Screen not displaying. and fun starts and stops, remains stand by when restarted the fun runs and stops stand by.


hello there,

I got the same problem but it came gradually...

In fact for a full month when I first boot the computer, the fans runs, no extra beeps, the light blinked correctly but no bios at the screeen. I remarked also that the fans run full speed doing a lot of noise. Then I stopped the computer and wait 2 minutes and then it always works correclty at the second boot with the bios screen appearing. Also, the fan calm down after 1 second with less noise. So when I start the computer and hear that the fan calm down with less noise after 1 second, I know that the computer will boot correctly. That happens always at the second try after waiting 2 minutes. But since yesterday, the fans never calm down and the noise still remains high with no Bios at the screen. I'm suspecting the Power Supply...

i hope my i dea can help you.

By the sounds of it, you are having an issue with the motherboard. I had a similar issue once and this helped:

-Unplug computer from power source
-Hold the power button for 60 seconds
-Open the case and remove the video card and RAM. Then remove the battery from the motherboard (the small disc type battery)
-Put the battery back in, and reseat the RAM and video card.
-Plug it in and start it up

If this doesn't help, you can also try replacing the battery on the motherboard. Of course, if/when you get to desktop, be sure to update all the important drivers (display, video, bios, etc).

Ceiling fan stuck on high


The Inteli-Touch system does have a slight learning curve.

How the system works is. You turn the power switch on, and leave it on, all the time. To set fan speed, you press and HOLD the fan button and it will go. . beeeep. beeeeeeeeep. beeeeeeeeeeeeeep. beeeeeeeeeeeeeeeeeeeeep beeeeeeeeeeeeeeeeeeeeeeeeeeeeep beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep (higher pitched) when you reach your desired speed you let go of the fan button and it stays on that speed. So if you want to go to speed 4 you wait for the fourth beep and let the button go. To turn off the fan, press and release the fan button, to turn it back on to speed 4, press and release again. It has a memory. If you want to go to a higher speed while on speed 4 (or any other speed) just press and hold. To slow down the fan, you must turn the fan off by pressing and releasing the fan button, then pressing and holding until you get to the speed your desire.


The instructions which came with the fan should explain the rest. After you get used to using the IT control system, you will love it. I do. I have two Casablanca IT Victorian II fans in my living room. They are featured in this video. http://www.youtube.com/watch?v=2pv55wZqohs

After power on Fans are running but no Videosignal, no bios startup.


Could be 3 things Memory or CPU or Powersupply. are you getting any beeps if so how many, how long. try taking all the memory out and powering up see if it beeps if so try to put one stick of memory in at a time and see if it will boot. if you get no beeps with memory out check powersupply some PS's have a red switch on back for current input. switch back and fourth about 20 times uning a pen and set it to the right current for you location. put ram back in see if it will boot if not its trial and error of the PS and the CPU replacement and it still could be the RAM giving false readings. yea i know sounds like a ball of fun.

What lights should be on when the computer boot up. sony vgc-rb34g desktop . power on fans run at high speed keyboard lights flash hard disk light flashes mouse light on no beeps or codes no display on...


You may possibly have a bad video card and a bad circuit on your motherboard. I would have the motherboard replaced. Some motherboards come with video cards, so once it is replaced, you may alerady have a new one with the motherboad part. If you not versed in doing this, you may want to get a professional to do so.

Hunter fan with remote control was 3 speed, now only 2 speed


It sounds like fan motor is okay. There are two motor windings -- one low speed, one medium speed. Low winding gives you low speed, medium winding gives you medium speed, both windings give you high speed -- so I would say if you get high speed, both windings are good.

The remote (the hand held transmitter) controls the speed by raising and lowering the frequency of the current which is 60 cycle coming to the fan ceiling box. If the fan speed -selector switch (usually a pull switch) is set to high, when the remote (transmitter) signals the receiver to change speeds, the frequency of the current is changed by the receiver (the receiver is usually in the fan housing).

Sounds like you'll need to replace the remote system -- these come in sets, both transmitter and receiver, and cost about $30. If you're not experienced with wiring fans, you should get an electrician to do the job.

I cant get the fans to turn on!!!!!!!!!!!


Call up the 'Integration Menu" - the fans can be switched between 'auto' and 'full speed'.

To do this switch the display into standby. If the standby light flashes 4 times it is indicating a fault in the Thermal Sensor Assembly which will explain why your fans aren't working. With the display in standby press the menu button and within 3 seconds press the power button. The display will turn on with the integration menu. Select the option tab and scroll down until you see 'fan control' - press 'set' to toggle between 'auto' and 'max'. When you select 'max' the fans will run at full speed within a few seconds. The fans are a bit noisey at full speed so you may want to look into replacing the sensor eventually.

It is likely your power supply is failing. When you press your power button a signal goes through the motherboard to the power supply, then the PS comes on. I would try a replacement power supply first, you can get a used one for less than $20.

Pc Seems to be dead wont load bios post moust doesnt work or keyboard or monitor


I have the same problem, the CPU fan spins, keyboard lights blink, no start up screen, or bios.
But, when I push a few times on the pc reset button, then the CPU fan is becoming still, the keyboard light are out and I can start the computer again in a normal way.
Can this one be a temporally solution for you too? Do you have any suggestion about?
I guess it can be an electricity dysfunction of a wrong fixed cable.

Monitor doesnt switch on


Can you try another monitor?
Since you did try another video card (AGP). I posted (In you're other post), you have to make a bios adjustment under Advanced menu. Once you're P4SP-MX bios is set to boot to the AGP or set to Enable. The bios will no longer try to load the on-board VGA card. I am not being picky about the statement I am going to make ( so don't be offended). Monitor's only receive signal. They do not send signal to PC, just receive. The odds of two video cards not working is high. You did mention you have not heard P.O.S.T (A single beep), which is a test of the motherboard. There could be a loose connection in you're PC. I would remove the memory first. Clean the contacts with alcohol on a cotton swab & blow out the memory slots with canned air (allow time to dry). Than firmely reseat the memory. I would than re-check all data & power connectors within the PC, making sure all are securley connected. With respect to the AGP card, I would do the same. Remove, clean & reseat. Most older AGP's require additional power. Some use a power cable that is also used to power a floppy drive & others use a 4 pin molex (see link),
http://pinouts.ru/connector/4_pin_Molex_power_connector.shtml.
When you are in the bios & within the Advanced menu you may also need to set the bios to read you're AGP card to the correct speed. (EX: 1x,2x,4x). Page 2-19 in you're manual. Once all these checks & cleaning have been completed, try again. Boot the PC and hopefully you will see display on you're monitor.

Post here. Let me know how thing go. Don't assume anything, check all.
Luck!
Mike
