X6dh8-g2+ no video continous beep

Hello here is the homepage:

Try to boot with only one stick of ram at the time, to find the failing ram module.

This is usually caused by a problem with the system memory, or possibly the video card. The memory is more likely--the system complains long and loud sound, if it can't find any usable memory, as there is no way to even start the boot process when this is the case. The motherboard itself could also be the problem.

The mainboard is useing Up to 16GB DDR2 RAM.

Try not to buy cheap ram, they are always failing.

Good luck

The capslock and the numlock leds r flashing continously. the screen is blankWhat's your problem?

The flashing and blinks tells the technician what is wrong with the computer. Most times it's the memory or video card. What is the make and model of your computer?

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, Remove the Battery, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in (leave the battery out) and hit the power button to see if it boots. If it does, you can put the battery back in and let it charge.

Maybe your DC Power Jack which is where the power cord plugs into the computer is bad. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

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

Remove the Power Cord, Remove the battery, Remove the cover that houses the memory on the bottom of the laptop then 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.

Video monitor says there is no input and to check the cable connections. connections and cable are good. Does that mean the video card has probably gone kaput?

It may mean that the video card is bad , but not always the case. Start with borrowing a known good monitor from a working pc and then test the following ... video card, memory chips ect. Does it show screen ever or only goes away in the middle of boot up? try booting in safe mode F8 key if it happenes in the middle of boot up.

HP dx5150 Microtower PC won't start up just beeps

That's what's called a POST beep code. The HP DX5150 beep code info can be found at,

but for your benefit: 5 beeps means you have a memory problem. Take out the DIMMS (memory sticks) and reseat them. Try to boot. If you get the POST code again, you have bad memory (unlikely, but could also be a bad FSB on the motherboard). If you have more than one memory stick, remove one, try to boot, if you get the error, put it to the other memory slot, try to boot...then do the same procedure with the other stick. If you can get it to boot on one stick, you know the other is bad.

It could be a memory problem. Remove and reseat your memory card and try it. If you have 2 memory cards, try starting it with just 1. If that doesn't work, swap so that just the other card is in place and try again.
Try bringing it up in "safe" mode. If that works, you probably have a software issue. Let me know how you're coming along with this and I'll be here to help'
