    If that is the case I am afraid to say that your PC is seriously infected with virus. Use a bootable CD to boot it, if you have. Take the back up of all important data and Re-install the operating system. I don't see any other possibility.

Computer idles high then shuts down


When you say "idles high" do you mean you hear fans spinning faster or louder? If so, a fan spinning at higher than normal speeds is indicative of components/chips being run aggressively causing them to run at much higher temperatures. You may want to look into getting temperature monitoring software like CPU-Z to monitor the temperatures of your CPU and GPU. These components are the most common ones to be running at high temperatures. If any fan has failed on them the secondary fans (if there is one) will run at much higher speeds to compensate. Your PC may have a safety precaution to automatically shut down if certain temperatures are reached to prevent permanent damage to the components. Are you getting any blue screens before it shuts down?

Red hard drive light and fan continuously running


Let's diagnose from your statements;

A) No display on monitor

B) Harddrive activity LED is on

C) Fan keeps running. Assume your reference is to the computer case fan. IMHO if it was a reference to the Processor fan, you would have stated so.

D) Power Supply changed. Assumption is that it is KNOWN to be good......

A1) Following a diagnostic flowchart, you would rule out the possibilities of a problem, one by one, and step by step.

No display on the monitor can mean a lot of things, however with the additional information we can narrow it down further....

B1) The Harddrive activity LED is on. The way you made the statement, makes me think you are referring to it is CONSTANTLY on.

Reason?
Harddrive is in an endless loop. BIOS is trying to find the Boot record on the Harddrive.
However for some reason it isn't finding it.

C1) Fan keeps running....
This leads me more to believe the reference is now, to the Processor Fan.
Processor fan running at high speed.

D1) When someone states they 'Changed' the Power Supply, instead of Replaced the Power Supply, this leads me to believe the reference is to another Power Supply that was laying around, and not a new Power Supply.

Therefore makes me want to ask;
"How do you know the Power Supply is indeed good?
All 3 main voltage power rails are good?
3.3 Volt, 5 Volt, and 12 Volt? (DC)"

A Power Supply with a weak voltage power rail, will show the symptoms you are seeing.
Why?

1) If ALL of the LED's (Light Emitting Diode) were on at once, they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use 51 to 130 Watts of power.
Just depends on what Processor it is.

No Processor running, no 'Brain'
No 'Brain' running, no computer.

You press the Power On button. This plastic assembly then presses against a Power On switch, located inside it.

The Soft Power On circuit is activated. This 'excites' the Power Supply, and turns it on.
The first chipset to receive power is the BIOS chipset.
The Basic Input/Output System program is initialized.

BIOS looks to see what devices are connected, does a Ram Memory count, TURNS THE PROCESSOR ON, and hands the computer over to the Operating System.
(In this case the O/S is some version of Windows)

Processor is NOT turning on. No 'brain' operating to find the Boot record on the Harddrive.
Harddrive spins in an endless loop.

Power Supply is KNOWN to be good? Came out of a working computer?
Power Supply is a new one?
Still doesn't mean it is good. Test the 3 main voltage power rails, with a multimeter.

Assuming the Power Supply IS indeed good......

Clean out the inside of the computer.
Replace the Thermal Paste on the Processor (CPU)
Make SURE you are following Anti-Static Procedures.
[The CPU (Processor) is the MOST susceptible hardware component to Static shock ]

However, after replacing the Thermal Paste, do not plug the Power Supply into power.

Press the Power On button in, and hold in for a count of 10 seconds.
Let go.
Do this procedure 2 more times.
What you are doing is clearing CMOS Error Codes, and resetting BIOS Setup back to the factory default settings.
The former matters, not the latter. Just telling you the 'whole story'.

NOW plug the Power Supply into power. WAIT 1 minute, turn the computer on.

Post back in a Comment with the results. Or click on Reply at end of solution, and post results.

Need guidance in replacing the Thermal Paste on the Processor (CPU)?
Post the computer manufacturer name, and model number.
The Model Number can be found on the Back of the computer, or up on the side of the computer tower.

I turn on my tower and the fans move and the disk try clicks like it wants to spin then i turn the monitor on and it turns green them orange right away and says entering power save mode waht do i do


1) Unplug the computer from power.

2) Press the Power On button in, and hold it in for a count of 10 seconds.
(Count)

Let go of the Power On button.
Do this same procedure two more times. (Or until the Power On LED does not light up anymore)

3) Plug the computer into power. WAIT 1 minute, turn the computer on.

The fans should spin at high speed for a few seconds, then settle down.
Let's see if the computer boots.

Post back in a Comment, and we will go from there.

