I just installed Windows 8.1 on my Dell Vostro 400. and it gave me this BSOD message "whea_uncorrectable_error". it freezes and restarts until i turn it off. is there a way to make this work?

This is a bugcheck generated directly by the CPU. Most often it is caused because of incorrect voltage being applied to the CPU.
This can happen because of incorrect settings being applied to the BIOS (often resetting the BIOS to the defaults or updating the BIOS helps) Sometimes it indicates that a Power supply is outside of its correct voltage range. (power supply voltage regulators or mother board voltage regulator is in the process of failing.

Do this quick check:o n older system check your system clock and confirm that it is correctly set. Sometimes you can get something like this when you battery backup on your motherboard fails. (it the time is correct your battery is most likely ok) the battery generally is ok for 3 to 5 years before it has to be replaced


-this error is also very common with overclocked CPU's

So you're saying it has nothing to do with Windows 8.1? even though it was completely fine before i installed it?

nope, it is generated directly by the CPU and passed to windows. I have looked at the error in the windows debugger many times. Most of the time it is a error generated by the memory controller inside the CPU complaining about a cache error. if you post your memory dump I will dump the data in the debugger for you using the !errrec command. (there are many errors that the CPU can generate)

You will want to check your voltages in BIOS then boot a memtest86 CD and confirm that your hardware works as expected.
- I guess you would also want to confirm your CPU fan is also working, same with your power supply.

Sorry to bump the thread but this seems to be the issue I am having as well. Still fairly uncommon at this point but I'd say it's happened about 5 times in the past 3 months. About 4 months ago I noticed my cpu was getting absurdly hot. As in like 85 degrees Celsius under 50 percent load. (i7 4770k but at stock). Probably hit 100 degrees Celsius a few times before being throttled severely. so I took off the CPU heatsink and repasted that sucker. Totally fixed the problem. Works fine now. But I occasionally get this whea_uncorrectable_error. Could the previous overheating of the CPU have caused this? CPU rarely exceeds 60 degrees now.

overheated CPU can cause a failure in its electronics that will still be there when the CPU cools down.
you can use the windows debugger and the !errrec command on the WHEA data structure to see what the CPU is complaining about. if each bucheck complains about the same bank of cache memory then you could have a bad bank.
