HI ker7758 ,

You may need to apply "Thermal paste/grease " to the CPU.

You can watch this video tutorial from Youtube:

There are different types of thermal grease. You don't have to buy the expensive ones. The cheapest on the market should be able to do the job.

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.

Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with 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 sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

HP P4SD, its running good with 4 gb RAM, P4 3.0ghz, and a couple sata hd. The problem is the fan output voltage, i havent been able to read the output chassis and cpu cooler pins voltage cause i can find...


"i can find my dmm?" did you mean CAN'T?
"its clearly off", what is off?
the fans are 3 pins,2 are power, one is RPM tachometer.
"it all works fine", so you can boot and run any OS, ?

"the voltage reads +12vdc", where, at fan or PSU?
the fans run off 12vdc, they are DC motors (from outside fan)
if the fan runs slow at 12vdc the the fan is bad or is a low RPM
fan, as some are, bigger fans run slow, for less noise.!

first is the CPU fan it must run full speed, if not the CPU will overheat in seconds and ALL CPU shut them selves (by there selves) this way. so CPU fan is first. what does it do... there....?

then BIOS screens. GOT BIOS UP? and running? with, ESC key pressed>.
let me guess your symptoms
1: PC dead. will not boot.
2: BIOS dead.
3: all fans DEAD,.
4: power switch works and all PSU voltages read right, (seems not)/?
5: if the PSU power wire reads right(DMM), matching the side sticker voltages, and the CPU is dead, the MOBO is dead, or CPU is toasted.


here is a modern PSU, sticker.
see 5 to 10 power lines, see them. all must read correctly
if a fan is dead, then its dead if 12vdc is present on the fan power pins.

You probably put more than a pin-head size drop of heat grease compound on CPU, thus "bleeding" over on the CPU, effectively overheating processor (very common). In any event, your problem is overheating -that's *the* place to look for now.

Try re-seating the RAM (memory sticks) with the system turned off. Clean out any dust from inside the PC, especially on the CPU fan.

When i on the system, the fan is not rolling, sometime when on and boot upto the the window evironment, its shut itself down. what could be the possible problem with them


Please Check CPU making any noise or not.

remove the CPU side door and check Fan is rotating on Processor if not it may not rotate due to heavy dust inside. ( clean it and refix it)

Check SMPS Fan is rotating or not..

If fans or not rotating Heat Builds up then computer shuts down itself.

If both fans are working...Just Open BIOS window by press DEL button continuosly while startup and wait for 2 to 3 minutes If the computer shuts down Itself in BIOS Window also then we can confirm issue with Hardware.

If Computer not shutting down in BIOS Window then issue with Operating System Boot files corrupted.

While Turn ON the system press F8 to enter in Safe Mode.

Open command prompt by clicking on

Start >. RUN >> type cmd >> then press enter.

now type chkdsk /f

now press Y

then reboot PC it fixes the Boot files error then your PC works perfectly.

If you still exp same issue let meknow..

Bootup problem


Your CPU is overheating.

Try and get into the BIOS and increase the fan speed & any aother fan on the system. Don't increase the temperature range, as this will damage the system.

You won't be able to sort out the software problem until the system is running within the hardware limits.

You can also run a office fan to help get the system to cool while making the changes in the BIOS.

Cpu fan noisy/chip fan fail error messages


pils,

Yes. This sounds like a fan issue. The noise often comes from bearings failing within the fan. Also, a failing bearing can make things harder on the motor as it brings the fan up to speed. This is likely the reason that you see increased warnings during the fan speed check while booting because it comes to speed more slowly as bearing wear increases.

I give this a 90% chance that your CPU fan is causing the issue. Since a decent CPU fan will cost you ~$20 online, it's not much out of your pocket if you happen to uncover another culprit.

I'll keep an eye on this post. Let me know how things go.
