My operating system is Windows Xp. Once I open it, it will restart automatically in several times. I already checked the connections of the cables and it is plugged firmly. What should I do? thanks.

Thanks. We'll let you know when a new response is added.

There could be a lot of causes.First of all, what make/model PSU [Power Supply] you have???
Open the case and see does your cooler on processor is dusty. And check also other components.You can clean them with vacuum cleaner or with compressed air.Maybe your processor is overheating and you should replace paste between processor and cooler on processor…
What anti-virus software you have? Maybe there is no good protection.Those viruses that go into startup and if they hide in root where is your Operating System are tough to clean so I could advice you to go into Safe Mode and backup all important data before you start to do something serious…
Hope this will help you.

    One of the main causing of a system rebooting is the motherboard overheating. You might want to check to see if the fans are working properly or if there is dust causing overheating on the motherboard. Just use some canned air to clean it.

    Agreed, most likely overheating.

    However, Windows XP is now too old and obsolete. An incompatible driver or hardware device could also cause it to reboot.

    The event logs would be a good place to start investigating, to make sure it is not OS-related.

    The best is to clean everything from your CPU fan, casing fan, motherboard and case. Then put a new thermal on your CPU and reattach your CPU fan on the CPU. Also check the settings on what is the temperature before the PC restarts in the BIOS.
