Ok well my pc is refusing to start at all. I get no post but I do get power to the PC.

I think it maybe the motherboard (Asus P5N-E SLI) but the place I bought it for thinks it maybe the ram (Cruicial Ballistix) :confused:

Here are the tests I have done to date:

Just CPU + Mobo = 1 long beep followed by 2 short beeps
Both Memory sticks tested in all 4 slots = continous beep
Both pairs of sticks at the same time in yellow slot = Continouse beep
Both pairs of sticks at the same time in black slot = No beep
CPU+1 Mem Sick + GPU = Continous beep\

So that to me seems to indicate that the yellow slots on the mobo are broken? But I have tried starting the pc with the memory in the black slots and still it wonn't post??

I am thus completely confused wheather the mobo or the ram is defective, is there any other things I can do to test this? Oh and I don't have any spare parts to test with.
 
AwardBIOS Beep Codes
1 short: System boots successfully
2 short: CMOS setting error
1 long 1 short: DRAM or M/B error
1 long 2 short: Monitor or display card error
1 long 3 short: Keyboard error
1 long 9 short: BIOS ROM error
Continuous long beeps: DRAM error
Continuous short beeps: Power error
 
Ballistix is very fussy about voltage, the default 1.8V is not enough for some kits so maybe you need to boot it up with different ram then up the voltage before putting the ballistix back in.

although having said that I had the same 4 sticks ballistix PC5300 in my pevious P5N-E no problem.
 
Well I have had this system running for around a year with no problems. Then it suddenly had issues posting when I powered it up. But if I switched it off it would boot fine but would have lost the Overclock settings in BIOS, but if I loaded the settings again it worked fine. Then one day it refused to post at all. So when I start the pc all I have is a blank screen. And unfortunetly I do not have any other DDR2 ram to test with.

And from those codes it could also be the Monitor or GPU? As it says:

1 long 2 short: Monitor or display card error

EDIT: I can actually test the graphics card though so will try and do that tonight.

Which is what I get when only the CPU and Mobo are connected?

ram is a fickle mistress, i knocked my pc slightly and it did the same thing, if all else fails play with the ram.

also set the bios to default settings and work from there.

edit:forgot to say i would doubt very much it is a gpu problem, if you look at the errors beeps i posted you can almost use that to work out that it is the ram.
 
Well I have installed it and unistalled the ram several times so can't think what else I can do. I can't change any of the BIOS settings as I get a black screen, no boot sequance at all, thus my idea it might be the GPU. Its not a problem to test the gpu as my brother has a ATI 1900 GPU I can plug in. At least that definetly rules it out. Only problem if it is the GPU is I have taken the heatsink/fan off to watercooling sigh.

1) No surprise there - will check for presence of a graphics card before testing the RAM.
2) Faulty RAM
3) Faulty RAM
4) Fill the yellow slots first.
5) Faulty RAM

See a pattern?
