I tried both Ubuntu 11.04,11.10 & 12.04. It frequently freezes at the purple screen (the screen before the 5-dot ubuntu screen) I wait for 10-15 mins and when I force re-boot, it ends up showing the Ubuntu BusyBox black screen with initramfs prompt. I checked many forums and many of them said to try this out----> 1.Boot using Ubuntu LiveUSB
2.In terminal,

sudo fdisk -l

I see sda7 as my linux partition ( I hv windows 7 also installed)

sudo fsck /dev/sda7

It shows many things.One of them I remeber is "Recovering journal"

and press ENTER for whatever questions asked during the process.Now when I go back ,remove liveUSB and boot Ubuntu normally,it works fine.But the same problem (freezing at the purple screen->force reboot->ends in BusyBox) comes up after 2 or 3 re-boots.

No problems when I install ubuntu 10.04 or 10.10. Then I thought it might be a problem with the kernal I m using.So I installed the kernal which ubuntu 10.10 uses, but it was of no use.The problem still remains.

Someone please help. Thanks in advance

You may have a hardware problem that does not manifest itself with the earlier releases. I would start by doing a memtest to ensure that my RAM is intact. Also I would check at least the SMART of my hard disk for reallocated/pending reallocation sectors. – Nicolay Doytchev May 6 '12 at 17:16
The memtest didnt show any problems. – Ajith May 6 '12 at 18:30
Now check the hard disk. – Nicolay Doytchev May 9 '12 at 18:17
