System crashing at welcome screen

[arorah148]

Actually, I disassembled my dell latitude e4300 laptop and after assembling, it is now restating again and again at the welcome screen. I haven't changed any hardware bit I feel like I haven't connected everything properly. Also, if I insert the windows disc and try to install a new copy of Windows it is stuck at 0 per cent.

reinstall the RAM and HDD again, check the temperature inside BIOS (should be <70°C)

Why did you disassemble it?

Question from arorah148 : "System restarting on welcome screen"

Hi,

I recently disassembled my dell latitude e4300 (no hardware changed) and after assembling it, when I am turning it on it keeps on restarting at the welcome screen. Also, while I am trying to install a new copy of Windows it is stuck at 0 percent. I am using Windows 7.
