Boots up without images on the screen

The graphics card in the PC is very likely faulty. It is possible to remove the graphics card and reconnect the monitor cable to the onboard graphics. Look on youtube for help on removing the graphics card (try a search for iq772). The monitor connector is at the front of the motherboard, near to the graphics card. re-connect it to a similar connector to the left to use the on-board graphics.

Changed lan settings in post now my bios and xp wont launch

Turn the computer off.
Disconnect the AC power.
Look closely at the motherboard.
Look for 3 pins in a row, with a jumper between 1 & 2.
This is the "BIOS RESET" control.
Move that jumper to connect 2 & 3, for 5 seconds.
to reset the BIOS to its "default" settings.
Move that jumper back to to the 1 & 2 position.
Reconnect the AC power.
Turn the computer on.
Enter BIOS SETUP, to confirm that the "default" settings have been restored.

My touchsmart iq770 wont run windows vista unless im in safe mode and i have lines through my screen

Go to and look up your computer.
Download and install the Vista drivers.
If you don't see Vista drivers the computer won't run Vista. Go back to XP.

5 beeps are coming and after some time five beeps are repeating.system not booting

Hi ,

When you hear 5 beeps while booting or turning the computer off it is related to the operation of critical motherboard components - such as the CPU.Please try these steps to try fixing this problem .

Open up the computer tower and then once the side panel is out a test on the motherboard needs to be done and to do that look for the memory cards(Ram ) which would be green in colour,4 inches long and would be inserted in a slot that has clips in either ends that holds the card in the slot firmly.There can be one or more than one so remove the memory cards and then turn the computer on by just connecting the power cable,you should hear long beeping noise if you dont hear any then the motherboard needs to be replaced or needs to be serviced.

allthe best

HP Pavilion 7965 not booting: Just replaced PSU with one that works just fine (got it w/o a power supply) and after checking all connections, powered it on. It turned on and immediately beeped for about a...

You have to have ram memory in, for the computer to operate at a basic function. To get to the BIOS POST screen.

When changing out hardware do you have the power disconnected from the computer?
Yes, I know, but I have to ask.

Also, do you follow anti-static precautions before sticking your hands inside the computer?
Touch the metal frame of the open computer case before reaching inside?

Your body carries Static electricity.
Static can fry out the hardware components inside your computer.
Especially the Processor, which is the most susceptible hardware component to static shock.

1) Computer unplugged from power. Video card removed. Monitor plugged into VGA port on the motherboard. Ram Memory installed. Harddrive data (Interface) cable disconnected, and power cable. Same for any optical drive/s.

Press the Power On button in, and hold it in for a count of Five seconds.
Let go.
Do this procedure 2 more times.

What you are doing is clearing CMOS Error Codes, and resetting BIOS Setup back to the factory default settings.

Plug back into power. Wait 1 minute. Turn the computer on.

Do you get the BIOS POST screen? Let's start from here.
