7900gs .. green lines of death?

post #1 of 12

Thread Starter 
So I've had my 7900 overclocked since the gtx/gsx bios thing came out a year or so ago. The other day the laptop's screen was frozen and it was locked up. Rebooted and had vertical green lines on the screen during bootup and black screen at startup.. had to reboot into safemode where things worked.. uninstalled the driver and it rebooted back into vista just fine. Installed a new driver and things seemed fine.. green lines were gone and windows worked.. the next day I rebooted and green lines are back... and things not working again.
Anyone have experience with this? I would like to reset the bios back to the original 7900gs at the stock speeds and voltage.. but I can't find the original bios.. and when I try to load any other 7900gs bios's I get a "bios mismatch" error.. with nvflash.
Any help would be greatly appreciated.
thanks

Check the sticky here on Over clocking your 7900, the CD ISO file has a stock ROM included, along with directions.

What are your temps GPU and CPU ?

that gs+gtx = gsx bios sticky was the same iso I used to overclock a year ago... but the iso isn't available anymore, i get a 404 error when clicking the link. Is it located anywhere else?
My temps I'm not sure where to find... I'm using vista.

overclocking shortens the life of cards.

Looks like I'm having the same problem as you except I'm in XP and the lines are broken up not straight. Removing the driver from safe mode allowed booting back into XP. few days later the lines disapeared so i reinstalled the driver and all seemed fine but then the distortion came back. Unfortunately I've had my card set at stock speeds since day one so I don't think flashing back will help you. (but try anyway) I've tried just about everything to fix this and it didn't work. I ordered a replacement go 7900 off ebay and should be installing it tommorrow if that fixes the problem I'll let you know cause its either the card or mobo.... i hope its the geforce...

Unfortunately replacing the video card didn't fix my problem. Hopefully our issues are different.

That really sucks, pretty much accepting having a crippled laptop after not being able to resolve this problem either.
If there's anyone out there who has resolved a similar problem.. let us know.

mentaldelusins.. have you tried connecting to an external monitor?... exact same deal?

Also I am still having trouble loading a 7900gs bios... I keep getting "bios mismatch" error. I can successfully load any 7900gtx bios. None have worked any better. I really want to get a 7900gs bios with a 1v voltage. All of the gtx bios's are 1.24v or more.

hookin to external monitor is the best thing for troubleshooting. Try it and see if it persists, then report back

I tried plugging into two different crt monitors to see if it was a problem with the monitor but they displayed "Signal out of range." I plugged into an LCD monitor and it would display the image but still showed a "Signal out of range." box bouncing around even though it was showing windows in safe mode (still distorted.)

So for some reason I can get it to work for a while...
booted into safe mode.. uninstalled the driver, then used "driver sweeper" to uninstall drive(clean driver). Then rebooted normal(still green lines)... now I install driver(101063).. continue to install even though wdm driver is being installed automatically by vista.. takes a while.. then restart and bam.. green lines are gone.
Ran 3dmark05 got an 8500.. everything worked fined till later I ran a .wmv and it locked up... restarted and green lines again and wouldn't completely boot.. had to start process all over again.. and now again working.. Oh yeah , while running 3dmark05 I picked up the laptop and shook it around and tweaked it just to make sure it wasn't a physical hardware problem. Oh yeah.. once when playing a video it locked up temporarily and got a "driver not responding..restarting" (or something like that)error. Darn these inconsistencies, bugs the hell out of me.. a computer should be straight forward.. either work or don't work.
Well.. hope this helps..
