PC freezes or blue screens when memory usage is about 40% or higher. When PC is
restarted, red RAM light is on on the motherboard, and PC will not boot (even after
pressing MemOK button). Changed the RAM from 4gb of 1600mhz Kingston to 4gb of
1333mhz of Kingston and the problem has been apparent with both types of RAM.
Processor has also been changed and the problem persists. HDD has been changed
also, and still no change, PC still freezes or blue screens (normally the reason being
a memory fault, even though after memory checks the memory is 100% working).
Hello, I am the technician that will be assisting you today. My name is Norman-Wynne Damstra.
Welcome to Fixya, Tracey Laidler.
Yes you are quite correct BSOD or Blue Screen Of Death is normally due to a memory fault. However drivers are as big a culprit, especially seeing as though you have changed memory modules and processor.
Install all the drivers for this mainboard. Also enter the BIOS/CMOS by tapping the Delete key during first powering on the computer. Once in the BIOS/CMOS select the option to load defaults. Check if that works.
If not then take it a step further by clearing the BIOS/CMOS by removing the silver button cell from the mainboard for 10seconds before reinstalling it in the correct orientation.

Under the main view photo at the top left; there are 4 views shown underneath. Click on the third view from the Left. Shows a top view of the motherboard. Now it is the main view. Click on the main view to enlarge it.
See the 5 blue SATA connectors under the Blue and Black ram memory slots? Red line points to them, and subheading states; SATA connectors; 6Gbps
IF you are going to add a SATA harddrive as a Secondary harddrive, use one that is open. (Nothing plugged into it)
Which one? Does NOT matter. The beauty of SATA is, that you can plug into any one of those SATA connectors, and BIOS will find the device that is plugged into it.
(SATA 1 connector is usually reserved for the Primary harddrive, though. The one with the Windows operating system on it. [Windows XP, Windows Vista, Windows 7, etc )
Looking at the connector for the SATA data cable at the top, note the L-shaped opening.
Looking at the SATA connector for a motherboard, shown on the bottom, note the L-shape where the SATA data cable plugs in.
The SATA power cable has the same L-shaped opening. Only plugs in one way.
Caution! IF, the SATA harddrive you are going to use, has a provision for a SATA power cable, AND a 4-pin Peripheral power cable, ONLY use just a SATA power cable!
Why? Because you will burn the SATA harddrive up! Maybe not right away, but I assure you down the road it will.
4-pin Peripheral power cable,
(Also know erroneously as a Molex power cable. Molex was the first manufacturer of that type of power cable connector. Name kind of stuck. Just like calling an adjustable open-end wrench, a Crescent wrench ),
A) Computer unplugged from power, computer case open, FOLLOW Anti-Static Precautions.
Anti-Static Precautions: Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.
Relieve your body of Static BEFORE reaching inside your computer.
Computer on a table, computer Unplugged from power, computer case open; TOUCH an unpainted surface, of the metal frame of the open computer case.
IF, you leave your computer in the middle of working on it, be SURE to Touch the metal frame again upon your return.
B) Plug the SATA data cable into the motherboard. Bring the SATA harddrive closer to the computer case, and plug an unused SATA power cable into it.
Find a slot in the metal harddrive bay, that you can slide it into. Install the screws in the side, if the harddrive bay is of this type. Otherwise there will be plastic clips on the side of the slot.
That's it. Close the computer case, plug the computer back into power. WAIT 1 minute, turn the computer on.
The Power Supply Unit might either be faulty or under-powered, or their might be another cause.
Eliminate the posibilities one-by-one.
Remove the motherboard and make sure there are no misaligned mounting points or loose screws under the motherboard, shorting the solder points under the motherboard when you switch the power on.
Reinstall the motherboard carefully, making sure the Power Sopply Unit connector is fitted correctly and fully pressed into its socket. If it is a 2 part connector 20 + 4 pins, make sure the 2 part fit together in the correct orientation.
Make sure the Front Panel Control Header Pins are fitted in the correct orientation.
Make sure the CPU and Heatsink are fitted correctly.
Make sure the CPU fan is connected.
Make sure the RAM is properly in the RAM slots.
Make sure the Graphics Card and any other PCI cards are properly in their slots.
Connect only the CPU Power Cable, the Hard Drive power cable and any Graphics card power cable (if you have a separate Graphics Card and it has a power connector) and, leaving the computer open and flat on the floor so you can see all parts inside, test the computer again.
If it works, shut the computer down, add the CD/DVD drive power cable, and then the case fans, testing as you add each extra device.
Upgrade to a 650W PSU if you experience any failure or slow spinning of fans.
Afre installing the new PSU, clear the BIOS by disconnecting the power cable and removing the small, silver CMOS battery for 2 minutes and then reinstalling it and then restarting the computer.
If none of this works, then the Motherbard might either have a BIOS corruption or a power management fault and should be returned to the supplier under warranty for like-for-like or higher specification replacement or a full refund.

make sure the cable is securely seated and not faulty
the drivers might not be installed correctly you might have to uninstall the graphics card restart your computer then reinstall the graphics card and its drivers
If your computer came with a motherboard disc the drivers could be on it
Click start control panel administrive tools computer management device manager scroll to display adapters + to expand you might see a yellow question mark ? or exclamation mark ! or a red x right click select reinstall drivers or uninstall
So you changed everything except 1 thing, power supply. Try another power supply or power suply cord. If it doesn't work, try another graphic card, maybe there is some shor circuit.
Click here to view the list of supported processors for the ASUS M4A78LTM LE Mainboard.
The AMD AM3 Phenom 2 X4 965 3.4GHz is not supported as it is a 125Watt or 140Watt Processor.
The ASUS M4A78LTM LE Mainboard supports up and including a 95Watt Processor.
Therefore you either need to downgrade, purchase a Processor that is supported as shown in the list or purchase a Mainboard that supports your AMD AM3 Phenom 2 X4 965 3.4GHz Processor.
I myself would go for an ASUS M4A88TD-V EVO/USB3 Mainboard, its a good companion for that monster of a Processor you have got.
See if you are able to return the Mainboard and purchase the ASUS M4A88TD-V EVO/USB3

Hi, mine was running slow too. Like I'd turn it on and go grub some coffee, than make some toast and then after It'd bring the windows screen on. If that's the case I suggest to try different hard drive, but my guess it's motherboard issue: Here is memory information for EVO D51. Please let me know what model you have, so I can be more specific
ok u need recovery disk then u hava to fix error on harddisk. Blue sceen is error of harddisk or RAM memory but majority harddisk be eror give4s this error So boot your lapto pwith your rercovery disk then go to recovery console and type "chkdsk /r"
