Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect your hard drive

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electic extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error
hope this helps

Asus u52 shut down unexpectedly


When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

Laptop cuts off during operation and when I attempt to log back on it cuts off again.


Hi

Thank you for your query

Please do the following steps to narrow the problem down

1) Switch on the laptop
2) Once switched there may be a meeage that says press del or F12 to enter setup, if not try the del key or F12
3) This will being you into the bios screen, once in there let the laptop run, if the laptop keeps cutting out in tis mode, you will have a overheating issue

If it is overheating then try cleaning out the vent where the hot air comes out from, if that doesnt looked block then it looks like the Heat sink (the fan that cools the CPU down) is faulty and will need to replaced.

If however it does not cut out then you have a sftware issue and i would recommned a clean install

Hope this helps

Do the following:

1. Log out of your friends FaceBook account.
2. Log in to your FaceBook account.

When you are finished using FaceBook then:

1. Log out of your FaceBook account.
2. Get your friend to Log in to their FaceBook account.

Your log in will be your Email Address (or User Name you created) and your Password.

NOTE: if you have forgotten your passwords or email accounts, OR your friend has forgotten theirs.

THEN (your friend will need to check their profile information) before they log off. In the Profile, they will find what email address is listed as being the current one. (You can supply more than 1.)

I hope this information is useful to you. Please rate. Regards

2log(base4)x + log(base4)3=log(base4)x-log(base4)2


Hi,
It is easier to use the rules for logarithms to clean this equation before trying to solve it. And the calculator is no help here.
Let me represent the logs as follows log b in base a = log(a,b). The first argument is the base.

2*log(4,x) - log(4,3)= log(4,x)- log(4,2)

Here you have two similar terms 2*log(4,x) on the left and log(4,x) on the right. Gather them both on the same side, say the left. You have

2*log(4,x) -log(4,x) +log(4,3) = log(4,x)-log(4,x) -log(4,2)

which is equivalent to log(4,x) +log(4,3) = -log(4,2)

Gather the constant terms on the right, and use log(a) +log(b)=log(a*b)

log(4,x) = -log(4,2) -log(4,3) = - { log(4,2)+log(4,3)} = -log(4,2*3)

You get log(4,x)= -log(4,6).

Take the constant term to the left, while changing its sign in the process. On the right remains 0, which is also the log of 1 in any base So log(4,x)+log(4,6) =0 =log(4,1)

Use the rule log(a) +log(b) = log(a*b) valid in any base, to obtain
log(4,6x)=log(4,1) which is equivalent to 6x=1. The solution is x=1/6

There are a few other shortcuts to get the solution but I preferred to take a pedestrian, step by step, approach.

Hope it helps.

Dell Optiplex GX270 - Freezes up!


You may have either a memory chip gone bad or the CPU overheating. Withot seeing it and testing it's hard to tell you which. But one thing you can try is if you have 2 RAM installed, try to remove 1 and see if the problem continues. If so, change them and put the one you removed back and remove the other. if it continues then you may have an overheating problem.

Otherwise, you can try a SCANDISK and DEFRAG to clean up the hard drive and data.
