Possible Causes of PC shutdowns and BSOD's

Hey everyone, Today I am going to be looking at a few of the reasons that you can get BSOD's or random shutdowns on your computer. There are lot of things that can cause BSOD's and shutdowns but I am going to mention some of the more common reasons.

Memory or RAM

I am going to start with the RAM or Memory as it is sometimes known. The RAM in your computer acts as a buffer between the CPU and the Hard drive. It is used to store in use programs to help them perform better than if they were loading from the hard drive. Anyway, sometimes the RAM will become unstable and loose little bits of it's memory. If this happens when a program goes to the RAM to look for part of the program that is needed it isn't there. This isn't always too bad as sometimes it will just cause a program you are using to crash, If however the part of the RAM that fails is storing part of the Windows program it can cause BSOD's. You can test your RAM by downloading a program called Memtest86 from here This program can be burned to a disk or put on a pen drive so you can boot from it at start up. It then scans the RAM and tests it for damaged sectors.

RAM Can sometimes cause BSOD's due to damaged sectors

Hard Drive

The next piece of hardware that can cause a BSOD is the hard drive. The hard drive is the part of the computer that stores all of you programs and data. If a hard drive is damaged or starts to wear out it can sometimes damage the programs that are on the drive it self. Just like with the RAM this means that when the hard drive comes to load a piece of data that is needed by windows it can cause it to BSOD due to that part of the program not being there to be loaded. It can also be caused by a head crash which is where the hard drive head hits the disk platter and scratches away the data which renders that whole section unreadable and unusable. Finding out if you hard drive is on the way out is very much like finding out if the RAM is broken. All you need to do is download this program. HD Tune runs on the computer and checks the S.M.A.R.T of the hard drive and also scans the platter for errors.

Hard Drive Errors can cause BSOD's as well

Overheating

The next possible cause of a BSOD is if the hardware of the computer is overheating. There are many reasons that a piece of hard ware can overheat. The following list is some of the causes;

• Damaged Fans
• Blocked fans (Usually due to dust build up)
• Blocked vents (Mostly on laptops caused buy covering the vents with fabric such as trousers)
• Dried out thermal paste (often on older computers)
• A heatsink that is not securely attached (damaged in transit or from being knocked or not correctly installed)

When a PC or Laptop starts to overheat it will often shut it self down which can sometimes cause a BSOD. You can check the temperature of the CPU by using a program called CPUID Hardware Monitor downloadable from here once this program is running it will scan all the sensors on the computer and report back the temperatures and voltages. If you can't even boot into windows without the computer BSODing then you will most likely have to go into the BIOS and go into the hardware or PC health section of it to see what temperatures that it is reporting. In the BIOS anything over 45c could be causing an issue, In windows anything over 55c will most likely be a problem once you stress the PC.

Overheating can often cause BSOD problems

Voltages and Power Supply

This one is a less likely cause of a BSOD but it is still a problem. Sometimes the power supply of a PC can go dodgy. This can be caused from stressing it too much (not having a powerful enough one for your hardware) or due to just the age of the power supply (The capacitors often age over time and don't hold charge properly) Also bad quality PSU's (generally less than $10 per 100w) can also cause problems. It is easy to check the voltages by using the same program as the temperature one above. CPUID Hardware Monitor reports back the voltages as well as the temperatures so you can kill two birds with one stone using this program. If the voltages seem a long way off their targets (Shown at the side of CPUID hardware monitor) then this could quite possibly be the cause of the BSOD's.

A bad PSU can cause BSOD's due to bad voltage supply

Now that you have read through this simple list of possible BSOD causes you can have a go at diagnosing the problem for your self. This will save you a lot of money if you find the problem and don't have to use a very expensive PC repair company.

AMD Release the HD 7970 3Gb Graphics Card

The graphics giant AMD have released the new AMD HD 7970 offering amazing performance on a 28nm GCN architecture. They are currently priced at around £450 which is a very high price to pay but the performance that you get is very very good. The 3Gb of GDDR5 running at 5500MHz allows a bandwidth of 264GB/s which is some serious performance. The core of the graphics card runs at a stock speed of It supports a maximum display resolution of 4096x3112. You can find the specifications of the card here

The HD7970 looks like most of the cards that AMD have made since the 5-series having an exhaust port on the back and a blower fan on the inside. These fans are usually very loud and can be a bit annoying. Often companys such as sapphire, sparkle, xfx, and gigabyte will take the cards and fit an after market uprated quiet cooler but so far there is no sign of this happening. The 28nm architecture of the new 7970 will however be cooler running and most likely quieter than the 5 and 6 series cards that were produced by AMD using a bigger architecture.

Overall the performance of these cards is a massive improvement over most of the ones currently available and being the 7970 there is always space for a 7990 to be released yet. Roumor has it that is will cost around $850 which is a very high price but it will have some very good performance.

OCZ's New Firmware Can Improve Performance, Realiability of 20nm-Class NAND Flash Memory

OCZ Technology Group on Monday introduced a new firmware technology for solid-state drives (SSDs) that can allow installation of inexpensive NAND flash memory manufactured using 20nm-class process technology into SSDs that require improved reliability.

Modern multi-level cell (MLC) flash memory that is produced using thin fabrication processors is generally less reliable than similar memory products made using older process technologies. However, manufacturers cannot keep using old manufacturing methods since they need to reduce their production costs. In a bid to maintain reliability, improve performance and lower manufacturing costs, new solid-state drive controllers and firmware technologies are needed.

OCZ Technology unveiled the Arowana Flash Translation Layer (FTL) from Indilinx. The firmware technology supports both existing and upcoming Indilinx controllers and can improve performance and enterprise capabilities and enables SSD suppliers to deploy cost-effective 20nm-class NAND flash memory.

The new Arowana FTL enhances performance of Indilinx controllers with HyperQueuing, which significantly increases sequential write speeds and random IOPS over the previous generation FTL. In addition, Arowana's support of 2xnm flash provides SSD suppliers with the ability to offer end users a more attractive product with lower cost NAND components. The new Arowana FTL also maximizes the life of low endurance flash with INXtend technology.
