Question about HP PC Desktops

Open Question

My HP Pavilion a1777c desktop doesn't seem to be getting a signal to the monitor though it seems to be running fine. when you turn it on the monitor says "no input status" and turns off. the cable is fine because i tried another one from a functioning computer and it still didn't work. It has a GeForce 7500LE graphics card. I don't know what is wrong with it. Anyone have any idea?

If the computer is starts up normally other than the no-video problem (that is, you hear all the normal sounds from the computer and the usual Windows startup music), then you probably do need a new video card. According to HP's spec page for the motherboard used, you'll need a PCI-E video card. Don't confuse this with a regular PCI card which has a different connector.

The spec page also says the board has integrated graphics. so you could remove any video card that's been installed and try booting with the built-in video. If everything else is working properly you can use that until you get a new expansion video card.

If the trouble is that the computer's not booting at all even though it's coming on, you'll need to figure out why. This might be a memory or video problem, although these usually cause some beep code if the motherboard gets into its POST (power on self-test). If nothing at all happens, this is often the sign of a bad power supply, processor chip or system board.

Try reseating the video card to see if it fixes the problem.
If it doesn't the the video card is faulty, take the card to your computer shop and get a replacement that matches the specification of your faulty video card, the card would most likely be an AGP card.
On the motherboard you can identify the AGP slot/connector (brown colored) because it does not match the other PCI slots (white colored).

No video on a Pavilion s3620f


Try another monitor that you know works. If that doesn't work it may be your video card or chip.

check to see if your vga cable is properly connected at both ends i.e. at the monitors end as well as the computers end. In case it doesn't solve the issue then your vga port is damaged.

I have a HP Pavilion Slimline s3700y that doesn't always boot. Power is getting to the computer; the light on the back lights up as well as the lights on the front. However, power doesn't seem to...


If you saying "doesn't always boot", most common would be motherboard...
If your motherboard still beeps, then probably some other components has the problem like RAM, GPU card etc., depends on your motherboard.

Hope that give an idea...
