350w switching power suply

My computer is just shutting down with no warning. I took off sides to make sure all 3 fans are working and they are. I am thinking that the power supply might be bad. The unit is not getting hot. Any ideas.

My computer shut off out of nowhere with no warning.


They are a problem when they overheat. No warning just off. Try cleaning the fan and radiator. You will have a fighting chance then.

Shuts off for no apparent reason. Running Windows XP Service Pack 3, AMD Athalon 64 processor with 1GB RAM


If it shuts off randomly it could be to things it could be power suply or virus. i would first off make sure that there is no viruses. make sure u run a virus scan and there is no viruses. if it turns up none i would look into a power suply. if it still shuts off i would look into making sure the heat sink on your cpu is seated correctly and has good heat sink and fan as it could be over heating

I have a model 5BS520C. The light works but when I pull the chain for the fan, I hear the sound of three speeds but the blades do not turn. ed.pfohl@gmail.com


Here some toubleshooting:

Problem 1. Fan will not start.
Probable Cause
1. Fuse or circuit breaker blown.
2. Loose power line connections to the fan, or loose wire connections in the switch housing.
3. Reversing switch in neutral position.

Suggested Remedy
1. Check main and branch circuit fuses or circuit breakers.
2. Check line wire connections to fan and switch wire connections in the switch housing.
3. Make sure reversing switch position is all the way to one side.

WARNING: Make sure main power is turned off.

Problem 2. Fan sounds noisy.
Probable Cause
1. Blades not attached to fan.
2. Loose screws in motor housing.
3. Screws securing fan blade flanges to motor hub are loose.
4. Switch housing binding against the blade hub.
5. Wire connectors inside switch housing rattling.
6. Screws holding blades to flanges are loose.

Suggested Remedy
1. Attach blades to fan before operating.
2. Check to make sure all screws in motor housing are snug (not over-tight).
3. Check to make sure the screws which attach the fan flanges to the motor hub are tight.
4. Check to make sure that the switch housing does not bind against the blade hub.
5. Check to make sure wire connectors in switch housing are not rattling against each other or against the interior wall of the witch housing.
6. Tighten screws securely.

WARNING: Make sure main power is turned off.

Problem 3. Fan wobbles
Probable Cause
1. Setscrew in motor coupling is loose.
2. Setscrew in the hanger ball/downrod assembly is loose.
3. Screws securing fan blade flanges to motor hub are loose.
4. Fan blade flanges not seated properly.
5. Hanger bracket and/or outlet box is not securely fastened.
6. Fan blades could be out of balance.

Suggested Remedy
1. Tighten the setscrew in the motor coupling.
2. Tighten the setscrew in the hanger ball/downrod assembly.
3. Check to be sure screws which attach the fan blade to motor hub are tight.
4. Check to be sure the fan blade flanges seat firmly and uniformly to the surface of the motor hub. If flanges are seated incorrectly, loosen the flange screws and retighten.
5. Tighten the hanger bracket screws to the outlet box, and/or secure outlet box.
6. Interchanging an adjacent (side-by-side) blade pair can redistribute the weight and result in smoother operation.

WARNING: FOR YOUR OWN SAFETY TURN OFF POWER AT FUSE BOX OR CIRCUIT BREAKER BEFORE TROUBLESHOOTING YOUR FAN!!!

Hope helps.

I took my gateway gt5620 in because it would shut down by itself. It would restart. They took the graphics card out and it worked for a while. Now it is doing the shut down again. I took the side panel off...


Sounds like an overheating problem. May want to remove the processor and check the heat sink material. While you have it out you can clean the fan and the heat sink. Make sure your air flow isnt blocked in any way and neaten up the cables if necessary. You could also consider adding another fan.

My DR-B300ATX power supply is failing.


STOP...
Dont try to repair your Power suply unless you know what your doing. They can hold enough charge in its capacitors to electrocute you.

Just remove it from P.C. take it to a computer store and say: Eh hem, I need one of these to replace this one.

Make sure its got at least the same amount if not more connectors as the original, make sure its also the right type I.E. ATX POWER SUPPLY, and I would recomend getting one a little stronger than the one you blew out, something like a 350w

Probably get one for under $80.

replace and enjoy.

My Philips Freevents sometimes wont turn on and when it does it shuts down without me shutting it down


If the computer shuts down with no warning then it could be your power supply is faulty, which explains it not turning on sometimes. Just check the back of the PC to make sure it is plugged in properly (TURN OFF ALL POWER TO THE PC BEFORE CHECKING). if this does not help, get it looked at by your local qualified computer technician if you don't know how to replace a power supply. Also, a connection to the motherboard to the Power button may have a fault somewhere, which also means take it in for a look if you don't know what to do. If it does give you warning with 'Windows is shutting down' it can be the following things.
1- Your power button on the PC is sticky and movement causes the computer to think you have pressed it and so it shuts down, which can also explain why it wont turn on all the time. Just use some household grease cutter and spray it on the outside of the button, turn off the power supply to th computer and press it in and out a few times to get it back to working order
2- A Virus is shutting your computer down on you, but this does not fully explain why it won't turn on but this could be an effect of the virus so use a virus checker to see if this is the case
3- Your computer system is getting too hot and usually a computer has setting which shuts it down before permanent damage happens. Check your PC fans to make sure they are running and feel around where your computer sits to see if its warm or hot and replace the fans or put your PC in a cooler environment

Hope This helps

Pc switches off


something could be overheating. does the video card have a fan? is it working? when is the last time you blew dust out of the cpu fins and internal fans?

The fan alert warning when you start up the computer says "WARNING CPU FAN FAILURE SHUTTING DOWN cPU TO AVOID DAMAGE" AND THEN IT SHUTS OFF.


I am going to assume (and we all know what assume means) - that you have a desktop. With the power disconnected, take the side of your computer off. Take a can of air (you can get them anywhere) and blow out your fans (all of them) dust and dirt can cause the fan to stop working, dirt and dust can even short out your computer. I don't suggest using a vacume cleaner - for the parts (on a vacume cleaner) are so large you can bump a circuit or diode that can break off.

Once you have air cleaned the fans, while the side is still off, power up your computer and see if any of your fans are not working, if one is not - that is what needs to be replaced.
