Then check on the motherboard for "popped" capacitors. They look like small barrels upright (in case you didn't know what they looked like)

System unit or power supply?


The computer power supply may have failed. Do you get the "post beep"?

If not- remove the BIOS battery, move the jumper to "Clear BIOS" . Insert BIOS battery, and try to boot. Put jumper back to normal position and try boot again. If you do not get the post beep, swap power supply for a known good one, and try boot again. If it still does not boot and give you a post beep, look to see if there is a removable BIOS chip- pop it out and put it back in.place, this will clean the terminals. Go through and reset BIOS, as above, and try boot. If the system is functional, it should now boot up, but prompt for you to run the setup program.

If it does not boot, the problem is relating to motherboard/processor.

I have a v-epc-001 and when I turn it on it just shows wireless book and a progress bar with 'loading device drivers' underneath it...it never boots to windows


Few computer problems are more frustrating than a laptop that refuses to boot, as troubleshooting becomes infinitely more difficult when you are unable to get into the operating system. By understanding the common causes of laptop booting problems, you may be able to spare yourself the cost of paying an electronics store by resolving the issue on your own.
Laptop computer
Error Messages
If a laptop is unable to boot, there will usually be an error message giving you some idea of the problem's cause. Read this error message to know where to begin in the troubleshooting process. Some common error messages seen on laptop computers during the booting process include "NTLDR" messages, which deal with the operating system, and messages relating to the hard drive and the power supply.

Identifying a Software Issue
If a laptop has trouble booting and displays error messages generated by Windows, the cause is often a failed driver installation or other change that rendered the computer unstable. This type of issue can often be resolved by starting Windows in safe mode, then using the System Restore utility to roll the computer back to the previous configuration. If an external peripheral was recently added to your laptop, such as an external DVD drive, try booting the laptop with the device disconnected, then reconnecting it once Windows is fully loaded.

Identifying a Hardware Issue
Random booting issues on a laptop--those that seem to come and go with no explanation--are often caused by a problem with the hardware. Other symptoms of a possible hardware issue include a system that does not get past the POST screen (the initial monochrome screen displayed when the unit is turned on), or an error message containing the word SMART (this refers to an internal health monitoring system used by hard drives).

Identifying a Heat Issue
For all electronics, heat can be a killer. Heat-related issues can be caused by using the laptop in an unsafe way (such as by putting the laptop on a surface that blocks the air intake port), or by dust building up inside the cooling system. An unacceptable level of noise emanating from the cooling can generally signify that the cooling system needs to be cleaned in order to prevent a more serious issue. If a laptop has a booting problem that only tends to arise after the machine has been in use for extended periods, heat is likely to be the cause.

Prevention/Solution
Do not neglect your laptop's power supply. Laptop power supplies are often quite fragile, and are susceptible to damage from heat (exacerbated by being trapped under a desk or chair) as well as damage to the shielding surrounding the cable. Problems caused by a faulty power supply are often not instantaneous; it can take time for a power-related issue to become evident. To avoid booting problems that may be caused by a power issue, replace your laptop's power supply at the first sign of physical damage.

I hope you find it very helpful. Thank you.

The computer could not read your copy of Windows from your disk-drive.

Either:
* there is no electrical power getting to the disk-drive (check the power cable)
* the "data" cable between the motherboard and the disk-drive is faulty or not-connected (check it)
* the power-supply in your computer is not supplying power to the disk-drive (try different power-supply)
* the disk-drive itself has "failed" (maybe, the motor that spins the disk-drive has failed)

Take your computer to a professional technician for trouble-shooting.

Computer acts like it in standby mode will not power up, made a weird noise according to my daughter and quit


Test your PSU 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 or to shutdown or fail to detect/ boot up a computer hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and 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 even the electrical extensions or just replace them they are probably old and faulty a computer needs its connections to have an end so any faulty leads will end up with a computer error

hope this will help

Alienware Aurora Desktop does not boot, has no HD activity


If the activity light on the front of the tower is not glowing than it can be an issue with the power supply of the PC. Try to open the tower and try to reseat the Power supply cables and check.
You can also try to Reseat the RAM (memory) sticks. If you have 2 Memory stick you can just try to boot the pc with the help of one stick and vice versa. If still the issue persist you can try to do a test on the Motherboard. Simply take out the Memory cards and power on the pc . if you hear a beeping noise than the Motherboard is fine and if you dont hear a beeping noise that it is a faulty Motherboard.

Beeps 2 times & a warbling noise when trying to boot up - unplugging power lead & pressing ON/Off button & reconnecting power lead starts up OK - but it can be OK for several days & then repeats the p


The Cause of Problem:

The Power Buttons electrical circle sometimes just braked it by one of sensors and the result is the 2 beeps and Power Supply is in protected mode error.

The whole computer is turn off but the power button is turn on and this is the nub of the matter. Because if you want turn on the computer you can't because already turn on but just the Power button and you can't do anything.

The solution:
You need just change the Power Supply and don't do anything just the power cable put into the Power Supply after turn off computer.
Finaly change back the Power Supply.

Unable to boot os after power supply change


I would make sure you connected the Power to the main switch correctly it is usually a 3 wire connect, check all connections on the HDD, motherboard, and CD's. also check the WATs rating on your old power supply against the WATs on the new power supply, if the new one is less that is probably your issue.

PLZkeep me posted.

Faint noise on booting.


Try this remove side cover and boot computer listen for any extra noise fan etc. also by power supply
As I think you have a bad bearing in a fan
To temp fix it
remove paper cover over center of fan and put a small and I mean small drop of light machine oil on bearing then replace paper cover.
check if this stops the noise if it does you know which fan to replace.
If it is power supply fan and if you think yourself capable remove fan and do the same to it

Humming noise


IT sounds like the fan bearings are going out already, or have flat spots on them that cause vibration at speed. Try calling the manufacturer and tell them the fan either quit working or is about to quit.
