No power except fan

I have no power at all except the fan. I replaced the power supply and it worked at the time. The next day it has the same problem. I tried resetting all the connections and disconnecting everything except the monitor with no luck.

It's your CPU. It sounds like you didn't apply the thermal liquid between your CPU and fan.

Computer won't turn on.


There must be a problem with your power switch on your computer casing, or motherboard or power supply.

Detach your power supply and try this, to check if your power supply really works. If the auxiliary fan will turn, your power supply is good

25627818-lfqggqo5gl3n2v4xynrvsb5u-5-2.jpg If the cpu cooling fan and power supply did not turn the fan, but you have checked already the power supply that is working then you can conclude that your motherboard is need to be replace. But the power supply and motherboard and working, meaning to say your computer casing need to be replace or try fixing the contact of the switches attach to your casing.

Have a good day.

Hp Pavilion a1620n seems completely dead. Went through a diagnostic and presumed the ps was burnt out. Have since seen the ps light on while all internal cables are unplugged. Can plug all cables in and ps...


No, it indicates a bad power supply.

1) ALL the lights use less than 1 Watt
2) EACH fan uses 2 to 3 Watts

3) A typical processor uses 55 to 125 WATTS.

The base model of the HP Pavilion a1620n Desktop PC, comes with an Intel Pentium D 925
(Operates at a maximum of 3.0GHz)

The Intel Pentium D 925 uses 95 Watts,

http://en.wikipedia.org/wiki/List_of_Intel_Pentium_D_microprocessors#.22Presler.22_.28dual_core.2C_65_nm.29

In most cases the inside of the computer is dirty, as well as the inside of the Power Supply, and it's fan.

Heat = Wasted Energy
When the Heatsinks inside a power supply, and it's Fan, (To include the fan blades, fan center hub, and surrounding fan cage), become clogged with gunk, the cooling capacity of the power supply drops tremendously.

Since Heat = Wasted Energy the power supply tries to keep up with the power load demands.
Eventually components inside the power supply fail.

(Usually the Electrolytic Capacitors are the first to go)

The power supply inside a Pavilion a1620n is a common SMPS. Switched Mode Power Supply.

http://en.wikipedia.org/wiki/Switched_mode_power_supply

The style is the common ATX, that is used in over 90 percent of desktop computers. (ATX 12V)

The Wattage is 300 Watts.

Should you like help in finding a replacement power supply that is affordable, and reliable, just state so in an additional comment.

I do advise staying away from the cheap generic models, as they can fail in 6 days to 6 months. ($20 to $25 range)

My pc turns on but wont boot up was fine one day would not work the next?


Does it show the hard drive in the bio's? If so and you have the operating disk,,, load the drivers from the disk and when prompted, use the repair mode provided therein to check disk (CHKDSK) It will scan and repair any defects that may be causing the program to not load.

No Video Detected for EMachines 2240


Make sure your connections to the motherboard are secure.
Is this an integrated video or a separate card?
In my experience, if the video does not work, it can be a bad power supply (shouldn't be it if your replacement supply was new).
If the video is integrated, it could have been damaged when your old power supply quit.
If you have access to another video card, try it.
Next step is to disconnect all the stuff except the memory and video and try the machine. Should get something on the screen. A bad CD or bad hard drive could keep the video from starting.

Gateway 831gm not booting. Fans come on but no boot process.


2 questions:
When you say new motherboard do you mean an actual new motherboard or new to that machine, but came from another used model?
When you say you tested the power supply do you mean with a voltmeter/ammeter or put it in another computer and it worked?
I worked on several gateways with similar problems and it boiled down to motherboard issues.
I tested it by replacing the power supply with a bigger (used) power supply and it worked great (for 1 time) and then put the other power supply back in to confirm my diagnosis and yep it wouldn't boot. The next morning I was going to run some virus/malware cleanup and installed the other (known good) power supply and it would not work. I tried all day to get it to boot and it did about twice in a 4 hour period. When it did run it would run great but any attempt to restart it would cause it to crash. No ryhme or reason, it would not fail the same way more than twice. Sometimes beeps, other times no beeps, sometimes it would start up with no video (could hear the Windows starting sounds) other times it would start up normal. I could let it sit and it would start or I could keep trying in sucession and it would eventually start. Some times the fans would slow down from a roar, sometimes they wouldn't. So with a known good power supply that had 150 more watts than the original I diagnosed it as a failed motherboard. But if you have put in a brand new motherboard then I would replace the power supply, because a bad power supply does not mean no power, just not enough power. Please post back and let us know what you find out.

PC seems powerless except.....


This sounds like a short of some kind or bad power supply or motherboard.
  1. Take any components that are not necessary to boot the computer. Try turning it on again
  2. Try taking all parts (motherboard, power supply) out of the case and then put them back in (I know that sounds weird, but it has worked twice for me before).
  3. If you get to this step, either the motherboard of power supply is shot. The easiest to try would be a power supply. Replace it if you have one laying around or borrow one out of another machine for troubleshooting purposes. This is assuming they are standard ATX power supplies.

NO BOOT


I believe you power supply is bad and needs changing,,
however try this first before changing the power supply
unplug your system.

1.) Open up the computer
2.) remove the memory
3.) Remove the mainboard battery 4e78012.jpg see the silver pin to the right> pull that ayaw from the battery and it will popout

4.) hit the power button 5 times
5.) put your memory and battery back in
6.) put your powercable back in and try booting it..

IF THAT FAILS,, REPLACE YOUR POWER SUPPLY.
