Whenever I power on my computer, it will automatically power off on it's own and keep repeating this. The power supply was replaced, but it was not the issue. What is going on here?

First of all unplug from mains, take out any new hardware, if not then dont worry, you will need to unplug every peripheral from the computer any usb devices ie printer, scanner and cameras, unplug the harddrive and the any cd-roms or floppy drives you have by unplugging them from the power supply and the ribbon cables or sata cables need to removed also, you should only be left with a barebone system as it where, graphics card if not onboard, processor and memory modules,keyboard and mouse, if not sure about disconnecting everything, either write it down before disasembly or take photos of it before you start, so you have a reference to look back to.
Now boot the pc up, if it posts you should be left with a black screen that say "INVALID BOOT DISK" leave the pc like that for a few minutes to make sure it is stable and it is not a bios fault restarting the comp all the time.
If it does reboot, turn the pc off at mains, check how many memory modules you have, they should be just below the processor fan on the motherboard, if you have more than 1 then take all out, remember where each one was as you will be able to assatane if one is faulty and which it is, take the memory module from the last slot and put it into the first slot and reboot the mechine. repeat this until the pc runs stable, you should now be able to see if it is a memory issue and which module it is that is faulty.
If all is well and and there is nothing wrong with the memory and it is still doing the same thing on each memory module then you will have to turn to the processor, it may be over heating, this will cause the pc reboot or shut itself down to save the processor. To check that it is not this, you will have to remove the fan and heatsink from the processor, when you take the heatsink and fan off you will notice a subtance on both, this is heatsink compound, it is used to dispurse the heat through the heatsink and away from the processor, therefore keeping it cool enough to run properly, clean it all up with an alcohol based fluid, and then you will need new heatsink compound, you will be able to pick this up at your local pc store, re-aplly the heatsink compound to the processor, spreading it on evenley to ensure the whole of the metal part of the processor is covered then put the heatsink and fan back into place, make sure the fan wires are reinserted onto the board. Restart your pc.
If all is fine then you should have a stable pc that will stay on and not reboot.
Now turn the power off at the mains, reinsert the cables for the cd-rom and floppy drive if you have one and reboot, once again if all are fine shut down and insert the hdd cables and power cords, and reboot. If all good then you should have a stable bootable pc, if not you may find that its just a simple bios setting conflicting, you will have to reset the factory defaults in the bios, to do this as the pc boots press DELETE this should take you to the bios, look for load default setting or load factory settings, tab to them using the arrow keys click enter and then save and exit the bios, the pc should now reboot. if you still have the same problem after doing all this then it is possible that you have a more seriouos fault, possibly a short somwhere or you may have a faulty motherboard. post back your findings i will be intersted to know how you get on. thanks.

How can I fix my PC, Acer with NMD processor, whenever I try to power it on it fails. I have tried to check the power supply but it seems ok.


Sometimes the on board battery that keeps the BIOS going when the computer has no power can fail. This can stop the computer from starting.
Open it up and look for the battery,get the number, get a new one (should be a couple of bucks) and then change it. Leave power on otherwise it will reset BIOS. What I mean is leave it plugged in and power on to do it even though the computer is not starting.

Thus AVR part of the computer?


AVR = Automatic Voltage Regulation

It is not part of the computer. You buy it separately.

It protects your computer from power surges,
thereby increasing the durability of that equipment overall.

My imedia b2217 will not boot. Is the motherboard dead? Whenever I switch on the computer nothing happens. No lights, no fans, nothing at all. I have replaced the power supply but still nothing


Hi i'm Basti,

How bout the fan for your power supply, is it running? Try to retrace the cables to motherboard and make sure its tight. Change or use another power supply if possible.


Keep me posted. Hope this helps.

Computer keeps shutting off every five minutes or so


Computer may be shutting od due to following reasons:

Computer Virus
There are higher chances of a computer shutting down due to the interference of a computer virus. The virus gets into the computer and fiddles with crucial sections of the operating system, which may cause the system to shut down automatically. You need to install a good antivirus software and get the computer scanned thoroughly for any malware and viruses. Also see to it that the operating system and all hardware drivers are updated.

Power Supply
The computer power supply unit is an equipment that is installed in the cabinet to provide power to the system for operation. Your computer can shut down, if there is not enough power supplied to it for handling the programs running. If you are using the computer for running intensive software such as PC games, the system would require more power than what is actually available. Another reason can be overheating of the power supply. After the power supply is used for a substantial period of time, there is a possibility of dust getting collected inside it. And this may cause it to overheat, resulting in the shutdown of the desktop computer. If the power supply is at fault, you may need to get a new one installed.

Overheating of the Motherboard and the Processor
As with the case of dust getting collected in the power supply, the computer motherboard and the processor can also collect dust, which may be the reason for their overheating. This may also be one of the reasons why your computer keeps shutting down and restarting. You need to open the computer cabinet and clean the dust off the computer parts. The CPU board and the processor can also overheat because of many applications running. If this is the case, then it is suggested to keep the running of applications as less as possible or increase the size of Random Access Memory (RAM). Bad capacitors on the motherboard is also one of the reasons, why your computer keeps shutting down very often.

The 'Automatically Restart' Setting
If you are using Windows XP operating system, there is a setting that indicates the computer to reboot if it detects an error in the system's operation. In order to check if this is the problem, click on 'Start' and 'Control Panel', then select 'Performance and Maintenance'. Click on 'System', then the 'Advanced' option, and select 'Settings' from the 'Startup and Recovery' section. You will find an 'Automatically restart' option, which you need to uncheck for preventing the system from rebooting. Read more on computer keeps restarting on its own.

These were the possible reasons, why your computer keeps shutting down and rebooting. You also need to check if the power cables are properly connected to the cabinet and to the UPS, as loose connections can also be a reason for system shutdown. The most common cause of the computer getting shut down or restarted is due to overheating of the power supply and other internal computer parts.

Dimension 3000 won't boot until it gets warm


There's one way to find out - this is a list of power supplies for your unit on ebay, swap it out to see if the problem persists.

If you want to do it at the local level just find yourself a 400w ATX power supply that you can take back after testing (your machine may require a specific power supply and the ATX may not be mountable in your PC).

Post back with your findings.
