Usually when this happens it is due to the thermal monitor in the cpu telling the system it is overheating. This can be caused by a weak or worn out cpu heatsink/fan. I would recommend replacing the heatsink/fan assembly with a new one making sure to use a good quality thermal grease between the heatsink & cpu. Reassemble and see if that fixes the problem. Hope this helps & please remember to rate my answer. Thanks.

My Gigabyte Mother Board shows some time Load Optimized Defaults then boot / Load Optimized Defaults then reboot / enter BIOS. How to fix it?

Two things come to mind first. Number one would be making sure you have the most up to date bios. Number two would be that maybe the motherboard battery is dying/dead and isn't holding enough charge to after being shut down to save the option you selected.

Hp presario f600 boots and runs but screen wont cut on

Well if you are sure the computer is running, then you could have a bad inverter, take a flashlight and shine it on the screen, if you see the icons and computer booting, then you have a bad inverter, go on amazon and order another LCD. also if you have a desk top monitor, connect the monitor to your laptop, then boot up your laptop, hold down the "FN" (function) button and press "F4", you should see everything on your desktop monitor. Good luck.

P5L-MX fails to boot.

If the motherboard is powering down at random intervals after powering on, that might be a hardware problem that's non-recoverable, like a failing capacitor. The only other thing to check is if anything is electrically shorting the motherboard - does any wire in contact with the board have a split in the insulation, is there a fallen screw, etc? Check behind it, too, and make sure it can't be shorting against the case.

The only other thing you can try is to reset the BIOS. Check the motherboard manual for the specifics. It involves unplugging the system, removing the CR2032 battery, and moving a jumper for a few seconds. That will factory reset all settings and possibly help if your issue is BIOS-related.

You could be onto something with the power supply - especially if it's one of the rails that powers the motherboard that's acting up. Cross-test your motherboard with another power supply to be sure. If you can't bring a power supply to you, take the motherboard to a computer and just stand your motherboard on the floor and stretch the connectors you need from the other computer. (This is less invasive than ripping out the power supply if the other computer isn't yours)

If you notice the motherboard powering down even on another power supply, after a full reset, I think it's toast. :(

Hi I have a HP pavilion a708uk pc when i power up the cpu fan run full speed the the screen says "hibernating" then shuts down! any ideas?


You can try the following steps to resolve this issue:
Turn off the computer
Remove the power cable
Press the power button and hold it for atleast 8 seconds
Reconnect the power cable
Try to restart the computer and see if you are able to get on to the Desktop.
If the above steps does not work and you again get the "hibernate" screen, immediately press the "Esc"(escape) key on your keyboard. It should let you go to Desktop.

Once you are able to boot normally do the following:
Right click on Desktop
Click properties
Go to Screensaver Tab
Click on Power button
On the Power Options Properties Window, click on "hibernate" Tab
Uncheck "unable hibernate"
Press OK

Hope you find the above information helpful.

New motherboard put in my hp pavillion dv6262 in January when computer wasnt even 2 years old. Computer is trying to start up showing a black screen and within a few seconds shutting back down again. Is...

I have reviewed your problem and have the fallowing items for you to check and or try.
Try booting into safe mode and see if the same thing happens.
( F-8 )
Choose safe mode with network configuration installed.
If the unit runs without shutting down, it is a program conflict and not a hardware issue.
Run this safe mode start up, with no external devices connected.
Note... Remove any Flash Cards or USB devices, CD or DVD's .
If the unit runs without shutting down in safe mode, you may want to run a complete restoration of software.
Hope this helps.

My system shuts off abruptly....

Download Coretemp from here:

Run this program and see if your processor is really getting hot(or at least the system thinks so). You could have a bad processor, bad heat sink, motherboard, fan, etc. The first step though is to see what the system "thinks" is going on.

You might need to cool the machine down first to be sure that you can get to the point of being able to run the test. Watch the temp and see what happens. Hopefully it will give us some clues.

I'd download the program on another compute and put it on a memory stick so you'll be able to get it running ASAP when the system boots.

Is this a laptop or a desktop? Also, if a desktop, is it a namebrand or whitebox/clone?

If it's a desktop one thing you can try as a temporary fix/diagnosis aid is run the machine with the cover off and a powerful fan blowing directly on the processor.

Very slow booting

If you're going to plug-in a video card you need to turn off the onboard video chip. Otherwise It sounds like a cold problem, you could heat areas of the motherboard with a hairdryer to find out..
