If you are hearing 2 long beeps or 1 long beep followed by 2 short beeps, the problem has to do with the video card.

But if you are hearing 3 short beeps, it could be the memory card (RAM).

If you suggest to contact the manufacturer for assistance.

Have a great day!

Hi there,

First of all i suggest you to repair your Operating system because i don't think so that it's a hardware fault.
and yes You are right it seems that there must be some file getting corrupted like video driver file.. so try installing it again...

Good Luck!!

thanks

"HP Pavilion m7580" is not


Hello,

To verify whether it's a no POST issue, press NUM LOCK or CAPS LOCK key and check whether the CAPS LOCK or NUM LOCK lights are lit or changes when you press on it. If it doesn't then it's a No POST problem.

However, if the computer screen shows the HP logo or a display then it's POSTING and is experiencing a No BOOT issue.

If the NUM LOCK or CAPS LOCK responds when you press it but there is no display, check the connection between the monitor and the CHASSIS or CPU.

If you have verified that it's a No POST issue because CAPS lock is not responding, you need to open up the chassis to do a troubleshooting procedure. Be sure to unplug the chassis to all the connections especially the power cord. Drain the power by pressing and holding the power button from 8-10 seconds.

Here are the things that you need to do after you open up the chassis.
1. Reset the Memory sticks. Connect the CHassis to the power and monitor. If no go, try turning on the computer without the memory sticks. The aim of this troubleshooting is to see a display on the screen. Any display would be a good sign. If no go. Put the memory stick back in.

2. Remove the CD drive. Turn on the computer, check for development. If no go, proceed to step 3. Just leave the cd drive removed

3. Do the same thing with the other devices like the hard drive and other devices inside. Your aim is to see a display.

Let me know if what happens and I'll get back to you.

Once you see a display. Let me know by replying to this thread.

Hp dv3 boot: no bios, blinking screen


You re having the problem with your hard drive because constantly putting Off your system without following the Shutdown Process will corupt your hard disk and probably crash out so you will have to reload the system by reformating the hard disk or probably change the hard disk and reload it all will be fine ok anything else post back CHEERS

Hp dv1000 doesnt boot


Sounds like the battery is not being charged properly. With a voltmeter, check for voltage at the output of the charger that plugs into the computer. It should read several volts higher than the battery voltage rating. It is common for one of the wires to break just inside the plug. Radio Shack stores have a plug and cord that fits the computer, but the new wiring must be spliced into the original cord (with the correct polarity). Replacement cost for a new charger is quite high! Good luck!

Power Issue turn on and is turns off after 2 sec


Could be a glitched battery. Turn it on without battery installed. Also, to eleviate the memory - take it out. The unit will still turn on. I have to go along with HP support, that's it's probably the mother board. Now all is not gloomy. Hp has extended their warranty on many models, Dv2000-Dv6000 to name a few. Ask for a supervisor.
