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.

My dell gx 270 desktop shows alert! previous fan failer. Press F1 to continue and F2 to run setup utlity. How to solve it?


The fan failure alert on your Dell, is caused by the timings. There is no bios settings, for this. You need a new fan that runs at 1400rpm or more. This will solve the problem, also a clean install solves this problem. Best to buy a new quite fan, keep the 5pin header from the old fan copy the wire colour for the pins, make sure the fan is pwm. In the worst case, you will have to change fan, and overwrite harddrive and do a clean os install. This will fix problem, other methods, like fan speed software will redduce the fan speed cook your motherboard, but will not solve the fan failure alert. Also enter bios by pressing f2 and clear log error before you install new fan and os.

My girlfriends Hp Pavilion A305W powers on then automatically powers off after it show a brief error message but also says F1 for startup. Should i press F1 and continue diagnosis?


Most probably your system is not getting your BIOS settings from your mainboard due to CMOS battery failure.

Check your CMOS 3.0v battery & replace it. Then reconfigure your BIOS settings from the CMOS setup.

Hope it helps

At start send a message of cage fan failure push f1 to restart,what is failling


Inside your computer, there is a fan inside a "cage" (like you put a tiger in a cage) that has failed.
It is *NOT* the fan that is inside your power-supply.
It is *NOT* the fan that is on top of your CPU.

Replace the fan, or enter BIOS SETUP, and tell your motherboard to *NOT* "monitor" the speed of that fan.

I HAVE NOT LOOKED INSIDE MY COMPUTER, BUT THE FAN BEGAN MAKING A LOT OF NOISE A MONTH AGO. TODAY THERE WAS NO NOISE AND A MESSAGE CAME ON MY SCREEN SAYING "FAN FAILURE- PRESS F1 TO CONTINUE. MAY I USE...


Hi,

First, if the CPU fan is not spinning properly, you should NOT run the system. The fan needs to be replaced.

If the fan is running normally, you may boot by pressing F1.

Before replacing with a new fan, you can first try re-seating the plug for the fan in your computer. The fan's plug may have been bumped or loosed. Re-seat the plug located at J1F1 as shown in the picture below and be sure that it is properly connected.

Hope this helps.

CPU cooling fan


Hi...you can press the F2 key to enter setup...and scroll down until the fan is highlited...hit enter and then F10 to save and exit.This tells the computer its OK.
you should have plugged the fan in the same pin port the old fan was in. Usually only 1,.
If the new fan is not from dell..it may be faster and noiser..or it may be faulty..if you bought it locally you may try to return it.
The purpose of the fan of course is to remove the hot air from the CPU to keep it from overheating. If this fan does it it is most likely ok.
Hope this helps..
