That means that the input from the monitor has no read able signal
Either the monitor is bad or the onboard or video card
Take the monitor and hook it up to a different PC to see if it works or hook a different monitor into that PC, that will ID which problem you have

Check to see if you're running the latest bios revision. It's on HP's support page for your model.

Open the desktop, and re-seat the memory. Let me know if that works.

Some newer viruses block web sites, including sites of most popular virus removal software. If you have a virus removal tool on your machine, unplug from the web and try to run a full scan as the first step.

Your fan speeds up and slows down in response to temperature inside the computer. More so the CPU.

I would suggest getting a can of compressed air made for computers

take it outside, take of the side and blow all the gunk out of there, Really go to town around the fan (you might want to wear eye protection)
While you are in there just check that the CPU cooler itself is not loose

If it is it will have to be re-seated.

If it needs re-seating don't just take it off and put it back on as that might make things worse with your temperature problem they have to be cleaned and new thermal grease put on ($2-5)

DON'T remove the CPU just the fan/cooler assembly.

You must clean both the surfaces without scraping anything off. Use isopropynol alcohol and cotton bud sticks until both surfaces are clean, you can use your finger nail to scrape harder residue if you wish but nothing else.

DON'T pour the alcohol over the CPU

Now apply some new thermal grease (most computer shops have it)

Be careful about how much you put on

Here are some basic instructions

Once you have re-assembled your cooler and re-connected it check everything is OK and power up the computer.

If everything went to plan you should now be back in business

Seems like your Ram or CPU Chip is either out or wasn't seated in its slot properly. You may want to open it back up and check for any mistakes.

please try reinstalling the monitor drivers that would have come with your HP Pavillion ,actually the software in your pc is fine and by adjusting the refresh rate and colour setting if its not working good means that your monitor drivers has to be either updated or reinstalled

thanks and regards

It's usually a hard drive activity light. The light blinks when you're reading or writing to the hard drive.

yes, you can providing it is the same family, ie ddr2888 or 553 ect but might slow machine down, It is always better to do an exact match,

What is the type of connector for the dell monitor? IS IT VGA or DVI. The HP computer is a notebook or desktop. Are you connecting to the onboard video or video card.Check if the monitor is passing self test feature. Then try connecting with HP computer. Good luck

You will have small hole on the drive. You may need a neddle to put it in. This will help to eject the disk out. But if this is a regular process then probably the gear mechanism is at fault which needs to be taken to a service center for repair.

Do you still have the MB CD with all the drivers still with you, if so then run that CD once. Secondly soundmax has many versions running so look for the driver that was released during the time you bought your PC. Many a time you got to manually add the hardware and then its driver for it to function properly....................sodeep

pci

Attempt to boot the machine in Safe-Mode.

While powering up continuously hit F8.

You will get a Boot Option Menu, Select Safe-Mode boot

If you can get into safe-mode I would suggest to try doing an online scan, as it sounds like your issue could be related to malware:

looks like u've done most of the steps.
put everything how it was, change the ram to the next availble slot. remove power, remove bios battery "like a watch battery" wait 10min and put back on and power on see what happens

It's possible that the spring clip behind the power button is broken and won't allow the power button to fully make contact. That's a fairly inexpensive fix. Or, some of the cables/wires could be loose, but I'm thinking (from your description) that it may just be the spring clip.

after you remove the screws the case should pull forward

Take the side of pc off and locate CMOS battery, 3V disc shaped, and check if not flat as your pc will not start at all if it has lost all settings in bios. If replaced battery and still no luck locate on motherboard 'JBAT1' terminal and put jumper on pins 2-3 then back on pins 1-2. This will clear any faulty cmos settings and require you to set time and date again etc. If you still get no boot up, either the power supply or proccessor is faulty; unfortunately hard to diagnose over the net.
