BSOD (Blue Screen)

A lot of BSOD`s are caused by faulty ram/underpowered psu`s/overheating/overclocking/dust and debris.
There are a few things you can do to solve your problem
First run a complete disk check.

Click start/run and type chkdsk /f /r and press the enter key.
Follow the onscreen prompts and reboot your computer.
Windows will check your hard drive for problems.

Depending on the size of your hard drive, this can take quite some time.
another thing you can try is First, turn off your computer and unplug it from
the main power and disconnect all cables then push the power button to fully drain the power
then open it up.

Clean out all dust, dirt all that stuff, especially from the heatsinks and fans.
A can of compressed air is very useful for this part.
Next, take out your ram sticks and gently clean the gold contacts with an eraser.

Blow away the remains on ram, also blow out any dust that may be in the ram slots.
Reinsert the ram. Restart your system and see if it becomes more stable.
You might also want to try placing the ram in a different dim slot.
Check your system for overheating. The free Everest program is useful for this.

Check that your psu is putting out enough power for your system. Especially,
check that there are enough amps on the 12volt rail.
An underpowered psu can cause all kinds of random crashes.
Check that your pagefile is ok.

Do the following.

To do so do as followed right click my computer, and select properties,
and then the advanced tab under performance, click settings.

Click on the advanced tab, and then on the change button click on the custom size button,
and click the initial size box and make the size of the page file 0.

Click in the maximum size box, and make the size of the page file 0 now click set.
Now all you have to do is reboot your machine. After your system has restarted run a defrag.

Once the defrag has finished, go back to the pagefile settings above,
and click on the change button. For the initial, and maximum pagefile size make it 1.5 times
the amount of ram your have.

Ex.if you have 512mb of ram set the page file to 768mb.
Once done click on the set button, and reboot your system.
You now have a brand new page file.
