Do you mind telling the brand of video card or the exact model of motherboard please, so that we can help you?

is this new motherboard the EXACT same as the old one

if not

i would not really expect it to boot without problems

as above

the EXACT specs are needed

but really reinstalling after such a MAJOR change is the best option


seeing as this is the OLD legacy support RHEL5 ( rhel5.11 is the current)
you DO have the required support contracts all paid for and up to date

reinstall and move the data over from the back ups you made


but as to fixing

WHAT is in the logs ???

without the boot.0.log 's error message there is really nothing that can be done other than making GUESSES
/var/log/boot.0.log

i'm using integrated graphics. Its an ASUS motherboard . and the cpu is Pentium D(3GHz).
This new motherboard is totally different from the old(defective) one.

thank you

This new motherboard is totally different from the old(defective) one.

thank you

Again, could you please either give the brand of video card or the model number of motherboard!

Yes, here it is with pic :

motherboard is P5GD2-TVM/S ( of ASUS).

I agree with John VV, that the change of motherboards probably would cause problems like this. Reinstalling would probably be the best way, because otherwise it would be a hassle to change all the many config files, etc.

so AGAIN what is this CHIP
there is no way to tell from that tiny thumbnail

Re-installation is the last option for me. As i have some applications which i cannot afford to loose. Now i can't do anything as the os just hang after the earlier specified error messages...

Thank you.

I hope this help.

Thank you

John, it is an Intel i915 Northbridge. I thought it could need nomodeset, but that's a lot more common with nVidia. Although, the OP could try appending "nomodeset" to the kernel command line in grub and see what happens.
