Do you get any lights on the PC when turned on?
Hopefully you have resolved this by now but if not....
Not a lot of info to go on here but here are some things to check...some may be obvious I know but worth mentioning...

Check the following:
1- Is there power coming from where you plug it in (can you plug something else in the outlet that works?)
2- Is the power cord plugged securely in the back of the PC? (Unplug and replug connector to be sure)
3- Is the red switch near the power plug on the back of the PC set to 115 or 230? (Try changing this and then setting back to 115)
4- Is the power supply plugged into the motherboard inside the PC?

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.

Tells me I'm in a power saver mode. Screen is blank. Model is 2241V


That message comes up when the monitor doesn't get a signal from computer, and enters power save mode until computer comes on. This usually means that the computer's not starting up when you turn the power on. It may also mean that some problem has occurred with the computer's video circuitry.

Begin by checking that the computer is actually starting up properly. Look for the normal startup signs (lights on the computer showing power and disk access, fans running, sounds through the speakers). If you're sure that the computer is working and getting into Windows, try another monitor. This will tell you if the monitor is bad or if there's a video issue with the computer.

Hello, When i start the computer its starts a


Oh geez, you have some work ahead of you.

I would somehow acquire another video card (ask a friend :)). Put that in and see if your computer boots up. If that still doesn't work its either the CPU, or the Motherboard.

I would take apart the heatsink, remove the CPU, reseat it and see if it works.

Let me know! ill help

When i switch on the monitor the on/off button blinks and i don't get a picture. johanalvemalm@people.net.au


Most monitors will behave that way if they don't get a signal from the computer so there's nothing to display. A quick check of the monitor itself is to disconnect the signal cable from the computer and then turn the monitor on. Most monitors will display some kind of a message that there's no input and to check your cable connection. Then the power indicator changes color as the monitor blanks out.

You will probably find that your computer isn't starting up when you turn on the power. A common computer problem is that it will turn on when you press the power button, showing a power light and you'll hear the fans inside start running, but it never actually starts running. Then there's no video to the monitor and you see the trouble you described.

The monitor may still be bad. If everything seems to be starting normally and you hear the Windows startup sound through your speakers, but the display stays blank, try another monitor. If that one works, you'll need to have the bad one serviced or replace it. If the test monitor is also blank, the video circuitry in your computer has failed. If the video is built into the motherboard, you can install a plug-in video card as a replacement.

If the computer is turning on but never starts running, that can be a pain to figure out because several things can cause the trouble. The most frequent causes are a bad power supply or motherboard. Bad RAM or a defective drive or other device connected to the motherboard can also keep the board from starting up. The processor itself can fail, but that's not common. I start by removing everything except for the power supply, processor and fan to see if the motherboard is starting. If the motherboard doesn't give a "no memory" error (usually a long beep), you need a power supply or motherboard. Otherwise, the basic hardware is fine, and you can start replacing parts until the trouble comes back, and then you'll know what caused it.

Good luck, and thanks for using Fixya!

I have a blank screen on my HPf1905 monitor. I have a HPm7330n computer. How do I know if its the monitor or the video card? Monitor shows a message no input signal,then goes to sleep mode.


if the message you recieve is no input signal if only means that you have a problem with your video card, the monitor is fine but you need to have your video card check

Pc beeps 4times y?


4 short beeps
Your problem could
be a bad timer. The system timer failed to work properly. It will
require motherboard replacement.

1 long and 3 short beeps
Memory test failure. An error has been detected
in the memory over the first 64K. Try replacing the memory, and if
that doesn’t do it, the motherboard.

Beep codes are the beeps you hear from the
PC speaker when you turn on your computer. They are your computer’s way of letting you know what’s going on when there is no video signal. These codes are programmed into the BIOS of the PC.

The beeps are probably BIOS beep error codes. Through a series of long and short beeps the computer communicates computer problems that occur early in the startup processes. It's likely the problem isn't your monitor but something in your computer box itself. If you can tell us what the pattern is we can start diagnosing your problem. We'll also need to know the manufacturers name, the specific model computer you have and what operating system you are running.
