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.

IBM ThinkCentre S51 Intel Pentium 4 PC Desktop won't boot up. The power light comes on for about a second and then goes off, over and over again. It does not stop unless I unplug it. The mouse's infrared...


Sounds like it's probably the power supply. The computer takes more power to boot up than to run, so if it can't get enough wattage it can't boot all the way up, and it will shut down and try again.

If you're comfortable opening your computer up, you can test the power supply connectors with a voltmeter or multimeter to verify. A new power supply is typically only $30 or $40.

Lenovo thinkcentre a51 reboots with several beeps


There is a system error in the system. Would be hard to determine cause of the error without viewing an error log. I recommend, using system restore and setting the pc back to a time it worked good. Otherwise, download a free registry error cleaner and registry optimizer called "glary utilities" from glaryutilities.org
Run the program to get all the bugs out of your pc

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.
