Computer shuts off randomly after about 5 min?

Question

Whenever i start up my computer it just randomly decides to shut itself off after about 5 min. I already check about it overheating and this isnt the case. The fans are fine. My question is could this be a power supply problem? My computer has been working fine the past year and it just suddenly started to act like this.

For everyone who answers with "this might be a virus" its not i checked

Answer 1

of course it isn't a virus, but i have found that it's the most common answer here. it is though entirely possible that the power supply is overheating and causing the shutdown. I would also check the cpu heatsink and see if it may be clogged with dust. one other thing to check would be the cpu fan rpm sensor. if that is failing and the sensor reports 0 rpm to the motherboard, it will shut down to protect the cpu. get a program called speed fan. it's free and you can monitor the cpu fan's rpm with it.

Does your computer repeatedly reboot at random, or randomly shut down and won't start again for several minutes? There might be several reasons why this occurs, but overheating should be your prime suspect.

If you suspect your computer is overheating, the first components to check are the fans. While nearly all systems have a fan on the power supply, many modern systems have a fan on the front of the case to push addition cooling air over the CPU, a fan on the back to push hot air out of the system, and side or top fans to move additional air in and out of the chassis. In addition, many systems have a fan mounted directly on the CPU and either directly on the high-end video card or on the side of the case over the AGP slot where the graphics card is located.

Whether your system has one fan, two or more, check and make sure they are all running. If a fan is turning slowly or not at all, you might be able to salvage it by carefully cleaning the hub or bearings. However the best plan is to replace the fan as soon as possible. If it is the fan on the CPU, turn off your system immediately and replace this fan or bring your system in to an authorized repair depot to replace the fan. (Caution: replacing a fan on a CPU can be tricky. You don't want to damage your processor. If you have any concerns, make sure to have a professional replace of this fan.)

Dirt and dust are the next major cause of overheating. Dust is an excellent insulator and a layer of it on critical components can keep cooling air from reaching the chips. Shut off the machine, open the case and blow out the innards with canned air. And don't forget the fan on your power supply; these can become clogged as well. Be prepared for a small dust storm, even if your computer is only a few months old.
As an alternative, there are small vacuum cleaners that are designed for computer components. These too will clean a lot of dust out of your system, but you still might need canned air to reach the components that the vacuum cannot reach.

Don't try to run your system with the case off. It not only does not improve cooling, it actually hurts it because modern cases are designed to direct airflow where it is needed. For more on running your system with case cover off, please see My Computer Is Running Hot. What Should I Do?.

It's important that the computer have an unobstructed flow of cool air. Computer desks that hide the case inside a drawer or elsewhere need lots of ventilation to keep that all-important air flow. It's also a good idea to keep the case out of direct sunlight and away from other heat sources Generally speaking, your computer is comfortable at the temperatures you are comfortable at.

If necessary, you can install additional fans in your computer, or even a liquid cooling unit for the CPU, to bring down the temperature of the critical components. And remember, you also can buy special sensors that can display your computer's internal temperature either on your screen on a chassis-mounted display. Some motherboard manufacturers, such as MSI, include a utility that displays the system and CPU temperatures without rebooting the system.

Finally, if you are overclocking your system (running the CPU at higher than its rated speed) you are putting a serious additional heat load on your computer. Try backing off to the system's rated speed.
Remember: Heat is the number one killer of computer components. However it isn't the only reason why computers might reboot randomly. Other possibilities include faulty memory, a card that isn't seated into its slot correctly and a host of other problems. But heat is generally the best place to start troubleshooting rebooting problems.

May I also suggest you see if you are overloading your RAM:
- - set wallpaper and screensavers to blank or none — they run continuously in the background and use memory.
- review your start menu – remove anything you don’t need on a daily basis — load games, etc. on an as-needed basis.
- run Disk Cleanup, Scandisk, Defrag at least every two weeks (the more frequently they are run, the less time they take).
- periodically, click Start, Programs, Run — they type ipconfig renew
(that’s ipconfig space renew).
these things should increase speed and free up memory as much as possible.

Answer 3

I doubt it's your PSU problem.. because your computer wouldn't even boot up.
But maybe it is so try to change it out with a good PSU and see if that works.

Also check your power setting Under

Right click on desktop - properties - screen saver tab - power

and see if the settings are correct.

If that ain't the case, I would look in to a virus.
If your being hacked and have a back door trojan that gives the hacker the right to do anything he/she wants, he/she might be effing with your computer.

I would try to run a full scan with anti virus, anti adwares.

If all fails, back up everything you need and format the hardrive and put in a new OS.

If that fails, looks like a great time to upgrade your computer.

Answer 4

You assumption about a faulty power supply could be correct. Is there a way your can test it with another power supply? Sometimes a software problem will cause a system to shut down, but since you said about after five minutes that is doubtful.

Answer 5

Yes, did you check the CPU fan, that can be a cause
Then Check the power supply fan, and then the power supply itself. This is probably where the problem is. They go bad, check all your motherboard components. Make sure your power supply can support them all.

Answer 6

it could definitely be your power supply. i had this same problem before and after a bit of troubleshooting it turned out to be the PSU a but of advice DO NOT- buy a PSU from a store ex.-Best Buy they are always overpriced. instead look over tigerdirect.com OR newegg.com . but before you do that you need to know what type of PSU you have. whats the volt/wat rating? 20 or 24 pin? 4 or 8 CPU pin? sli? if you have no clue either google or a repair shop will help you.

Answer 7

I think its a power supply problem

Answer 8

you have the two been hacked, being shutdown from someones Else's computing gadget utilising cmd or your computing gadget is ineffective. There are extra rationalization why your computing gadget is shutting down. in case you have left your computing gadget on for 6 days, somebody ought to of had time to characteristic you on their information superhighway connection checklist project and hack into your computing gadget utilising cmd, (administration instantaneous). in case you think of your computing gadget is going to shutdown then pass to "start up", "Run", and interior the field form in "shutdown -a". If that would not artwork then ask a working laptop or computing gadget save and tell them the subject and that they'd desire to be waiting to sparkling up the subject. one extra tip, press "Ctrl", "Alt", "Del" and choose activity supervisor, some computers would have activity supervisor pop-up besides the shown fact that it is not appropriate, as long as your on activity supervisor then that's super. click on the tab "clientele". Then if there's a working laptop or computing gadget call you do no longer understand and is not any longer meant to be on your computing gadget then spotlight the call of the computing gadget call by way of clicking on it and click disconnect on the backside. that's going to sparkling up the subject. If no longer then like I stated, in simple terms take it to the save!

Answer 9

Try restoring your computer to a previous day before it started acting up. If not that make sure you run a scan for viruses .......ya never know

Answer 10

Try reconfiguring your battery backup (if any) and your power supply
also check your power options
