Re: power failure

This is a power supply issue. Try borrowing a power supply to test first. Then buy a new one and replace.

When i on my PC desktop, go into the windows, my PC will close and then restart, then close then restart? what's the problem?

Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive power and data cables IDE SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they could be faulty

computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error

even something as small as a faulty electrical or fan lead can cause you problems

motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working

also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in

check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat

Thermal compound is a sticky paste that is placed directly onto the CPU.

Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.

This compound is an inexpensive solution and can be found at any local Radio shack or computer repair center

another possible reason could be a memory dump you might be running to many programs at the one time putting to much strain on the CPU central processing unit

scroll to bottom toolbar bottom of screen right click select task manager
applications you will see whats running if you see anything you dont need running select end now

also under processes see what is ticking over again if you see something you don't need to be running end now or you might uninstall that program and some unnecessary programs

not having enough computer ram can cause memory dumps

If you are not sure if a module is right for your system use the Crucial Memory Advisor tool for a list of guaranteed compatible modules.

first you will need to select the manufacturer from a drop down list then select your product line from a drop down list then select the model then click find it will take you directly to compatible ram also you will have an option to scan your system

hope this helps

I have an Antec full tower with a 350W power supply it seems somewhat old...i hooked everything up inside and tried to turn it on but it would not turn on any suggestions?

First, is there power from the power supply? Is the power supply turned on in the back? If there is powere to the Mobo, then the mobo is likely the problem. The cpu fan fan should spin if there is ower to the board.

PC show the message and hang and black screen .

You are going to have to start with basic troubleshooting first.

TAKE notes as to where cables were etc. (digital camera would be useful here)

Disconnect all devices from the power supply EXCEPT the motherboard
Remove any extra cards including video etc.(plug monitor into the on-board)
Disconnect all drives

Power u the computer and make sure you can at least get into the BIOS.

If you hear any beeps these can indicate where the fault is.

Power up the PC and see if the fans are working.
If not then double check the power connections to the board.

If you still have no fans it is time to suspect the power supply as the probable cause.

If the fans worked then you should have gotten a display which told you there was an error and offering you a chance to go into the BIOS. ignore it and shut down the PC.

Now connect one drive only and boot again.
Repeat that until you identify the component that is giving you a problem.

Once you find the problem then remove or disconnect and carry on with the rest to see if another component might also cause a problem

If there is only one problem device then you may want to investigate that device further, Unless you don't mind replacing it

If its not the PSU and your fans are working it may suggest a problem with either the motherboard or CPU

I have a power supply that is turning itself off immediately after switching it on it is a new motherboard as well Any ideas why ?

I think either the MB or the CPU is with problems.

Try (2 after 1 works, 3 after 2 works...):
1) only PSU+MB+CPU and Fan - works? beeps like crazy?
2) add memory - works? single beep?
3) add/connect video - any image?

All other connectors off (disks, etc) only PSU, fan and case buttons.

If you don't get past 1), go back to the store and have it tested/returned there.

Raidmax Sirius case not turning on

Recheck the wiring. Make sure the fans are all plugged into the proper place. Then try reseating the RAM, video card, & cpu. Make sure you have applied a good thermal paste between cpu & heatsink as overheating can cause the system not to boot. Hope this helps & please remember to rate my answer. Thanks.

There can be several causes for your problem.
So I will walk you through checking the most likely causes.

If you have the manual for your Motherboard it will be useful for reference purposes, otherwise you can find it at intels website with the following link.

First thing I would check is that ALL of the power connectors are in place and secure. In particular check the 20 pin ATX connector and the two 12V connectors (2 four pin square connectors) right next to the CPU.

I'm not sure if the Aux PCIe connector at the bottom of the board needs to be connected if you have just one Video card. If your Video card has its own power connecter make sure that is attached and secure.

When installing the motherboard there should have been some standoffs you needed to install, more than likely at least nine of them. if any or all of them had a metallic ring around the screw hole then they are important that you have a standoff under it and that it is secured with an electrically conductive screw(Any that came with your case that thread into the standoff should be good).

make sure that that the processor is fully seated and the heatsink (Cooling block if building a water cooled system) is attached properly with a thermal pad/paste.

make sure the fan for the processor is properly attached to the heatsink and its power leads are connected to the CPU fan power connector(On your board the connector is a four pin) the one on the fan may be 3 or 4 pin depending on in it is speed adjustable by the BIOS

there are lockdown latches for your RAM and Video cards, they should come up and fully seat into the notch on the video card and RAM modules.

If you don't have enough RAM modules to fill all 4 slots at once, use the one next to your CPU first then the one the same color as that, then the next one up and its like colored. if you want your RAM. If installing in pairs its important to make sure they have the same specification (Size and timings)

Connect your case fans to their repective pins on the Motherboard.

Connect the power and data cables for your Optical drive(s) and Hard drives.

Make sure the case wiring is attached and properly oriented on their headers

attach the USB & or Firewire(1394) connectors to their respective headers (Be sure not to interchange and attach a 1394 cable to a USB header or vice versa) [That could kill the connectors or fry the Motherboard]

Now I think your ready for a test run.

leave the side panel off and connect everything up and try to boot, If you see a light on the motherboard then thats a good sign that all of the power connectors are properly attached and that the Motherboard is OK.

If you fail to get that light the motherboard may have been damaged when you attempted to power up and the CPU wasn't properly seated

If it attempts to start but shuts down right away, you may have a damaged CPU (Processor) unplug everything, remove the processor(Make sure you discharge any static electricity by placing a hand on the side of you Power supply before touching the CPU) turn it over and look to see if any pins are bent (If so you can straighten them again by using a mechanical pencil. Just pull the lead out and slide the pencil over the pin and adjust to as straight as you can.

Reinstall the processor clean off the old thermal pad/paste from CPU & Heatsink with a Qtip and some rubbing alchohol. Let dry and apply a new thermal pad or paste. If using paste put an amount about the size of a dime over the Core of the CPU if you want to spread it use something other than your finger[oil from skin can affect the pastes conductivity] then reattach Heatsing and fan

and give it another go. If it still does not work, you may have damaged your CPU electrically and it should be replaced(maybe under warranty, since its brand new)

Hope this helps

Raidmax 500w power slowly died, then wont turn back on.

1.-Your CPU fan is working?

2.-Your Power supply fan is working?

If not and following your description I think that you have to replace your power supply.

If you have the light on in the motherboard doesn't mean that your power supply is good.

Check the first to points above and if 1 and 2 are not working

Replace your power supply.

Let me know how it is going!

Thank you for using FIXYA!
