thaks for the replt i bought the machine i dint build it, and is that a major problem and how can i fix this
It could possibly mean that the CPU Fan is slowing down or throttling. Did you build this computer and if so, did you apply the thermal paste correctly?

i bought pc of a mate it. the pc has been working fine without any problems but two days ago i put it on it kept on restarting when loading on desktop so i tried loading in to safe mode it wouldnt let me on safe mode. its doesnt give any error message when powering it up
Perhaps it would help if you explained how this came about. Did you buy a PC off somebody and it's never worked? Has it been running fine and it doesn't work now? Are you booting in safe mode because it won't start normally? What appears on the display from the moment you start the PC?
Edit: I got a copy of the manual. There are quite a few different models of the P5Q plus the different OS too. You should go into the BIOS, Power Tab, Hardware Monitor. Check the CPU fan speed and what you have selected for the Q-Fan Control and Profile items. Check the chassis fan details too. Any warnings?
If it's not something simple, I don't see what you can do yourself. A repair shop or someone who dabbles in repair may have spare fans they can try. I doubt you have any!

Hi iv done that and its been ok as of yet, but today in bios mode the power fan speed below 600 was showing in red ??
That indicates it's not seeing the CPU fan running. I'm assuming you haven't been playing around with the fan because as I said before, if it is connected incorrectly you will get an error.
I suggest you enable CPU Q-Fan Control and initially set the Profile to Turbo. See if fan speed appears. If so Save/Exit and see if it boots normally.
If it runs you could then try Standard or Silent profiles.
Edit: If enabling the Q-Fan Control does not work, disable it like you originally had. The fan should run at full speed. Go to the CPU Fan Speed item and change it to "Ignore". Apparently the BIOS ignores any speed below 800rpm and thinks the fan is disconnected or not running. In changing to "Ignore" you are losing what should be a useful safety interlock, but it's not much use if it stops the PC running when there really is not an issue. You still have CPU high temperature protection.
If the PC now boots up, I suggest you monitor the CPU continuously for a few days with a utility in Windows. There should be an ASUS utility for that PC Probe II, otherwise Speedfan, HWmonitor or similar. Could you post back the CPU fan speed (if readable) and temperature.
In the Boot setup is a curious item "Wait for 'F1" if Error". It does not say what that actually does. Anyone?
If this cures the startup issue, then what caused it to happen out of the blue? If you were using Q-Fan Control it could be that the change in room temperature with the change in season slowed the CPU fan enough to be below 800rpm. However, you were not so it should have been running at full speed (whatever that is).
