[Nandy_C]

Hi there,
Just a day before yesterday while watching movie, I got a blue screen error saying 'dumping memory' and and system crashed. Then when I again switched on my system, bios was loading but then the screen stucked when selecting any boot device. I was just left with a blank black screen. I tried to reinsert my RAM , switched the Jumper on the motherboard, and did reinsterted the CMOS battery to reset bios. But that too didn't helped . I cant understand where exactly the problem is. please help me out ...

My rig:

- Motherboard:: Intel DP55WB
- processor:: Core i5 1st generation
- RAM:: 1 x 2 GB Transcend, 1x 2GB Kingston , 1 x 4GB Kingston -- DDR3
- Graphics Card:: nVidia 9400GT 1GB
- 1.5 TB hard disk

Mixed ram modules do noty make a good computer, it could be that one module is faulty or not being read properly. It could also be a hdd problem like a bad sector.

I tried booting up using all RAM's individually , and as far as I diagnosed they were working fine. And took my hard drive out of the equation, I tried booting up using from my Pendrive having Ubuntu(Linux) in it. But no success
