Processor running at 95c after bios update

Specs: Windows XP, e8400, 2gb Ram
hi. my pc was occasionally restarting but no serious hardware issues, a microsoft error report said probably due to bios problems. i used abit uguru to automatically update the bios and since then i am getting alarm beep that processor is running at 95c (this was confirmed by 'speedfan' program which gave similar reading). two questions really, guessing here but could the incorrect bios have been loaded and would flashing correct bios cure it. if so how do i go about doing this, i have no floppy drive and although i have managed to create a bootable usb and put the latest bios for my board on this, i can't get any option to boot from it in the bios menu. if not a bios problem what could it be? as i said there were no hardware problems till the bios was changed. all fans appear to be working normally and heatsink is properly seated on processor. My system has Abit ip35pro xe board with e8400 processor.

You need to clean off and reapply the thermal paste on the CPU Heatsink and also clean out the dust from the heatsink fan :

Did you reset the BIOS to defaults after the update?
This is standard practice and not doing this can cause a variety of problems. If the system requires any special settings they would have to be manually set again.

It is barely possible that an incorrect BIOS could do this but it is highly unlikely. The usual result of an incorrect BIOS is an unbootable system.

If the CPU is running hot, it's running hot - a BIOS update isn't gonna fix it. You need to remove the heatsink from the CPU, thoroughly clean it AND the top of the CPU, apply a fresh dab of thermal paste, then reinstall the heatsink. Find the instructions here:

I have essentially the same board and cpu that you have. The E8400 is known to have temperature sensor issues, and the temperature that you see reported in the bios may not be accurate. Check the PWM temperature in the BIOS-if that's OK, my guess is that your cpu is NOT overheating. I use RealTemp to monitor the cpu temps, since the BIOS reports a completely unrealistic temperature-much higher than your's. The PWM, however, is OK,

Hi again. thanks to all who replied. I replaced the heatsink/fan today, unfortunately this made no difference, temp being reported as 93 to 95c. As suggested by kx5m2g i checked PWM temp in bios, this was showing in the low 30s as was system temp, so I installed RealTemp and this reports processor at 31-33c when idle. Still don't know why i had never had an alarm beep before i updated bios but now just relieved computer isn't going to burn up anytime soon. Thanks again, especially kx5m2g!

ctb: I would still keep monitoring the cpu temperatures. Hopefully, as I suggested, the 93 to 95c temperatures are not accurate. That's not a totally unrealistic temperature, whereas what I see in the BIOS is something above 200 C. If you run something like Prime 95, see what Real Temp reports and if the core temperatures start going up as they should when stressing the cpu.

Hi. Have now found a link on another forum where someone was reporting same problem with the IP35Pro XE board and a E6300 processor. Turns out that the problem lies with the bios update that is available on the main Abit site. Someone posted a link to a beta version of the bios, I downloaded and flashed this and problem appears to be solved, bios now displaying cpu temp of 44c which sounds much better. Thanks.

I'm gald it was solved with the BIOS update. “Someone posted a link to a beta version of the bios”–could you post that link, or send it in a private message ? The latest BIOS I can get for the IP35Pro board from Abit's website is May, 2008–I don't have the XE version, though, so that's probably the latest I can get for my version.

I'm gonna guess the bios is miss reading your temps. ut your hand by the cpu fan. you can tell the difference between 40c and 90c. The software generally just read what your bios would say and so if your bios is faulty they will be also. First using a your hand figgure out if it is actualy over heating. IF not revert your bios or use a beta. If you can manualy tell is not over heating you can probaly diasable the armes in the bios

Hello, I have this EXACT same problem I also have an E8400 and it also started happening after flashing BIOS, first reboot after flashing BIOS it said bad cmos checksum coz it was flashed then I put put default settings and it did and everything is normal but now the temp problems are there.., even tho Im happy that it's not actually so hot, the computer shutting down automaticly because it thinks it is soo hot is a problem.. is there any fix?

Read response #9: You can disarm the alarm. Just uncheck the box where it says shutdown temperature.
