    Computer switches on but does not boot up. The processor fan can be heard running fast. It will stay in this state for hours until you hold the power button down to force it to power down.

There are no drivers for CPUs.
The drivers are motherboard and device specific (the motherboard can be regarded as a device).
They will also depend on your operating system (which you should specify)

IBM 8123 not powering on the problem is the start up fan is running continuously.


Hello Dear,

If the Startup FAN is running, means the Power is going to your motherboard and other components. SMPS seems OK. You should check the display cable and CMOS Battery.
Just try to pull out the battery and Make the machien switch ON. (Don't forget to Check the display cable is connected or not).
If it is then means your CMOS battaery is faulty one.

WIth regards

When i start the system the fan runs in high speed and the system not booting, i have tried with replacing RAM, SMPS still then the problem persist


The fan you hear when the the computer start, is the power supply fan, the system not booting up mean you should check the cable which connect the monitor to the computer If the connection it proper then you should check the video card you can do this by try using another monitor or replace the video card because if its faulty the computer will never boot.

My ibm think centre wont boot i hear the fans come on but no boot


Hello

Without a laptop model number, we can only give you general advice.

Does the laptop beep when you turn it on? If it does, the number of beeps will indicate what is wrong.

If it does not beep, there may be a power issue - try removing the battery and use the AC Adapter only. Also, try swapping out the power adapter if you can.

IBM ThinkCentre M50 8189 power indicator is constantly blinking. There is no picture showing on the monitor.


This shows that the unit is dead right now. Do you hear any fans whirring? Do you hear the whine of the hard disk? If you do not hear any of these, you may not be getting power to your Motherboard. You can remove the cover to see if anything is running inside and then I can help you further

After i change the processor on the IBM thinkcentre M series the monitor green light just flicer all the time while the pc is on the cd rom green light just flicker on/off all the time the fans are running...


there are two reason for this problem. and the most probably is the first reason below.
1. your motherboard is not supporting the installed processor. although it powered up all the components and parts but the processor dont work at all.
2. even if your motherboard supports the processor and it works fine then there is problem with the VGA.

Finally to check the motherboard and processor whether they are working or not.
please remove RAMs from motherboard and start your computer and now if it gives the beeps sounds then motherboard and processor are working. and if you dint listen any beep sound then the installed processor is not being supported by motherboard.

Please dont forget to RATE my answer.

IBM ThinkCentre A51 PC Desktop won't boot motherboard power supply is good fan comes on. hard drive is spinning no video no audio or beeps


This could still possibly be a bad power supply, even if the fans and drives spin up. If you have a spare try hooking it up.

the list of things that can cause this are:

bad power supply
bad ram
IDE error (optical or hard drive problem)
bad card (modem, video card etc.)
bad processor
bad board

The first thing i would look for in this case is blown capacitors. Those are the little things on the board that look like little soup cans, usually with silver tops. If the tops of any of them are bulging or have junk leaking out of them, you have a bad board. If you are handy with a soldering iron you can try to replace them. Not sure if radio shack still sells caps, but they are easy to find on line. I have about an %80 success rate fixing boards in this way.

If the PS change doesn't work, then try it with different sticks of RAM, if you have more than one, pulling one at a time until it starts or you've tried it with all the ram. If not ram, disconnect the ide cables from the board, these are the wide ones usually connected to the HD's and optical drives. If it still doesnt start then pull all the cards. If it doesnt start then, try swapping processor and if still no joy a new board.

IBM THINKCENTRE A51 - WON'T BOOT


Simple dear, I think that you can see the power led and hdd led but it wont boot. Right. So switch the system and than open the cabinet and than remove the RAM , CLEAR THE DUST ON THE SLOT AND RAM. THAN REPLUG IT IN THE SAME WAY. PLEASE DO NOT INSERT IT FORCEFULLY BECAUSE IT WILL GO EASILY IF YOU ARE INSERTING IT IN RIGHT WAY. SO CHECK THE POSITON OF THE NOTCH ON BOTH THE RAM AND SLOT OK

AND THAN START THE SYSTEM. THIS MIGHT DEFINATELY SOLVE YOUR PROBLEM.
