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 your hard drive boot up

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 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 ?

even something as small as an electrical extension or a faulty fan lead can cause this problem

a computer needs all of the data and electrical current to travel through every working device and to have an end to be able work properly

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 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

make sure the CPU central processing unit has thermal paste and dust free and is securely seated

make sure your computer ram modules are securely seated with no dust in sockets also Cmos battery has charge with no dust in the socket some motherboards cmos batteries are soldered in
hope this helps you

I was given Acer Veriton 7500G and the cables are disconnected from the mother body, cables are hanging out. how do i connect each cable

Here is a link to the service manual for your PC. It lists the motherboard connections for all the cables that are needed to be attached for operation. Be advised that the Power LED and Hard Drive LED connectors are polarity-sensitive and if installed reversed will not work. If the mainboard has a "+" sign at one of the pins for the connection, ensure that the cable you connect has its colored wire (usually green for the POWER LED and red for the HDD LED), on the "+" terminal. If they don't work when you power up, you can simply reverse them. Having them installed wrong will not damage the mainboard.

Can connect to Wi-Fi but not sign in with password

If the password is not being recognized, chances are that it was entered incorrectly. Ensure the proper letters, numbers, characters and capitalization is followed exactly. Also, check to ensure the signal strength is adequate (not just 1 or 2 bars) when trying to connect with the router.

No sound sd card asus tf300

Make sure the driver is installed in Windows Device Manager. If not, then install them. If they are then make sure there is not a yellow bang next to the card. If everything looks good, then double check your audio connects, power to the speakers, and volume settings in the operating system. Also, if your system has more than one sounds card, ensure you are connecting your speakers to the right one.

I have a an INTEL Motherboard Model DH55HC. I am installing a basic Internal DVD writer (DVR-A18M) Interface ATA/ATAPi-7. I have the power cable from the POWER SUPPLY in the correct plug. I attach the...

That motherboard doesnt support ATA it supports upto 6 SATA devices which is actually better and faster. You will need to take your DVD/RW back and ask to swap for a SATA and also make sure you buy a SATA cable and good thing is these are actually cheaper and faster. Its actually a very nice motherboard dont be disappointed. Cheers from Scott and plz vote

I moved my home office desk a few days ago. I properly powered down my computer and unplugged everything. When I reconnected everything, the computer won't power up.

1 - Make sure you have power to the outlet you plugged the computer into. 2 - Make sure all of the cables plugged into the back of the computer are firmly seated / attached.
3 - Check that the switch on the back of the computer (usually quite near the power cord) is turned on.

It wont turn on!

Ensure that teh laptop is well connected to power adapter.

Try connecting the laptop with power adapter and no battery , if the laptop starts then you have a defective battery.

Ensure that you have no CD inside the laptop, a bad CD can prevent system from booting.

Also remove all USB devices attached.

In any case, unless the problem was caused by a CD or by a USB device, call teh seller and ask to replace the laptop, as it is new and it is faulty.
