why does my pc always restarts from its own ?

Question

i have ibm pc its restarts from its own ,,,why? what can i do ?

Answer 1

There could be several reasons for this.

1. PC may be overheating. Some motherboards will shut down and reboot your PC if it exceeds a certain temp. threshold. You can adjust this higher in your BIOS and it'll raise the tolerance level before shutting down, but this is not a real fix since the reason it is shutting down is to protect your PC from burning out. If your case has room, try mounting an extra fan and see if that helps.

2. If you have any overclocked components, make sure you have sufficient cooling or else you get the same problem as above.

3. Bad component on one of your peripherals. It could be a faulty component or damaged capacitor on your motherboard, video card, RAM, power supply, etc. The only way you can troubleshoot is to swap out and test each component individually and it's difficult to diagnose in this case unless you have spare parts around.

4. Virus or malware. Some viruses and other malicious programs can cause this to occur. Make sure you have an antivirus, spyware scanner, firewall, and a fully patched Windows to detect, protect, and remove any bugs that could potentially infect it.

5. Software conflict. Certain applications just don't get along with different software configurations and may reboot if errors occur. If you get frequent blue screens and "red x" memory errors along with reboots then this could be the case.

Answer 2

Common causes for restarting-
1: Heat (dust and dirt build up on the cpu and inside the psu)
2: Viruses (remember the Blaster worm?)
3: Failing componentry (usually capacitors on the motherboard or in the power supply start to go bad, I see this often).

The first 2 are ez to check for, take it apart and clean it out. Use compressed air and a soft paint brush. Scan with a good online scanner like trend micro, bitdefender, or kaspersky. If it's not heat or viruses, then failing hardware is likely a culprit. Usually bad capacitors can be spotted by simply looking at them. Look at my profile (letmepicyou, obviously) photo in yahoo if you want to see a picture of what bad capacitors look like. GOOD capacitors are flat on top. If they're starting to bulge even slightly or look like they've leaked they are BAD. If you're uncomfortable with troubleshooting hardware after you've eliminated the dirt/virus possibility, take it to a reputable shop.

Answer 3

If it shows you a coundown that your PC will restart in a minute or something like that. Then it's an issue with the RPC service in your computer.
You can fix that my by going to:
Start->Run-> type 'services.msc'
Then select RPC from the services list. Then click on "Recovery" tab. And change the "First , second, and subsequent failures" settings to "Restart the Service"

Answer 4

probably a heat issue i would go buy a can of air unplug the pc pull the sidecover off and blow it out paying special attention to any fans or heat sinks

Answer 5

there could be many reasons for that, hardware fault or software fault.

1))over heating
2))conflict either software or hardware
3)) right click on my computer icon-->properties-->advanced-->start up and recovery-->uncheck automatically restarts.

Answer 6

it could be from either a virus or if your computer auto updates and restarts to complete the installation

Answer 7

If your computer is not working properly while you are working on it, it could be a problem with device drivers, hardware or software.
