Please,

I manage a cafe. Recently the computer where i installed cyber timer just shits down suddenly, as if somebody yanked out the power cable. It has been happening. I am suspecting motherboard problem or what do you guys think? It does not give any message whatsoever.

Check if the processor's fan is working and the system fan.

Series of things might cause an abnormal shut down of a system. But according to you, you said it started after finishing installing a software. That might be as a result of a hardware conflict. i.e. the one of ur system component is not compatible with the software u installed.

Try to uninstall the software and see if the problem will persist. If it doesnt, then u'll know its a hardware conflict.

It might also be as a result of virus attack.

Also try to dust your system clean.

I actually installed the software about 2 months ago , but this problem started a week ago, when i tried to open a document in a memory stick. I have a fully loaded anti-virus. But i have not checked whether the fan is dusty or something.

I had the same problem before, but when i checked inside of the system, i noticed both fans were running slowly, because of accumulated dust which resulted in high system temperature causing the system to go off. After getting rid of the dust, the problem stopped. If that doesn't stop the problem you might have to check for bad R.A.M

ONE OR THE CAUSES OF SUDDEN BREAKDOWN OF PCS IS PROCESSOR FAN FAILURE. SO OPEN AND REPLACE UR PROCESSOR FAN. THANK YOU
I JUST REPLACED MINE YESTERDAY AND IT IS WORKING PERFECTLY WELL.

* The purpose of Prefetch folder is to increase the speed at which you can access the programs that you use on your PC. Unfortunately, Windows doesn't differentiate between a program you use every day and one you use every blue moon, which means that it may be prefetching a lot of stuff that you rarely use, adding to your startup time.
You may find that the first time you boot up after cleaning out this folder, your PC takes longer to get into gear - the second, and subsequent, boots should be quicker.

NOTE: this is a 30-day trial of the program. This means that after 30 days the "background guard" protection will de-activate. However, this version can continue to be updated and used as an on-demand scanner forever.

I hope this works for you.
