Question about HP Pavilion 515n (DC471A#ABA) PC Desktop
Some people, when their computer reaches the point that it can't run the programs it once used to, decide to toss their machine and invest in a new one. Others squeak out some extra life by overclocking their processors. While this is ideally done with hardware, for pre-built HP computers you will have to use a software option. With this minor exception, the process is still a breeze.
Download and install CPU overclocking software, such as ClockGen, SetFSB or SysTool (see Below). http://files.extremeoverclocking.com/file.php?f=189 http://www.softpedia.com/get/System/Benchmarks/SetFSB.shtml http://www.techpowerup.com/systool/ While all these programs more or less work the same, for this guide we will be working with ClockGen. Boot the CPU overclocking software. Do not be alarmed if your computer momentarily slows down, as the software is reading your CPU's clock speeds. Click "PLL Control" or the equivalent in your overclocking software. This will show you several sliders for your front-side bus (FSB) and, in many cases, your PCI cards. Adjust the FSB slider. Be sure to do this slowly, as the processor will likely fail if there is a sudden speed change. For best results, use the arrows to slowly adjust the settings by one-to-two megahertz at a time. Click "Apply" frequently to set the speeds. Hope this helps.

SOURCE: HP pavilion 515n runs real slow
you may consider follow:
1) you need to make sure your system slower than before the reason that should be excepted some windows system file damage or never clean disk fragile files and clean temp files
2) your PC max ram size is 1G (two sockets), now you have 256M+512M two ram sticks, so you can replace the 256M with 512M ram stick, you should make sure new ram should be same model as your original one.( your ram model is PC2100)
is this helpful or fixed your slower running?

SOURCE: loud fan noise
have one very similar, they only have a fan in
the power supply, and a small, small fan on the CPU. If it's the fan in
the power supply making the noise, some people would say replace the
whole unit, some would say replace the fan. I would replace the fan,
but if you don't want to take the risk of getting electrocuted, that's
probably a great idea. A power supply can be found somewhat cheaply,
but one that fits those cases might not be quite as easy.

Hi, most motherboards that I have fixed etc... have used the 3.0V CR1620 Button Cell Battery which is easily available and cheap!

You don't need a wiring diagram. Just pay close attention to where things are plugged in while the old power supply is still in the computer once you remove the case. There are only a few connections and some of them will only fit in the correct slot on the motherboard. For example, the main power to the motherboard will be the largest connector, then you will have a connector to the hard drive, the dvd/cd drive, etc. What you could do it take a piece of masking tape and and fine tip marking pen such as a Sharpie and write where that wire is being plugged into the motherboard. Then when you remove it and put the new power supply in, just refer to where the plugins go based on what you marked on the old plugins. There will also be some plugins that go nowhere. They are there for future expansions and upgrades that you might do.

Message was "press F2 to continue". This happens when there are errors in the boot up process like:
CMOS settings incorrrect
First to replace should be the CMOS battery inside the computer.
