Angry does a driver can damage graphics chip?

After installing 180.18 driver my graphics card started to behave in a strange way - even when I have reverted to 177.82, strange behaviour remains:

* computer freezes for a couple of seconds (Xorg eats 91% of CPU) then X crashes, when it restarts, screen is full of random images / patterns etc. when I try to restart X (ctrl+alt+backspace), it shows damaged nvidia logo and hangs (power cut off helps)
* when I restart my laptop, I can see on POST screen damaged Dell's logo with red and blue patterns, then GRUB's screen is also incorrectly displayed with black patterns...
* in text mode instead of empty space I can see dollar signs...
* then when I want to start X, I get:

NVIDIA: could not open the device file /dev/nvidia0 (Input/output error).
(EE) NVIDIA(0): Failed to initialize the NVIDIA graphics device PCI:1:0:0
(EE) NVIDIA(0): Please see the COMMON PROBLEMS section in the README for
(EE) NVIDIA(0): additional information.
(EE) NVIDIA(0): Failed to initialize the NVIDIA graphics device!
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found
giving up.

I can switch off my laptop (and take out the battery), start it again after a few seconds, everything works till I login and start doing something - then it strikes back.

Any ideas?

I am using Fedora 10 with kernel 2.6.27.7-134 and 177.82 nvidia driver delivered by rpmfusion.org (akmod-nvidia package).

a the moment I have access to my computer using framebuffer (with vga=792 kernel switch), otherwise I can see only dollar signs in CLI (nv driver loads, but displayed content is damaged, it hangs after a few seconds too).

You could see if a LiveCD works.

it does load till a login screen where instead of the login screen I can see random parts of the previous images... etc. pressing enter should load live user, but it doesn't happen.

<DARKGuy> a way to know when a card is damaged is to go into the BIOS
<DARKGuy> go through the options (not changing anything) just to make the video card refresh
<DARKGuy> open up the system monitor and leave it for a minute or two
<DARKGuy> if you see artifacts at BIOS, then it's damaged.
<DARKGuy> BIOS doesn't use -any- drivers
<DARKGuy> it's barebones video
<DARKGuy> no way it can use anything linux/win in there
<DARKGuy> if the errors go -after- Linux's post, it could be a Linux issue
<DARKGuy> if the errors are when Linux starts booting (Grub/kernel loading) but it doesn't screw up in the bios, it could be either the card is damaged, or it's a linux issue
<DARKGuy> since Grub loads video too in kernel parameters

artefacts are visible in BIOS / Dell's logo (while booting), when I start X, I can see parts of images I've seen on my screen couple of resets before.

Two days ago I had kernel 2.6.28 with 180.16 installed and got this artefacts... then have downgraded kernel to 2.6.27.7-134 and nvidia 177.82 - it worked fine yesterday, today in the morning, problem re-appear when I started my computer after work today - at first, X restarted, then hanged. After restart I could see artefacts again...

if I see artefacts, I know the only way to get into my system, is to use framebuffer (kernel option vga=792) otherwise I will see nothing.

btw: when kernel is started with vga=792 option, no artefacts can be seen on the screen.

laptop was off for about 5 minutes, switched on, started, x started - can see part of the last screen of anaconda... so graphics chip definitely doesn't get reset when computer restarts...

so it most likely doesn't seem like a hardware problem (= broken hardware)

check the following 5-6 hits out:

(I'm not hoping that you've been hit by that problem cause I'm having the same hardware )

edit:

just read your last post

good grief !

I'd say RMA your laptop / let a technician come to you and exchange your motherboard with that chip

apparently my XPS M1330 works fine, I have this trouble on my Dell Latitude D620 laptop...

also, if I use vesa driver instead of nv/nvidia - X starts without any problem... though in 800x600 only (and no artefacts on the screen!)
