Inspiron 9400 overheating/fan control/high cpu usuage with Windows 7

Thread Starter 
I have recently installed Windows 7 64 bit on my Inspiron 9400 and I am having problems with the fans kicking in at full blast and when I check the cpu usage, it stays around 100%.

I am running on a C2D T7400 processor with the Nvidia GeForce Go 7900 graphics card.

I thought it was a driver related problem, so, made sure to install all correct drivers and also install the BIOS A10 update.

When I was on Vista, I was using i8k, but, with the driver signuture problem, I haven't bothered on Windows 7.

The problem normally happens when I am listening to Itunes and then also go onto facebook apps like yoville or farmville.

I can only get the system back to optimal after a restart, which, can be a bit of a pain as you might imagine.

Ian.

Tried cleaning out fan and vents and use different driver versions? Some works better than others.

It's been cleaned just a few weeks ago, as, I decided to get an upgrade.

What drivers do you suggest I try?

I am right in thinking that my system should be able to cope with 64 bit Windows 7?

Cheers.

Sure it can handle Windows 7. The issue is always with drivers. I would start with nVidia Support Site and get what they have first and see.

Windows update wants me to install a different nvidia driver than I have got, so, maybe I should start with that.

Am I right in thinking that I should delete the current driver before installing another?

Cheers.

It is always a good idea.

I have tried the XPS driver for the same card as there wasn't a current 64 bit driver on the dell site for the Inspiron 9400, but there was for that and I have heard that they can be used on different Dell machines.

Seems to be running well at the moment although cpu usuage is still around 60-70%, but, I imagine that is normal when running programs like Itunes and certain apps on facebook.

Thanks for the help

Review your start up processes and antivirus settings. Give it also a few days and see if Windows settle down after all the disk and memory re-arrangement.

My Inspiron 9400 E1705 began to act a little strange, thought it was dying on me. This model has the ATI Radeon Mobility X1400 graphics card and runs Windows (XP) Media Center 2005.

Did a lot of gaming on this machine (COD2). One of the  symptoms was not booting (no error messages) and if it boots there was high CPU utilization (100%) without any running programs. I ran SpeedFan (http://www.almico.com/speedfan.php) and noticed my laptop was running hot. You could also feel it when placing your hands on the keyboard. :)

 

After reading the Dell™ Inspiron™ 9400 Service Manual I decided to disassemble my laptop and clean the fans. http://support.euro.dell.com/support/edocs/systems/ins9400/en/sm/fans.htm#wp1000550  The're two of them, CPU fan on the left and GPU fan on the right A lot of dust came out, so much the CPU fan couldn't spin any more.

 

Then I assembled my laptop and measured again, Hell what, the tempature was 10 - 15 °C lower!! Now it's boots and runs Windows (XP) Media Center 2005 as smooth as it used to do. And it definitely paid off to use a least-privileged user account (LUA) all those 5 years, because it kept my OS clean and healthy from all world wide threads. Tip: do your software research in a VM (VMware Workstation or VirtualBox) BEFORE running it on your fine working desktop/laptop and don't say "Yes" to every dialogbox that pops up. \0/

 

Last week I added some memory (3 GB max.), installed Windows 7 Enterprise x64 (SP1) and it's running smoothly. This was actually the 1st re-installation in 5 years. The only x64 driver to look for, was the Ricoh R5C8xx Card. Look for Vista x64 drivers @ Dell, it's one of these: http://search.dell.com/results.aspx?s=gen&c=us&l=en&cs=&k=Ricoh+R5C832&cat=sup The ATI Radeon Mobility X1400 x64 driver was found by Windows Update. If you have "unknown" entries in device manager, examine the Properties - Details - Hardware ID's and find the PCI Vendor ID and Device ID. Like: PCI\VEN_1217&DEV_00F7&CC_0C00 Look them up here http://www.pcidatabase.com/ and then you know what drivers to look for.

 

Dell Inspiron 9400 E1705, good machine it never let me down.

The only thing that passed away is the battery (after 3,5 years). No problem for me, because I always run it on AC power.

 

Nice forum btw.

 

Kind regards from NL

My guess is that poster just popped in the 64-bit disk and let it cranking winknudge.gif

This I9400 is supposed to be 64-bit compatible with the escape clause of supporting 32-bits software best

Almost qhn :)

 

Before the Win7 installation I ran CPU-Z to see if the processor was x64 capable.

And yes, the OS is x64 but most of the programs I run are x86.
