Precision M4400 Owner's Lounge *Part 2*

Make sure the heatsink is tightly in contact with the cpu after installation. Probably it overheats and the machine turns off.

 

Lately I've been having with my screen freezing randomly.
It seems to appear when I've left the computer on for a few days.. then everything freezes. mouse cursor doesn't move. etc
after several minutes, the screen turns blank and the bottom flickers.. here's a video of it
M4400 - YouTube

What do you think is causing it? I ran memtest.. memory seems okay.. I ran HD Tune.. doesn't seem to have any bad sectors
I'm on Bios A26

 

Just a guess, but I am thinking something with the video card.

Which model do you have, the FX 770M or the FX 1700M?

 

no , i think is not this the problem...

there's some diagnostic led book ? the three leds over the keyboard ( firts "9" , 2nd "A" , 3rd "arrow" ) are activate and the "9" is blincking...

 

I have the 770M and yeah I'm starting to think its the video card too!

 

Documentation


find , but i think is not the processor ( maybe the slot processor but i think is the motherboard )...

the BSOD appared to me are all conneted with the video card , FX770M in this one... i think is that or the mobo...the same part.

 

solved...with dell nvidia driver all works fine.... with the nvidia driver downloaded by nvidia website... bsod and crash...

 

crash , only on power on , returned.... the led keyboard status connect the problem to a "A possible processor failure has occurred."

i've tray this m4400 with the original cpu and another cpu , problem with toghether...

i think is the motherboard......

 

my m2400 have the bsod problem too, only 285.62 and older nvidia driver work good, any newer driver all get bsod randomly
very strange....

 

I've just rebuilt my old m4400 with Windows 7 Ultimate and all latest drivers from Dell website and the user I've given it to reports that the touchpad freezes, it's done it 3 times today and can only be fixed by a reboot. Left and right click buttons still work. Any ideas?

And does anyone know where there's a list of Fn hotkey combinations, the "Setup and Quick Reference Guide" doesn't give a clue, or which the combination is for the touchpad.
