Hi There


My name is Percy and am new to this forum.


I have a Lenovo H410 Desktop Computer, It has been given to me as a gift from a friend.


The first time i used it was operating perfectly until i decided to setup a new operating system, it was running Windows 7 Starter and so I decided to upgrade to Windows 7 ultimate.


I went to the BIOS Setup screen which prompted me for a password. i then decided to clear the CMOS to remove the password, unfortunately to my disappointment the PC refused to startup, the fans are spinning, the power LED keeps on repeating a flashing sequence and there isn't any sign of the PC working. I decided to test for bad components, so i replaced the CPU with an identical CPU but still no luck, I replaced the RAM but still no luck, I replaced the PSU and still, so I disconnected everything except the PSU, RAM and CPU but still the same thing happens.


I need the computer fixed but now I have gradually ran out of ideas, I really need help solving this issue.


Thank you in Advance.


PS. System Specifications;


Board:         Lenovo L-IG41M3

CPU:           Intel Celeron

HDD:           320 GB


2GB Ramaxel RAM

What is the blink sequence?  Did you put the cmos flash jumper back on the original pins?  Does it beep at all or is there a speaker on the speaker pins to get any beep codes?
