The most important thing that I was thinking about is that you told me you were using a PENTIUM over a mother that is for AMD processors, make sure of that because if its as you told me, then you will never be able to fix that cuz its impossible for an INTEL cpu to work on an AMD plataform...

well it seems that if everything is well connected then your either your power supply is failing or not reaching the power demands or your motherboard is completely down... This is one of those cases where you only have to try and see what happens, thats why its hard for me to say whats happening whithout trying somethings...

things like: mother just with cpu ram and vga adapter over a table and booting it up. (what we already tried), then a bios restart.. (with the cmos jumper)... try a different power supply in case you have one.

stay in touch

Where can I get instructions to put unidentified tower together?


You have all the pieces .. motherboard .. cpu .. ram .... heatsink/cpu fan?

Place the cpu into the motherboard socket. Note that it only fits one way. Check the pins on the cpu against the holes in the socket. Hold it in place with the securing catch/lever that you will see on the side.


Smear some heatsink/cpu paste onto the top of the cpu. The heatsink paste is basically a 'heat resistant glue'

Put the cpu cooling fan onto the cpu and screw it into position. Or, it may have a securing lever to hold it in place.

Put the RAM into the ram slots. They only fit one way. Make sure they are firmly in place.

Put the motherboard into the casing. Align what holes you can and use the screws that come with the casing to secure the motherboard.

Connect the casing power supply to the motherboard. Note that it only fits one way.

Connect the cpu cooling fan to the motherboard connector. It only fits one way ..

Next, look at the leads that are just lying loose .. the small female 2 pin connectors will be marked 'PWR' ..'LED'..'RESTART' ... There maybe 8 of them.

On the motherboard identify the block of male 2 pin connectors. The female connectors must connect to them. You'll need good eyes and probably a flashlight, as the writing on the motherboard is small..

If you are connecting a sata hard drive, connect to the motherboard connection that says 0. Connect your dvd drive to '1' Again, notice that sata leads can only fit one way.

Then connect any video or sound cards to the motherboard (if any).
Just look on the motherboard for anywhere the connecting wires will attach. You won't go far wrong.

The casing won't come with instructions of 'what to do' as such. If there were instructions there it would relate to pin/hard drive connections.

What you CAN do is a google search. If, for example, your motherboard is an ASUS 123456 .. search for 'ASUS 123456 motherboard connections'. Or log onto the motherboard manufacturer's website ..

Dell VOSTRO 460 beeps during startup and will not startup.


many times if the fan over the cpu chip on the motherboard fails to run or blow, an beeping alarm will begin and PC will not start. the cpu has to be kept cool so if fan fails the startup is stopped. have found lose wire connections from fan to motherboard terminal, or power supply may be blown, try checking those first. if nothing lose then wiggle those wires to see if the fan starts.

What makes 511-cpu fan not detected and 512-chassis not detected


Are you seeing this error on a system you built or a pre-built system? If it is a pre-built system, check that the fans are running. Next check where the fans are plugged in, the CPU fan must be connected to the CPU fan connector on your motherboard. The chassis (rear case fan) only needs to be connected to the motherboard if you want the monitoring/PWM (modulated fan speed) option. If your CPU fan is powered directly from the power supply, change this.

If this is a system you built or recently updated the case, check your fan power connections, as above. Next check the fan speed. My ASUS board will give the "CPU fan not detected" error if the CPU fan speed is too slow. A different CPU fan will solve the problem. (I got my fan with the CPU; it works fine.)

I hope this helps. Please add a comment with more information about your system for more assistance.

