Pc don't boot up and the monitor starts up then powers off. i hear the hard drive start up

Posted by on

    Last evening I downloaded an updated bios driver for my Dell Dimension 8400 desktop. When the driver installed, the computer rebooted automatically. When it did, the keyboard lights flashed then went out, the monitor screen was black, there was intermittent buzzing from inside the computer, and the fan sounded like a 747 taking off.

    I removed the four memory cards and reinstalled them but nothing has changed I haven't slept all night worrying about the data on the hard drive. Can anyone suggest a way to get this computer back to normal?

    Thank you.

Desktop runs but won't boot


Normally if the hard drive is bad you will get some type of message on the screen.

If it sounds like it is running but the screen is blank, then try another monitor. Maybe the monitor is bad. Try another monitor. Borrow a monitor from a neighbor, friend, relative or co-worker and put it on the computer. If the borrowed monitor works, then your old monitor is bad. If the borrowed monitor does the same thing, then your video card is bad.

If it does not seem like it booted up all the way then try the steps below.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button. And if that's true maybe you was operating off the battery the last time you had it on and since the power cord is bad, it was not charging the battery so the battery is drained and the power cord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.



Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

My friend karen press the power button, thre is no power... there blinking lights on the back of the computer near the fan power ...


Do you hear the harddrive start up? When you push the power button (or switch on the back) do the lights go out? If you hear fan running and hard drive start up then the computer itself might be on but the monitor isn't. Check the power to the monitor, the connection between monitor and computer to make sure they are all on and connected.

If you don' t hear the fan running then you have other problems. Any blinking lights would indicate something is getting power. I'm assuming the computer was working before the power button was pushed... If the monitor is actually working, you could hook up another monitor to check too then you have other problems but need more info to know what that could be.

would need to know the answer to the above questions as well as if it was working before, what was done, what changed between it working and this problem. Also what age the machine etc.

Can't get past an Analog Self Test Feature Check on my screen


This means your monitor is not receiving a signal from the computer. You now need to determine what the problem with your computer is.
Check to see if it is starting up (booting) correctly.
Can you hear the hard drive spin up?
Can you hear the system fan?
The problem could lie with any hardware component. I would suggest removing the cables from all internal hardware (hard drive, CD, etc.). Now see if it boots.
If all you have hooked up is the CPU, video, memory and it still won't boot, the problem lies with one of those 3 components or with the motherboard.

Trying to change out power supply on a Gateway DX4822-01. Can hear hard drive spinning, but not getting anything on screen. Unplugged it yesterday. Now wondering if one of the 4-pin needs top be...


Trying the easiest solution first - It sounds as if the power is getting to the hard drive, but the information is not getting to the computer.

Is the IDE/SATA cable attached to the hard drive AND the motherboard?

Are the connections tight?

Is one end of the cable reversed - does pin 1 on the hard drive correspond to pin 1 on the motherboard?

Are the jumper settings on the hard drive set properly - Master/Slave/Cable select?

Are you replacing an IDE hard drive (uses a wide thin ribbon cable) with a SATA drive (uses a narrow, fatter cable). Can your motherboard handle a SATA drive? Perhaps you are trying to install the incorrect hard drive?

It will not start even after I replaced the power


Before anything else, open your case and make sure all power and data cables going to motherboard, disk drives, etc are firmly seated, and remove and re-install memory sticks in the same locations. Sometimes temperature changes inside the PC can cause these connections to loosen. If that doesn't fix it, do you hear the noise of the cooling fans coming on? If you do, check your monitor for a green light. If you get a green light on the monitor and fans are powered up and running and you get nothing else it could be a hard drive issue. Try booting from CD in that case. If fans come on briefly and then shut off, or fans stay on and you have no green monitor light, this could indicate an issue with your processor or motherboard.

Emachines desktop fan runs high speed at power up


I would start by replacing the power cable to the monitor. If you don't hear your hard drive then maybe the power cable to your power supply is bad or you have a bad power supply. So first make sure the cable that goes from the wall to the power supply is good. If it is good make sure the power supply is turning on. If it is then make sure that the power cable from either the wall or your computer to the monitor is good.

Yellow power light on HP SR1420NX


For reasons yet to be determined, your computer is not talking to your monitor.

This could be the monitor cable came loose from the tower (this is our favorite, because it is such an easy repair), or something on the motherboard (that is, anything) that is not functioning and preventing your computer from starting.

Unplug the connecting cable, and plug it back in again, making sure that it is seated properly.

Do you hear any sounds besides the fans? You should be able to hear the faint clicking of a hard drive starting up also. If you hear this, the problem is not in the computer, but in the communication to the monitor.

Good luck

Hp laptop computer will not boot up. The power comes on and you can not hear the hard drive start spinning - no hard drive clicking either. You can hear the fan start blowing....but nothing on the lcd...


You hit the problem right on the head, NO BOOT. All computers have to have a system disk to read whether it is on a floppy or hard drive. your computer is not reading your hard drive. It either is really screwed up from the boot, or it has been formated and has nothing to read. Try installing a new copy of windows or inserting some type of bootable disk. if that works, Install your windows operating system. Insert a disk in your D drive or your CD drive letter and turn the computer off, restart the computer and the disk should boot your computer. Good Luck.
