Tip & How-To about Computers & Internet

My Computer will NOT start up blank screen?

So, your computer wont start up? What to do? First disconnect all attached devices, Then we must check to see if there is any Power, Try unit in another power point, if Power Point proved OK, then try & change the Power Lead in, proved OK, then Check the Power Supply, do you see the Fan "Kick"? On the Power Supply AND the CPU Fan inside, proved OK, then Check to see if there is power to the Motherboard? Often there are LED's that show if power is ON. proved OK? We must now remove the Power from each device, DVD, Hard Drive, leaving ONLY the MotherBoard connected. OK, So we are at the MotherBoard, it still won't power up, everything else has been removed... now remove the RAM. power up, Proved OK, if NOT, then the RAM is your problem replace.it power ON, Proved OK, If not then your MotherBoard is Faulty, proved OK, then start attaching devices and re-starting & rebooting each time until you find the one that stops the PSU. That is your problem. At each step if you don't have a, proved OK, then, that last step was your faulty bit, replace or remove.
What we have to do is at each juncture we must test each item in turn, and do a reboot each time connecting & disconnecting to prove the faulty bit.
So say we have tested all from Power Socket to MotherBoard & RAM all test OK, then we start to attach the hard drive & it won't power up, or say it was the DVD, This then is the source of your problems.

my pc wont continue booting because of usb overload


what makes you think its usb overload ?

Check your computer's power cable and the power cables to any devices connected to the computer. Make sure all cables are firmly plugged into electrical outlets and into the computer and other devices. If you have an extra power cable for your computer, swap it in to see if your computer's power cable is the problem. Remove your computer's battery, if it is a laptop, and connect the computer to a electrical outlet to see if it will start up. Sometimes a discharged battery will prevent a laptop from powering up. If your laptop still won't power up, remove the power cable, replace the battery and try to run the computer off battery power. Unplug your computer and plug a lamp or radio into the same electrical outlet and see if that device works.
If the lamp or radio doesn't work, the outlet is the problem. Unplug your computer and open your computer's case, if it is a desktop system. Look for loose cables, cards and connections and attach them firmly. Blow out any dust with a can of compressed air. Also, check your computer's memory chips to make sure they are all plugged in and seated properly. Close the case once you are done and plug in the computer. Disconnect any USB devices connected to your computer and try to power up the system. Sometimes a USB device not connected properly will stop a computer system from powering on. Disconnect any new devices recently added to your system. Sometimes new devices will conflict with other hardware within your computer and cause an overload on your computer's power supply. Disconnect any other devices connected to your computer such as the keyboard, mouse, monitor, printer or scanner and plug your computer into a electrical outlet by itself. Check to see if the computer works. If does work, shut it down and connect just one device, such as the monitor. Turn on the computer and monitor and see if everything works. Continue connecting devices until you find the one that is stopping your entire system from powering up. Hope it helps.

i had a problem with my pc it cant power on and only green light in the board i see. any advise please


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 helps

wont start up


We will see if the problem is due to the static charge accumulated on the laptop. Disconnect the power cable from the laptop and also take out the battery. Also, disconnect all the external devices attached to the laptop e.g. external mouse, keyboard, printer. Now keep on holding down the power button on the laptop for the next 30 seconds. Put the battery back and plug the power cable. Now try turning on the laptop and let me know if it works. Thanks!

yamaha rxv-992 receiver wont power up


Disconnect all your speakers from the receiver. Turn the power on, and see if it stays on. If the unit shuts off with all the speakers disconnected, then you most likely have a faulty unit, and it will need to be repaired or replaced.

If the unit stays on with all the speakers disconnected, then you most likely have a bad speaker or a bad connection with the speaker wire.

Starting with one speaker, hook it up, and turn the unit on, and again see if the unit stays on, or if it shuts off. Do this until the unit shuts off when you connect a speaker.

Then disconnect all the other speakers, and leave the suspect speaker attached. Again, try to power up the unit. If it fails with that speaker attached, but works when it is not attached, then that speaker is your problem.