Epos won't turn on


b> The PSU might be the culprit

WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Remove new hardware If any new HARDWARE has been recently added to the computer, remove that hardware to make sure it is not the cause of your issue. If after removing the new hardware your computer works it's likely the computer is either not compatible with the new hardware or a system setting needs to be changed to work with the new hardware device. Remove any disks or USB devices Remove any disks, CD's, DVD's that are in the computer and if any USB devices (Ipods, drives, phones, etc) are connected disconnect all of them as well. Reboot the computer and see if anything changes. Disconnect external devices. Remove everything from the back of the computer except the power cable. Turn on the computer and see if it beeps normally. If the computer has never beeped keep the monitor or display connected to see if any change occurs. Check all fans Make sure all fans are running in the computer. If a fan has failed (especially the heat sink fan for theCPU) your computer could be overheating or detecting the fan failure causing the computer not to boot. Check all cables Verify that all the cables are properly connected at that there are no loose cables by firmly pressing in each cable. All disk drives should have a data cable and power cable connected to them. Your power supply should have at least one cable going to the motherboard. Many motherboards may also have additional cables connected to them to supply power to the fans. Disconnect all expansion cards If the above recommendations still have not resolved the irregular POST, disconnect the riser board (if applicable) and each of theexpansion cards. If this resolves the issue or allows the computer to POST connect one card at a time until you determine what card is causing the issue. Disconnect all drives If you were unable to determine by the beep code what is failing or do not have a beep code disconnect theIDE, SATA ,SCSI or other data cables from the CD-ROM ,Hard Drive and Floppy Drive from the Motherboard. If this resolves your irregular POST or generates error messages re-connect each device until you determine what device or cable is causing the issue. In some situations it can also be a loose cable connection that causes the issue. Remove the RAM If you continue to to receive the same problem with all the above hardware removed, disconnect the RAM from the Motherboard and turn on the computer. If the computer has a different beep code or if your computer was not beeping and is now beeping turn off your computer and try the below suggestions. Making sure to turn off the computer each time you're adding and removing the memory and then turning the computer back on to see if the suggestion resolves the issue. Re-insert the memory into the same slot. If you have more than one stick of memory remove all but one stick of memory, try rotating through each stick. Try one stick of memory in each slot. If you're able to get the computer to boot with one or more of the sticks of memory it's likely you're dealing with some bad memory. Try to identify what stick of memory is bad and replace it. If you're able to get memory to work in one slot but not another slot. You're motherboard is defective you can either workaround the issue by running the memory in a different slot or replace the motherboard. Power cycle the computer In some situations a computer may have power related issues often caused by either the power supply or the motherboard. To help determine if this is the cause of your issue try turning the computer on, off, and back on as fast as possible, making sure the computer power light goes on and off each time. In some situations you may be able to temporarily get the computer to boot. This should only be used as a temporary workaround if you're able to get this to work. Often this is good for users who may have not done a backup and need to get the computer up one more time to copy files before starting to replace hardware. Disconnect and reconnect the CPU For users who are more comfortable working with the inside of their computer or who have built their computer one last recommendation before assuming hardware is bad is to reseat the CPU by removing it and putting it back into the computer. Bad motherboard, CPU, RAM, or power supply If after doing all of the above recommendations you continue to have the same issue unfortunately it is likely that you have badMotherboard, PSU, CPU, orRAM. The next step would be either to replace these components or have the computer serviced. If you plan on doing the repairs yourself or you are a repair shop it is suggested that you replace the Motherboard first, RAM, CPU, and then power supply in that order or try swappable parts from other computers. Hope this helps. b>

I have a Dell Inspiron 530. Was getting 2 quick beeps on start up and loud fan noise. I replaced the cpu fan but the one I bought did not have the right plug for the motherboard connection. I had to modify...


This model (as well as many other Dell desktops) has a DUAL SPEED CPU fan. If the motherboard detects that the CPU temp is running hot it will increase the speed of the CPU fan to lower the temp of the CPU. You should do a Google search for the correct CPU fan and purchase it and install it back into your computer.

CPU fan turns for a few seconds and stops, pc will not turn on. Have tried a good PSU, same issue. Removed all connection to motherboard apart from 20 pin, 4 pin power + cpu fan and PW switch: same issue.


1. First of all Remove dust from your CPU fan and try again if issue has been not resolve

2. Second test your SMPS by the help of Green & Red wire. In case fan is turning properly it mines your SMPS is ok

3. Third & last kindly replace your SMPS For the same.

Pc wont boot up, instead a red light flickers.


Flickering LED means power supply is overloaded with something. It might be inside of the supply, but sometimes it is something else. Try that:
1. Disconnect everything from the motherboard except power supply and power button;
2. Disconnect all power connectors from all drives;
2. Remove any cards from the motherboard so all you have is power supply and motherboard with CPU and RAM, nothing else. You can keep connected the monitor and keyboard;
3. Press Power button. Will motherboard turn on normally?

If no - check electrolytic capacitors especially around the CPU, if some of them are "popped" replace them.
If yes - connect drives and cards one per time to localize the problem.

New cpu fan has 3 prong connecter, old has 4. what is,or does the 4th blue wire have to be connected?


Hi,
You can connect the CPU fan as normal but it can only run at one speed and voltage hence only having 3 wires.
Your other CPU fan which had 4 wire was able to run at 2 different voltages and speeds and are mainly used to keep the noise down and run quietly.



Regards.
