A2 and B2 is yellow... and the manual said that i must put in the yellow slot first then black....

Argh Yes that would be right then

So to quote again:

You have now not removed the single black slot Ram
But you have removed the two Yellow slot Rams (and then put one of these in the other black slot. (making dual channel)

Although I had no idea if Black comes before Yellow. At least I stated to remove the extra (non dual channel) Ram

Is still correct, except as per the manual A1 and B1 must be black, of which wasn't stated, therefore I could not know.

Anyway yes, as I've stated match the colors
Then you stated black comes first

Done.

Now, any restarts?

nope like i said on post 2#1 yellow come first....


nothing on restarts but one time frezee but i think it's the windows vista stuff.....

looking forward to windows 7

You know I'm still confused here
Wouldn't A1 and B1 be the first place to put Ram?

Anyway one of us is going to become unfolded in this, and I still haven't read the manual

Don't forget to change Kernal memory dump to small memory dump in startup & recovery options per Kimsland link in case you get another BSOD. Otherwise no minidump!

Ok....i think the problem solve now. i just get my system back after repair. and they conclude it's a PSU problem...
they change my PSU and it's working great...
