Re: cpu fan lo.
Replace the fan ASAP.
Looks like when the system overheated your Windows registry got corrupted. It is possible that someone who knows what they are doing can get a copy of your registry from a restore point and replace the corrupted files using a Linux live CD or BART PE CD.

Really need more information, but my guess is dirty fan. If fan is blocked by dust, it may make noise and may run at high speed all the time because the CPU is overheating. If CPU gets hot enough, the laptop will shut itself down without warning. If dust is the problem, get some canned air. Before blowing into the air vents, try to spot where the CPU fan is and gently insert a toothpick to block the fan and prevent it from turning. A long blast of compressed air can spin the fan too fast and burn out its delicate bearings. Blow air from underneath and also from the side vent until air blows clear. In some bad cases of dust, the bottom or top cover must be removed to get it all out.
On motherboard. Please, make sure all fans are connected into motherboard. Some fans can't plug in into the board at all. So, you can ignore those fans. When you go to Bios to check thermal condition, if a fan is not plug in, you can see 0 degree. 0 degree dosen't cause the shutdown problem. (That's why you can ignore) Then check which fans are causing problem, first. (If you did and found the problem, go next.) Replace fans AND clean those dust! If the problem remains, then replace its case to steel one.
Well, usually a lifetime of CPU fan is pretty longer than others.
Just in case, one more thing, if the thermal condition is OK, then the shutdown problem is caused by something ales!
when the fan stops 2 things are happening 1 the bios sences no rpm speed from the fan or the processor heats up to quickly and the safety in the bios will shut it down. try moving the fan connector to the case fan connector then go into the bios and change the fan settings. this is only a temp fix the fan stopping tells me that the onboard cpu fan regulator is going out and this is a precurser to more problems to the board going out. also just to be certin check the power supply 4 years ago i came across this in a gateway it was weird.
When the computer crashes.... does it just shut off with NO WARNING?
Is your PC BEEPER SPEAKER connected and if so, does it make a very soft alarm (like an ambulance) before it shuts off.
Do you know how to check CPU temp in BIOS? Next time it happens turn the PC back on and check the CPU TEMP in BIOS.
What I am getting at here is you may have a CPU OVERTEMP condition occuring. That is a very beefy card and will generate alot of heat, and even though it will have a fan and manifold mounted to port the hot air out, you will still see an increase in TEMP inside your case.
If this is the problem, you may want to add another CASE FAN (cheap option) or if you are really keen, get an aftermarket CPU COOLER and heatsink (Recommended for any High End build).
Based on your symptoms (and without detailed information) this would be my main suspect at the moment.
Windows restarts without warning Cause: This issue could be caused by any of the below possibilities.
Software issue or error. Hardware issue or error. Heat related issue. Computer virus. Issue with operating system. Answer: Software issue or error Errors generated by software programs can cause a computer to reboot unexpectedly or without warning. If you are running Windows XP see the below section "For Windows XP users" before continuing.
If you are not running Windows XP or following the below steps still cause your computer to reboot without warning. Boot your computer into Safe Mode, and let the computer run in Safe Mode.
If the computer is still rebooting in Safe Mode the issue is likely not software related but something else, skip to the next section. If the computer is not rebooting in Safe Mode it is likely you have software related issue. We would recommend you run through the basic troubleshooting section for your operating system. For Windows XP users
Windows XP is designed to automatically reboot each time an error occurs such as a BSoD. Although this may be nice for errors that do not occur often, users who have a re-occurring error may wish to identify the error to troubleshoot it. Below are the steps on how this feature can be disabled and enabled in Windows XP.
From the desktop right-click on My Computer. Click the Properties option. In the System Properties window click the Advanced tab. In Advanced click the Settings button under Startup and Recovery. In the Startup and Recovery window uncheck the Automatically restart check box. Click Ok. Now if the computer generates and error it should not automatically restart and enable you to display any errors your computer may be experiencing. Hardware issue or error Any failing hardware component in your computer could cause your computer to unexpectedly generate an error and/or reboot without warning. If you have recently attempted to add a new hardware device, remove that device to make sure it is not causing your issues.
Make sure you are not encountering any hardware conflicts by viewing Device Manager for errors.
New drivers can also cause this issue, if you have recently performed any hardware driver updates you may wish to try an earlier version of the drivers.
If you have updated drivers and removed any hardware that could be causing this issue and continue to experience random reboots, it's possible that the memory is bad in the computer.
Finally, hardware devices that are not installed properly in the computer can also cause random reboots. Make sure all the cables and expansion cards are connected properly to the computer. The best way to determine this is to disconnect and reconnect all cables and expansion cards. Computer virus Computer viruses such as the blaster virus are written to reboot your computer without warning. Usually these viruses will make the computer reboot ever 5, 10, 15 or 30 minutes after the computer has booted.
If you believe your computer may be infected with a virus or are uncertain if your computer is infected with a virus make sure your virus scanner definitions are up to date.
Heat related issue Many computer today are designed to turn off or automatically reboot if the computer, processor, or other device in your computer gets to hot. If you have heard any abnormal noises coming from your computer recently such as a high squealing this could indicate a fan may be failing in your computer.
You can first start by verifying the fan on the power supply is working by examining the back of the computer and seeing if the fan is moving and moving smoothly. For all other fans in the computer you will need to either open the computer and make sure the fan are working (processor fan and case fan) and/or if your BIOS monitors the RPM of the fans enter BIOS and make sure the BIOS does not report any errors.
Users may also be able to determine how hot their computer is by onboard thermal sensors, if your computer comes equipped with these sensors make sure your CPU is not running to hot. Issue with operating system If after following each of the above recommendations your computer still continues to reboot it is likely that you are experiencing a Microsoft Windows operating system related issue that cannot be explained. To help make sure this is the case please try the below steps.
Reboot the computer and enter CMOS setup as the computer is booting. After you have loaded the computer in CMOS setup let the computer sit. If the computer does not reboot while letting the computer sit in CMOS it is likely that you are in fact experiencing an issue with Microsoft Windows and it is recommend that if you have followed all of the above recommendations that you reinstall your version of Microsoft Windows.
the fan must be the correct fan
i guess you meant the CPU fan, ? desktops can have 2 or 3 fans.
the fan has 3 wires, in many cases, the 3rd wire is a RPM tachometer that if not correct the PC can not read RPM
if RPM reads 0 the PC will be very upset. and do that.
my guess you bought the wrong fan, and is super easy to do
giving the many fans
on some PCs the BIOS monitors the fan RPM and heat sink temperatures, or both, and tells yous fan bad for either failing
on my PC here, now, I can go in to bios and see both live sensors
RPM and Temperature. this allows for easier diagnosis
i dont think your PC has that page in BIOS to do monitors for trouble shooting, in fact mine has 3 fans all 3 are monitored, now.
high end PC .
this older desktop , only the m7200 pages are there. at hp.
so cant look at the fan nor BIOS.
i use a windows program that lets me watch the fan speeds
and all CPU and GPU core temperatures. (ask) its free.
the troubleshooting guide at HP stops short at this problem
says get it fixed. so you want to fix it your self sure.
so talk to one of the top, CPU/HEATSINK/FAN makers
and buy this from them.
if the fan spins fast and RPM is 0 wrong fant
if the fan spins fast and RPM is ok, then the BIOS dont like the CPU temperature... this has 3 causes.
fan dead. or slow. or wrong fan installed
heat sink fins packed in lint as all do ever year.
heat sink thermal bond compound failure, common.
