Power supply problem?

My computer randomly freezes from time to time. It seems like when I multitask or access my secondary hard drive it occurs most frequently. Also, when I try to put in two memory sticks in the computer it does not work, but it only works with one (both sticks work individually). I have the Silverstone Zeus 850W power supply and the specs in my sig. Could the power supply be the problem, if so is there any way I can check?
 
Finally got the system built, eh? Nice...

I'm guessing its your board or RAM. What settings did you try your RAM at (what voltage)?
 
stock voltage - 1.85 V
and i didnt change the timings, they are at 5-5-5-18.

yea i built it, but i had a couple of problems which are irritating me..
oh and btw.. i am unsure of how to make the memtest cd properly.. i tried twice, but i dont think they work.. i used magic iso and made it a bootable disk..
 
Just use Nero and burn a disc image.

Try giving the RAM more voltage. What mushkin sticks do you have again?

take your power supply to a local guru and have it checked surrest way i no and most computer shops do not charge,but see if they do.
 
is'nt most ddr2 memory suppose to run at 1.8v. memory timings should be 4-4-4-12

that is the memory i have...
i will try giving it more voltage.. but that doesnt explain why two sticks wont work, but only one will...

The only difference when you run two sticks vs one is power consumption. It takes more power to run two sticks, obviously. So, if the board isn't providing enough power, then of course, it won't run. So, its either the board or PSU's fault.

Actually, you're RAM isn't getting enough voltage if its set to 1.85v because it was designed to need more than that...

Increase your vDIMM (DRAM Voltage) to 2.0 and see if that helps. If not, try 2.1v. If its still not stable, up it to 2.2v. Once its stable, you can adjust the timings to 5-4-4-12.

JEDEC spec for DDR2-800 is 5-5-5-15 @ 1.8v. Thats the spec. While most manufacturers make their RAM bootable at those settings, most will need more voltage and manual timing adjustment to perform at the desired specs. RAM with EPP will "auto adjust" the timings for you, but I still believe you need to set the voltage... though I'm not sure.
 
Will your system pass an overnight run of Memtest86+ with no errors? I'd start there before you assume the memory is the issue....:cool:

Good luck -
 
alright thanks, i get the blue screen btw with two memory cards inserted..
right now i am trying with the voltage at 2.1v and gonna run it a few times to see if it freezes...
 
nope.. i tried 2.0/2.1/2.2 with the memory stick but it froze at least once in each voltage setting.. what should i do now?
 
Try more RAM voltage. Try 2.3v and see if that helps. The nForce boards sometimes have problems powering 4 sticks of RAM.
 
well with two sticks the computer does not start up....
with one stick it starts up fine..


could there be possibly two problems? maybe the freezing is unrelated to the fact that my computer does not start up with two sticks in...

Its possible. Can you get new RAM to test in your board? Borrow some from a friend or something.
 
i will try.. although i doubt anyone will have any..

but if i run memtest the errors should show up right?
 
i dont know how to create a bootable disk... i have tried like four times and wasted all those cds.. can anyone tell me a site that explains it, or can someone help me out..
 
What are you using to burn the ISO image? In Nero 6, the option is "Burn Image."
