Problem With Motherboard?

January 31, 2011 at 22:41:18
Specs: Microsoft Windows 7 Ultimate, 2.5 GHz / 4095 MB
My computer shuts down by itself on the average of every 15 minutes. The shutdown is equivalent to a hard-shutdown. I'm thinking that this is a problem with the motherboard. I was recently in the BIOS looking at the settings when it shut down again, so I know this is not a problem with the OS. Does anyone have any ideas?

I faced a similar problem and it was my integrated graphics which were causing this. What I did to solve the problem was get a separate graphics card and the problem was solved. So if you have a graphic card in an other system use it and see if it works if the problem persists go into bios and as quickly as possible reset the settings. Maybe you enabled an auto turnoff feature somewhere in the bios.

Last thing you can do is check you power supply. Use another one if you have to see that the power being supplied to the system is continuous and does not have any breaks. Also check the main power and the wall socket.

I could provide more assistance if you could tell the specs of your PC including your MB model no. company.

Overheating CPU or bad power supply.

Power Supply: I have replaced and experienced bad power supplys before in the past, but the symptoms of a bad power supply that I have experienced was the PC restarted at random. It never shut down on me before. Has anyone personally experienced a hard shutdown caused by the PSU?

CPU: What could be the reason for an over heating CPU? It's not overclocked and all the settings in the BIOS have been reset to factory default.

Wall Outlet: I have a console plugged into the same outlet and I use it often, so this can't be the problem.

Graphic Card: I never used the integrated graphics card before.

Thanks for the replies!!!

Bad PSU can cause this issue. It causes a restart when the power coming from the PSU fluctuates and causes a hard shutdown when the PSU cuts off the power for a bit longer so the system does not restart.

CPU can overheat without any overclocking aswell. Open your case and check if there is dust inside it. Dust can gather on the heat sink and cause the CPU temp to rise. If this is the case use a can of compressed air to clean the inside of your system.
NOTE: DO NOT use a Air/Leaf Blower as this can cause static buildup inside the casing.

The issue can not only happen with integrated graphics but also with Seperate Graphic Cards when they fail to process graphics and give out display.

Please check PSU and CPU temp first and reply back,

Hahahahaha.....so basically the problem that I am having can be caused by multiple reasons. Not the answer I was looking for, but I guess these are the facts :(

Last night I replaced the PSU with a friends and my PC did the same thing! The result, I am going to RMA my motherboard. Before removing the motherboard though I inspected all my hardware and there was little to no dust on the components. I already cleaned my computer a week ago with a can of compress air :) I will let you guys know if it was indeed the motherboard or not when I get it back. Thanks again for the help!

I found the issue. It's the CPU. I created an RMA with AMD and they told me that the CPU wasn't overheating, but it was defective. What a pain in the ass! Good news is that the PC is running at 100% now :)
