Plz help.My newly built Computer Hangs and shows Blue Screen Error.

[antonykraj]

This is my Sys config
Amd Athlon X4 635
Asus M4a78lt-m le
Corsair 2 gb ddr3 *2 value rams
corsair vx450 psu
seagate 1tb hardisk
sony dvd writer
cooler master elite case

OS;Win 7 64 bit

The problem started from day one when i started to test the reliability of the system using Prime 95 .
When i ran the torture test , it ran for a few seconds then one or two cores started to show illegal summout error and stopped.
i checked the temp using cpu monitor and it was quite normal.
I disabled the AMD cool and Quiet feauture and tried running the test again but i get the same error.

The problem doesnt stop at that level,
Firefox crashes too often and computer seems too slow sometimes.
i often started getting bluescreen restarts in the middle of something,sometimes while playing games and sometimes while just browsing in firefox and got the following errors

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.256.1

I have even run memtest for 25 mins and found no error in my ram and also ran the windows memory diagnostic tool and didnt get any errors .
I even did a full test of my Seagate hardisk using seatools and found no errors.
Plz help me solve this problem.
Thanks in advance for the help

Check to make sure your heatsink is properly secured, so as to prevent overheating.

does it give you a STOP code (0x0004000, etc.)

thanks for the reply
no i dont think i recd that code.

I checked the heatsink it is firmly affixed .What is the optimum temp for Amd x4 635 proc?
But i dont think the system hangs on overheating it just shows Bluescreen and hangs in various circumstances.

One more thing i forgot to mention, i removed one piece of ram and ran the system with just a 2gb stick and ran prime95 without errors but the system seems to hang and be too slow even while browsing on firefox and doing nothing else.

Have to admit i don't have a clue what the best temp would be but generally idle around 30-40 and max of 60. The "fail" point is chosen by the board, not the chip IIRC. Normally around 80-100. (Degrees in Celcius)

Also are you OC'ing? Or maybe putting manual settings in the BIOS?

"Illegal sumout" sounds like, quite literally, an illegal output, or a calculation that is just plain wrong. If your RAM tests OK then it's your proc, which lead me to the overheating. If you're OC'ing, or putting in manual settings, you might need to increase your voltage, apparently (http://www.overclockers.com/forums/showthread.php?t=303896)

i think voltage will be the problem here in my case.i havent touched the system deafaults,but here in many threads i found out that sometimes the stock settings in the motherboard would not be adequate.
But i have no idea on increasing the voltage.
can u help?

 

[internetlad]

it all depends on your board and BIOS. Do you know how to get in the BIOS and where to go in the BIOS to change your voltage?

 

[internetlad]

If you have a paper copy of the manual, peruse that, there should be a section on your BIOS and changing Voltages, If you don't it is available Here http://www.asus.com/Motherboards/AMD_AM3/M4A78LTM_LE/#download

EDIT: the settings you're looking for seem to be in the ADVANCED tab.

Try setting VDDNB Over Voltage to 1.20V. See if you see an improvement there.

i have tried the option with no improvement
