The system is working perfectly a while ago. Not quite sure what has gone wrong when it becomes obvious that it requires some attention after repeatedly tripping off. The fan whizzes intermittently and there is no time to be at ease because it's not something one is usually familiar with. At the very least, as a general user, checking the power cable is the first thought that comes to mind, yet nothing seems to be coming from that area.
To loose mind over a computer switching off without warning is a reminder of the important files which are saved on the hard disk, to be precise, one needs to be cautious of them. Not only that, the typical running of day-to-day activities are halted as one can no longer power on the system for use. For these purposes, not receiving any warning before hand is a sign of something critical happened within the internal working parts of the system. It could have been failure to make a routine check up for quite some time before the problem, something that's not so much different from human visiting a doctor for check-ups for a healthy living.
However, there different causes of this issue can be summed up to be system failure. Knowing the symptoms are the path to solving the problem without having to fret over losing important data. In this case there are steps to follows in solving the cause of the problem. There are four typical ways and there can be more to follow in course of any of the approach.
Firstly, it can be virus. To troubleshoot that follow the steps below:
Step 1: Remove the power cord from the main to disconnect from any power source.
Step 2: Press the power button holding it down for at least 10 second to discharge the system of any current - that's doing an XT reset.
Step 3: Replace or insert the power cord to the power socket and push the power button to start the system.
Step 4: Immediately at boot press F8 before the system logo and select Safe mode among the Windows options.
Step 5: Run the antivirus for the system. To remove malicious software from a system visit this link .
Step 6: After deleting or removing the malicious software restart the system to make changes.
Secondly, it can be faulty hardware parts. To troubleshoot that follow these steps:
Step 1: Remove the RAM and clean the gold contact and connectors. Replace it and start the system.
Step 2: If there is not progress with the RAM cleaning try to use another working RAM of the same specification.
Step 3: Check for broken power cable by replacing it with a working one.
Step 4: Check if the power pack is working by testing it on another system .
Step 5: See if the mobo(motherboard) is faulting by looking out for the power LED or console.It is at the front of the CPU.
Step 6: Check if the fan is dead. If it's not working it needs to be replaced.
On a side note, it is not generally possible to have all of them having problem at the same time. Any one of them can be a potential culprit.So, test them is the quick way of finding out the one causing the problem.
Thirdly, it can be overheating. To test for overheating follow the following steps:
Step 1: Open the system and dust the cooling fan of debris or accumulated dirt.
Step 2: Check if the micro-processor is the recommended one for the mobo by searching Google for the motherboard specifications.
Step 3: Check for overclocking of the computer. That's check the CPU operating speed at the BIOS(if very high try to reduce it), check the memory timing,etc. These can actually make a system to overheat thereby causing it to switch off without warning .
On the final note, it can be Windows operating system not well installed. If that is the case follow the next steps:
Step 1: Insert genuine windows installation disk into the system to load system files.
Step 2: After some minutes Windows options are displayed, choose repair by pressing R in Windows XP or select 'Repair' for Windows Vista, 7 and 8.
Step 3: The Windows tries to replace missing files and repair the system.
Step 4: If that did do the work. do new Windows installation on a different partition. After successful installation save the important files to external of different partition that must be well tagged or renamed for careful purposes of not losing them.
Subsequently, it can also be due to use of pirated Windows installation disk or not activating the Windows after the time limit of the free trial.
