ok so I recently setup a new system for myself.
Hardware as Follows
asus M4A785-M Motherboard
4GB DDR 2 Ram (dual stick)
Seagate 1 TB HDD Sata
Asus Dvdrw Sata
AMD Phenom II 6 1090T Black
stock heatsink
AMD Radeon HD 6850 Gfx Card
Linksys Wifi N dual band pci Card
Windows 7 Home Premium
Corsair 600W PSU

ok the issue i'm getting is Heavy screen pixelation then Blue Screen memory Dump Crash. This issue actually tends to Happen only during Light Computer Usage (Itunes or FireFox) or system Idle.

I have had 1 crash during Gaming

Self Tests i've done so far

1. reinstall OS
2. change RAM to slots furthest from CPU
3. Remove Pcie Gfx and tested with Onboard
4. Tested Ram for several days in Seperate machine

Cpu/MB temps when Idle are in the low 30 Celsius Range, and 45-47 Celsius under full load gaming

i'm getting the impression that there is a problem with the Mobo. But i deffinately could use a few more opinions.

Thanks in advance

Looks like the video card is bad. Try the newest drivers but that looks like a hardware issue.

I'd agree but as stated above This issue happens with both Onboard video and pcie Video. So i've ruled out my video card as being faulty,

Drivers are standard AMD drivers for video. I have removed and installed them several times to rule out the bad driver option.

Give us the STOP code for the blue screen. It's something like STOP 0X000000....



Full Stop Code String
STOP: 0x0000007E (0xFFFFFFFFC0000005, 0XFFFFF88005220FFB, 0XFFFFF88002B23698, 0XFFFFF88002B22F00

That error could mean a lot of things.

In My Computer right click the OS HDD/Properties/Tools and check for errors.

Check what brand and make is your RAM and what is the manufacturer's recommended voltage, your motherboard could give the wrong voltage. Standard DDR2 voltage is 1.8, check in the BIOS but many DDR2 RAM sticks require more. Try with one stick at a time, the RAM works differently on different mobos.

ok I checked my Mobo User manual, and the website downloaded the list of "supported memory"
Voltage ranges from 1.5 - 2.4
My Ram is Timing 5-5-5-12 DDR2 800mhz 1.9 Volt
Ram Overvoltage is set to "auto" in the bios. I over rode that and set it specifically to 1.9 testing now

I have the memory placed in A1/B1.

Good. Test with one stick if it does it again.

ok manually
set the timing in the bios from auto to the Ram specified 5-5-5-12
tested each stick individually in games without Crashing issues.

Now testing both again slots A1/B1
