A thing known as BIOS or Basic Input Output System or system BIOS has been configured for security. When after the system starts, you are unable to boot up or go past the password due to a password. Try this:

To delete or disable the Power On password:
Shut down (Power down) the system and disconnect the power cord from the outlet
or the system unit.
Remove the chassis cover.
On the system board, remove the jumper on pins 1 and 2 of header E49 and place
only on pin 2.
Replace the chassis cover and reconnect the power cord.
- OR -
Remove the E49 jumper (green) next to the battery. Make note of whaere jumper was (pin 1-2 or 2-3).
Power on the computer, enter bios (Setup), F10 or F2 (I don't recall if they changed the key)
Disable 'Power On Password'
Switch off PC and replace the jumper.

Iam using HP Desktop D530 when i open some programmes but processor fan runs so fast and loud 2 gb ram in my pc and hard disk is 20 gb how can i reduce noice of fan ?


To reduce the fan noise, open the PC Case and clean the fan. Also, proper ventilation keeps the system cool and the fan runs at lower speed.

Hope this helps!

My cpu fan spins very fast than normal and makes a lot of noise. I use hp d530 cmt- 3.06GHz


Most fans are "temperature-sensitive" -- if it is sensed that your computer is close to over-heating, the fan will run at full speed, very noisily, to try to cool it.

So, shut it down, and disconnect the AC power.
Remove the side-panel.
Purchase a can of compressed-air.
Give the computer a "blow-job", to remove excess dust,
since the layer of dust is acting like a blanket,
keeping heat inside your computer.

Hp d530s problem restarts by itself (Windows XP Pro. I tried different hard drive, still same. The CPU and the power supply are very hot. The fan makes noise sometimes. What could be the problem? Thanks!


Scan the system for viruses. If no virus found check ur power options settings in control panel. Still u experience the same problem just uninstall anti-virus program from ur pc. This will fix ur problem mostly.

How do I unlock hp 530 laptop?


Inside of the computer you will see a small yellow(likely) button. Press and hold for about 5-7 seconds and then try, This is the CMOS reset button. If that does not work you can always remove the battery for a few seconds and that will work. This will also reset any bios settings you have saved to default.

HP D530 Will not start:


It can't be the RAM, it would be beeping if the RAM was not installed properly. If it was and they were bad, it would fail in Windows.

We've had numerous similar problems to yours with our D530's. Check the motherboard to see if any of the capacitors (round barrel shaped components) are swollen (round on top) or leaking. It is a known manufacturers defect and they were replacing those motherboards for free, unfortunately that program just ended.

If the capacitors are all flat on top, its probably the power supply. We've had four go bad in the past month. They sometimes smell like something is burning before they go bad. The D-530 model is unfortunately our most unreliable model ever, they are junk. Good luck.
