When we start WINDOWS XP it shows strip moving from left to RIGHT below the XP logo and after that we get all light BLINK at same time when we start the pc.

How ever in my case the problem is that it get hang during this process and the strip stops moving.
However somethimes after  a lot of chkdsk attempts from "SafeMode Command Prompt" some times it get start but it depends and happen randomly.

I have done FOLLOWING thing to check the fault
1. Tested other Ram and also my RAM on other computer (They are fine)
2. Checked HDD with CHKDSK on same com and on other computer (No bad sector)
3. Replaeedd mother board battery (In case of battery problem)
4. Removed LAN and Modem cards from motherboard in case of there failure or problem

So could any buddy please suggest something about.
1. What should i do
2. What could be the possible cause of this
3. What things happen behind the sccreen when that logo is displayed

I hope i will get valuable suggestions ...........................Thanking You

Check your video card is seat properly, can you tell me what how this happened ? also try cleaning out your case when you check the video card .. also what protections do you have on this machine? have you done the scans in safe mode?

try chckdsk /f if you haven't already.DLoad and run the diagnostics from the HDD manuf. site...they are a bit more thorough than chkdsk in spotting DISK errors...I agree with patio...not that it matters...LOL!

Anyway...when the sysytem hangs like that...especially while trying to boot into Windows...it's usually a good sign of a damaged or corrupt boot sector.

Follow patio's advice...then get back to us with the particulars...okay?
