Supply) has two cooling components.
1) The Fan
2) Heatsink's used inside.
Typical construction of a Heatsink, is a plate of metal with tall, thin fins protruding from it.
The plate of metal absorbs heat from whatever object it is placed against.
The tall, thin fins then absorb the heat from the plate of metal, whereby the fins radiate the heat away.
If a fan is used in conjunction with a Heatsink, (Such as a Power Supply, or Processor for example), the air flow from the fan helps to carry heat away from the fins.
Heat = Wasted Energy
The more heat developed inside the Power Supply, the more the Power Supply strains to keep up with the call for power.
Eventually components inside the Power Supply fail, and the Power Supply itself fails.
Doesn't take very much 'Gunk' on the fan, and Heatsink's inside the Power Supply, to make the cooling capacity of these two cooling components, drop tremendously.
Basic typical construction of an SMPS, is shown to the upper right of the page in a photo.
You can left-click on the photo to enlarge. You can enlarge twice.
This is NOT, I repeat NOT, an advertisement to open the Power Supply!
If there are any Electrolytic Capacitors that are still good in that Power Supply, they can release their charge to you!
Electrolytic Capacitors are designed to slowly build up a charge, then release it all at once.
You can compare them, to a large swimming pool being filled up slowly by a garden hose, then one wall of the pool is taken down all at once.
Once power is removed from an Electrolytic Capacitor, (Such as unplugging a Power Supply from power), they can hold a charge for weeks, months, or sometimes over a year.
If your finger/s, touch the terminals on the bottom of a Radial Aluminum Electrolytic Capacitor, the charge could be released to you!
If your finger/s, touch a circuit that one, or more Radial Aluminum Electrolytic Capacitors are in, the charge could be released to you!
The shock can range from Bad to FATAL.
Your body carries Static electricity.
Static WILL fry out (Short Circuit) the hardware components inside a computer.
Work on a table. Computer unplugged from power, computer case open.
TOUCH the metal frame of the open computer case to relieve your body of Static, BEFORE you reach inside. (Not shouting)
If you get up in the middle of working on your computer, and walk away, upon your return be Sure to touch the metal frame again ]
