Question about Computers & Internet

Power prob My desktop computer does not turn on anymore. I've tried everything! I tried other electric sockets in my home & my mother's home, I tried a new power cord, I went on the HP support website & followed all their steps & I opened the side, but everything seems okay. Should I just buy a new one? It's only 14 months old.

Remove all the cable from the back of your cpu accept monitor cable.
remove the ram and reinsert it again.reset your BIOS by removing battery(CMOS). Switch on your computer without battery if starts then change the battery. see whether any capacitor is damaged (pop up).

My pc desktop wont work its my tower cuz i tried the monitor on a different pc so what could it be

I would think it is either you motherboard or your power supply. I would start by looking at the power supply. You can pick up a tester at any electronics store. Even at that most of the time electronic stores will test the power supply for free. If it isn't that then I would check out the mother board.

I am getting a message that says no signal when I turn on computer

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 might be faulty

a computer needs its power and data to travel through every working device and to continue its cycle and to have an end so any faulty leads will end up with a computer error
Click start control panel administration tools computer management device manager scroll to display adapters + to expand you might see a yellow question mark ? or exclamation mark ! or a red x right click select reinstall drivers

you might have to remove your graphics card to make sure the socket is clean
restart your computer the reinstall it this should activate found new hardware wizard
if your computer came with a mother board disk the drivers could be on it

hope this helps you

I have a K8V-MX motherboard. Recently, when i start the computer i will sometimes get no video, sometimes i will. When it doesn't work the monitor just goes into power save mode. Everytime everything...

that happend to me aswell, coz the asus motherboard are like that.
1st unplug all the cabels from the mother board like, harddrive ID and Cd-room ID, leave just the power supply on and try to start Your computer if it doesnt work take off the cabels of USB or anything else that is connected in the motherboard and try to switch it on, if that doesnt work.

get another graphic card and try with it maybe u have prob with ur graphic card, and if that doesnt work take of the motherboard from ur case and try to switch it on like that coz ASUS MOTHERBOARD are really silly sometimes.
hope that Helps.

When i have it plugged in it will turn on and work for 5 minutes or so and then it will turn off and same thing with when it's unplugged. what the problem?

It sounds like your CPU is overheating. You've not mentioned whether a laptop or desktop PC.

Desktop - disconnect everything, take it outside if not raining and clean out all the dust and rubbish you can, I ( VERY CAREFULLY) use a dry paint brush. Pay particular attention to the CPU fan and heat dispersal block. More or less in the middle of the mother board, try and clean out the metal vanes. Also clean around the PSU fan assembly. Check all cables are good and home. Re-assemble and try again.

If it keeps on, its probably best to talk to someone who knows a bit more, or, as above, remove the CPU fan assembly and heat dispersal plate, clean CPU but leave it in the mother board, also clean the heat dispersal plate, (The goo is heat dispersal grease to ensure good contact between CPU and plate) Replace the grease and re-assemble.

A tip is to connect the power supply just before putting the case cover back on, powering up and checking that the CPU fan is working OK.

You can get loads of tips and videos from You tube.

If a laptop, the clear out the dust in the vents on the side and underneath, if that doesn't work, it means dismantling your laptop to clean it out. Your still trying to achieve what I've described above.

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.