Why does my fan seem to be cycling at all times which is slowing down the computer big time


your fan has nothing to do with your computer slowing down.
your fan goes on when a threshold is reach in the cpu temperature or another component's temperature being cooled. the question is what's is causing your cpu or your chipset to work harder than usual causing your system to seem to be sluggish??

the simple answer is malware and need for a clean up and tune up

I suggest you do the following:

1. get an air can, open the case and without touching anything and watching for ESD, dust off your system free.

2. close the case and turn your computer on

3. update your antivirus and run deep scans

4. get all critical updates for your system from windows update

5. download, spybot search and destroy, malwarebytes, superantispyware, and a square free edition, update them and run deep scans.

6. defrag your hard drive

7. to improve perforamance make sure you update or upgrade memory

good luck!

Loud noise when turning on my computer


THIS IS NORMAL!!!
When the machine boots up the fans are running at full speed, and after a moment the bios loads teh power management that lowers the fans to the needed speeds. If you tax your computer the fans will speed up to compensate for the heat produced and will get louder then as well...
The larger and more powerful your CPU and Video Card the louder the startup will be. Some of the newest quad core computers with high dollar vido cards will sound like a jet taking off when starting up, I know mine does!

Fans run at full speed under normal task.


THE PROBLEM IS THAT THE CPU AND MB AND PSU IS NOT COOLING OFF ENOUGH AND CAUSING THE FAN TO RUN ON HIGH ALL THE TIME, THE PSU MAY NOT HAVE ENOUGH WATTS POWER TO RUN THE CONFIGURATION TO KEEP THE SYSTEM AND HARDWARE TO COOL.

I READ IT IN ONE OF MY PC MAGAZINE, ANOTHER PERSON UPRADED SYSTEM, ADDED SOME OTHER STUFF BUT THE MB AND POWER SUPPLY UNIT DIDNT HAVE ENOUGH WATTS TO SUPPORT BASIC REQUIREMENTS OPERATING THE SYSTEM BASIC NEEDS.
FIND SOFTWARE THAT KEEPS EYE ON HEAT ISSUES, MB, VIDEO CARD, RAM, PS, CPU, CPU COOLERS, NIC CARDS, SOUND CARDS,
ETC.
EACH PART REQUIRES SO MUCH POWER
AND HERE HOW IT BRAKE DOWN FOR EACH COMPONET

MB 20-35+ WATTS
CD ROM 20-25 WATTS
DVD 30-45 WATTS
DISK DRIVE 5 WATTS
HD 5-15 WATTS
STANDARD VIDEO VARD 5-15 WATTS
MEMORY 5 WATTS PER MB

NEW SYSTEMS WITH THE FOLLOWING STUFF IN IT FLOPPY DRIVE,CD-ROM, MB, 16MB RAM, REQUIRES A MIN. 150 WATTS OF POWER.

BUT I KNOW YOU MAY HAVE TOP OF THE LINE VIDEO CARD WITH GGR4 WITH 512MB
MEMORY, 2-8 GIG OF RAM, 23 INCH LCD MONITOR, 2 500GB HD, BLUETOOTH AND WIRELESS NETORK, AND WIFI CAPABILITIES,
NEW DUAL CORE CPU TOP LINE MOTHERBOARD, COOLED VIDEO CARD,RAM COOLER ALSO AND THIS SYSTEM POWER WATTAGE REQUIREMENTS MAYBE SOME WHERE AROUND 400-600 WATT, AND MOST OF THAT IS FOR THE SYSTEM RAM AND THE VIDEO RAM YOU ARE RUNNING
REMEMBER 5 WATTS PER 1 MEGABYTE OF
RAM
IT WILL ADD UP FAST BOY'S AND GAL'S

ROD

PS I HOPE I DIDNT BORE ANYONE,
IT MAY SAVE YOUR SYSTEM FROM BURNING UP.

Same problem... orange power light, fan starts slow and builds up to very high speed.
I removed my video card and SIMMs --> it beeped on boot and the fan did not speed up.
Put one SIMM back in --> booted fine, pressed F2 to view BIOS. Memory reported fine.
Put all SIMMs back in --> all fine now.

Fan in my Dell desktop PC runs at very high speeds from time to time


Check your manual for instructions to see if CPU temperature monitoring is done in that system.
You may be able to view that actual operating temp. of your processor.
If that system is so equipt, then it is very possible that the fan speed is regulated by temperature and it will vary according to ambient and internal temperature to conserve a tiny bit of power.

If nothing else, you can block airflow into or out of the system box to see if the fan speed increases after a few minutes.
Blocking the exhaust in the back of the unit will probably be enough.

NOTE: DON"T walk away if you decide to experiment - you may fry some chips and those don't taste good at all!
