Have your system worked before and then become this way, or have it never worked?

my system had been working great for over about a week. this is a brand new system.

 

i flashed the bios to official 9/14 about a week ago.

 

since then i haven't flashed it with a new bios.

 

i applied these settings as were implied by DocGiggs in another thread i posted earlier:

-----------------------------------------------------------------------------------

First off, stop using the 9x multipler. It's broke. Don't even think about it.

 

Second, this board has problems with 2 sticks of 512. Not for everyone, but for enough people that you can now be considered one of the official club member. It's a bummer but it is the case. You SHOULD be able to hit 250 x8 or x10 depending on how you set your timings.

 

After tons of playing around... here's the most stable I can get 1GB at 250 htt

 

Settings:

HTT = 250

AGP = 66 or 67

LDT downstream = Auto

LDT upstream = Auto

LDT/FSB = Auto

CPU/FSB = x 8.0

 

CPU Vid = 1.5 V

CPU Special = 110%

Chipset = 1.7 V

AGP = 1.5 or 1.6 (this doesn't make a big difference)

DRAM = 2.9 V (this is the very least and you might have to go to 3.0 or 3.1)

 

 

 

In the GENIE settings:

DRAM Frequency = 200 (1:1)

Command Per Clock = Enable

CAS Latency = 2.5

Ras to CAS = 3 or 4

Min RAS = 7

Row precharge = 3 or 4

Row cycle = 12

Row refresh = 14

Row to row = 2

Write recovery = 2

Write to read = 2

Read to write = 2

Refresh period = 4708

Write to CAS = Auto or 1

 

DQS Skew = Increase

DQS Skew value = 255

DRAM Drive Strength = Level 2

Max Async = 8.0

Preamble = 6.0

Idle = Auto

 

forgot the name to some settings here at work but one you want at 16x and the other you want at 6x, and disable the rest like the granularity.

 

 

 

This is the most stable of any setting for 250 FSB I have tested on 5 different sets of 1GB packs of ram regardless of the ram type. Some ram can get a tad better with 2.5-3-3 versus 2.5-4-4 and some like a good set of BH5 can do 2-2-2 with enough voltage. Talking at least 3.4 V here though for that.

 

Give those settings a try. I've spent several hours every day for the last few WEEKS doing this. If this doesn't work then you may have a dud of a CPU or memory at that point. I have been able to get 250 stable with memtest86+ and prime95 running for 10 hours on every crappy board I've tested. This is despite the memory or CPU I've used.

----------------------------------------------------------------------------------

 

after applying these settings the system won't post and would beep continuously.

 

so i reset the cmos by jumpers and it booted fine.

 

i went back to default settings and booted it back to windows with no problem.

 

after that i turned off my system and left for work.

 

I came back and turned it on and nothing would show.

 

the monitor light would keep blinking.

 

i have spend the rest of my evening trying to figure this out.

 

but no luck and i don't know what exactly happened.

the power led on the system case won't lit up.

 

does that explain psu is dead or the mobo is dead or both or neither.

You won't need it just to see if the computer will boot and that is all you are looking to do here.

i tried with the other 250 watts psu.

 

no cpu, no vid, no ram installed.

 

only the mobo and the psu.

 

the lights on the mobo will go red.

 

but there are no beeps and the case power led won't light up either.

Did I read this right "no cpu, no vid, no ram installed." ??? You need the CPU and

a stick of memory to go anywhere at all.

did that.

 

installed the proc, heatsink and the ram. the system doesn't beep or the power led doesn't light up.

 

the nforce3 chipset is getting extremely hot and the surroundings pcb of the chipset is unusually hot..

Okay something ate the big one. If the MB isn't even posting the chipset shouldn't be getting

hot at all. Pee warm at most if that.

 

Suggest you shoot a kindly PM to Rgone or Angry_Games. They are here to help you

in just such matters.
