Query about AMD 6000+ Processor

The only thing i can suggest is remove one of your RAM sticks and see if the machine will boot. I had this problem with mine and it turned out that one of my RAM slots was faulty and would not boot if both RAM slots had RAM in them.

Sounds like you built this puppy.

1) Does it use metal standoff's to hold the motherboard up off the Support Plate? (Standoff is metal, Spacer is plastic)

Do the standoff's match EVERY mounting hole in the motherboard?

To wit, there isn't a standoff sitting on the support plate, that doesn't match up to a mounting hole in the motherboard?
If there is a standoff in the wrong spot, it could be shorting against the exposed solder joints on the bottom of the motherboard.

2) is the 4-pin +12 volt power cable from the Power Supply plugged into the motherboard?

[ Two Yellow 12 Volt wires, two Black Ground wires ]

3) Thermal paste applied, and properly? AMD processors don't play when it comes to heat. If they reach the thermal limit, (Like any Processor), they turn off, BUT, an AMD will turn off in a heartbeat.

Heatsink sitting flat on the top of the Processor's case? I use a 'birds-eye' view with the mobo out, and look across the side. (Sides, ends)

4) Zalman fan doing it's thing? Spinning?
Spinning all the time, no intermediate spinning of spinning a few times, and stop?
Spinning at the proper RPM?

5) Patriot ram seated well? Locks are in tight?

Didn't get bumped when you were hooking up power cables?
Remove/re-seat. Only takes a few minutes, and will help you sleep better tonight.
(Both of those ram memory modules in the same channel?)

6) Power Supply known to be good?

What is with the 40GB Seagate harddrive? Typo, and meant 400GB?

The M3N78-em mobo doesn't support AM3 processors. It is an AM2 / AM2+ platform. A wonderful GPU for you would be this. http://www.newegg.com/Product/Product.aspx?Item=N82E16814102858

If you have any other questions please write back in this thread. I will be happy to help you through your computer upgrade.

if you want your drivers for your mobo go to asus.com and find your model and download that

You might try switching the VGA cable if you haven't. If that doesn't work then I'd agree with you in saying the motherboard is likely fried.

its approximately 44,000/- (INR)

please check whre u have connected ur monitor comm cable, is it in agp card or on borad display card

How long have you had the system in that configuration? It doesn't seem to be a heat issue running around 45 degrees unless that is the idle temp. I need you to try something, when it shuts down, immediately restart the system in bios and look at the temp for the processor again. I solved my issue by taking a side off of my case and putting a small desk fan blowing directly into it. My idle temp went from 45 down to 27 degrees celcius. In a perfect world, the cooler a CPU runs, the better the system will respond. Find those temps readings for me, and let me know. Also, there may be a small monotoring program in your mobo set up disc to help monitor the temp while windows is running. And also, double check to make sure your processor fan is plugged into the correct spot on the mobo, mine is mislabeled, another issue I had found and corrected.

ya it has ddr u could beef ram up aint much chip u can get higher in this mobo need new mobo to run quad cores amd ect is am2+ mobo better cheaper ram too get more up to 8 gb 16 sum mobos on new egg
