How do I access the BIOS settings for the P5LP-LE motherboard. The startup key says to press F1, but pressing F1 does nothing.


The instructions say:
"Hold down the F1 key during the startup process and enter BIOS setup to re-enter/reset any custom BIOS settings." I would also try hitting the F1 key multiple times from the very turn on of the computer because the key may have to register at some point after turning on.

Try clearing the CMOS settings as explained on this page, it should clear out any passwords and will set the BIOS settings back to factory settings.

As for "The CPU fan runs normally on boot, but as soon as the Windows flash screen comes up, the CPU fan slows way down."
This is quite normal. On start-up the temperature of the CPU is not being read, when the flash screen comes up just happens to be the same time that the computer recognizes that the CPU is cold and doesn't need to be cooled.

On the "Then the installation program starts running and the CPU Fan speed starts fluctuating wildly from slow to extremely fast."
This could be normal as when files are read from a DVD the CPU doesn't work hard, but when it unpacks the files or does calculations it does work hard. Or it could be that the thermal paste between the CPU and the heat sink is not correct. Either dry , not making contact, or even too much. If the heat is not being transferred that would also explain the shut-down.

Fan blade cracked


Replace it. Warranty if still in time and not due to bad installation or error. New purchase otherwise. Do not run the fan with a cracked blade or the computer without a fan.

Need installation instruction on CPU Fan & heatsink


i recommend using artic silver thermal paste. i just put a small amount on the cpu and use a credit card to make it as smooth as possible..the main thing is to make sure there are no bubbles in it..remove the plastic protective cover from the bottom of the heat sink and make sure there is no pre existing thermal paste already on there if so remove it gently until clean with a cloth and rubbing alcohol ..as far as exhaust most fans are designed to get heat away from components and not to push the heat into the components there should be arrows somewhere on the fan showing fan rotation and airflow hope this helped...

Which way does the rear fan go in a compaq computer tower


The proper installation of a CPU fan is often the subject of debate. Though there are conflicting theories as to which direction the CPU fan should face, there are methods to ascertain which CPU fan installation best suits your needs. The determining factors of your CPU fan installation direction include the manufacturer specifications, your case design and the specific design of your heat sink
Horizontal Installation
  • The installation of a CPU fan horizontally to the plane of the motherboard is the most common installation orientation there is. Your options when installing your CPU fan are to blow cool air onto the heat sink or to pull cool air through the heat sink from the motherboard. Horizontal installations show negligible advantages in either installation direction. The differences in temperature usually vary by only 1 or 2 degrees Celsius. The main point to consider when installing a horizontal CPU fan is the location of the rear exhaust fan on the case. If the rear exhaust fan on the case is parallel to the processor, it is advantageous to have the fan pull cool air from the motherboard and push it out above the heat sink. This is because the case fan will quickly draw that hot air away from the CPU and out of the case, allowing for quick cooling.

Vertical Installation
  • Vertical, or tower, heat sinks rise high enough off the motherboard to allow for a fan to be installed perpendicular to the plane of the motherboard. This allows for cooling to go from the front to the back of the case, as opposed to going from the bottom to the top. Optimal installations for vertical heat sinks are blowing toward either the back or the top of the case. If there is no exhaust fan in the top face of your computer's case, it is more effective to orient your fan on your vertical heat sink so that it blows toward the rear exhaust fan of the case. If there is an exhaust fan on the top face of your computer case, it is almost always more effective to mount your CPU fan so that it blows air up toward the top of your case. The reasoning behind this is that hot air rises and will more naturally flow off the top of your case. Also, top-mounted fans are usually larger and allow for faster airflow out of the case.

Manufacturer Recommendations
  • It is often the case with nonstock heat sinks that the manufacturer has designed the heat sink's fan to be mounted in a limited number of orientations. This is usually evidenced by limited mounting notches on the heat sink itself. Most aftermarket heat sinks use technologies such as heat pipes that have specific cooling needs to operate appropriately. Because of this, it is important that in any CPU fan installation you follow the manufacturer's installation instructions.

My toshiba laptop turn off during installation


When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

Hello there,
Here is the link that will show your motherboards CPU support. just click the link.

CPU Installation Procedures for Socket AM2
1. Please turn off the power and unplug the power cord before installing the CPU.
2. Pull the lever sideways away from the socket. Make sure to raise the lever up to a 90-degree angle.
3. Look for the gold arrow on the CPU. The CPU can only fit in the correct orientation. Lower the CPU down onto the socket.

4. If the CPU is correctly installed, the pins should be completely embedded into the socket and can not be seen. Please note that any violation of the correct installation procedures may cause permanent damages to your mainboard.
5. Press the CPU down firmly into the socket and close the lever. As the CPU is likely to move while the lever is being closed, always close the lever with your fingers pressing tightly on top of the CPU to make sure the CPU is properly and completely embedded into the socket.

Installing the CPU Cooler
1. Position the cooling set onto the retention mechanism. Hook one end of the clip to hook first.
2. Then press down the other end of the clip to fasten the cooling set on the top of the retention mechanism. Locate the Fix Lever and lift up it.
3. Fasten down the lever.
4. Attach the CPU Fan cable to the CPU fan connector on the mainboard.

Installation of fan


Not knowing if you have ever taken one apart, start by laying the screen all the way back(flat) and then remove strip with power button. you have to start on the right side where there is a small notch. then remove 4 screws for keyboard. DON'T DROP THEM INSIDE CASE! remove 1 screw for shield. Then 4 screws hold down heat sink/fan assy. remember to disconnect power lead for fan. Installation is reverse. Be sure to use thermal grease between cpu and heat sink assy.
