HELP - Unable to boot up, Possibly due to RAM?

Hi Guys,

Any help is appreciated with this!

Machine slowly gets to the loading windows screen, but then stays black.
Swapped back to old RAM, works fine.

My MOBO: Ecs MCP73VT-PM LGA775 DDR2 Motherboard
NEW RAM: Crucial 2Gb 240 - PIN UNBUFF DIMM 256X64DDR2 PC2 - 5300 (x2)
OLD RAM: MT8HTF12864AY 1GB

Can someone please point out where I have gone wrong with this?


UPDATE: So I tried the NEW RAM seperately. One stick lets me boot up into windows, but the other doesn't. Does this mean it is a faulty stick I guess then?

  1. Did you "reset BIOS to defaults" after installing new RAM ?

    IS RAM then at correct speed and timings ?

    Does you MoBo support the type and speed of the new RAM ?

    Is RAM in correct slots ?

    Does new RAM pass memtest86+ ?

    Is the RAM in your post the new RAM or the old RAM ?
  2. Try sticking the new ram to another ddr slot, try both slot.

    IS RAM then at correct speed and timings ? I know it is one, what is the other?
    They are both 667 Mhz

    Does you MoBo support the type and speed of the new RAM ? - I thought so, I went by the DDR2 and the Mhz (New to this building your own thing so I thought that was all I needed to check)

    Is RAM in correct slots ? Yes/

    Does new RAM pass memtest86+ ? - Please advise how to check this?

    Is the RAM in your post the new RAM or the old RAM ?
    Updated original post.

    Thank you!

    Thanks, this prompted me to try each RAM seperately. One has now let me load into Windows, the other did not. I'm thinking I need to send that back as faulty?
  5. Have you tried sticking that the 'suspected bad ram' on the slot where the good ram sits? If you have, then you have 1 good ram and 1 bad ram

    Yeah, both were tried in slot 1. Looks like I have to send this back off then -.-

    You need to send the pair back and get a new pair if it is faulty...... but 1st make sure that it's the stick that is bad and not the socket....try both sticks in primary socket and secondary sockets. Use your MoBo manual to see what goes where.....even among brands . On most of my Asus Boards it was 2nd and 4th from CPU..... on my newest build, it was 1st and third
