gunslinger1 Posted December 23, 2008 Report Share Posted December 23, 2008 Approx. 4 days ago , playing Doom 3, screen became pixelated then went black and had to do a hard reboot. Upon reboot screen pixelated with random lines and colors on the screen, then black again. Tried installing OEM video drivers................same problem. Nothing I did seemed to solve the problem. So since I had stored important info on an external HD, I decided , since it had been awhile, to do a full system restore and guess what...............same results ! So now I'm thinking the video chip, 7600 go, has taken a crap and started searching the net for any news I could find. After talking with a local comp. specialist, he informed me that HP had extended the warranty on certain models of their notebooks using "Nvidia" chips to 2 years (of course my notebook was 2 years and 1 month old). Also came across an article that stated Nvidia admitted they had shipped defective chips to pc manufacturers (though they would not disclose which chips). http://www.engadget.com/2008/07/02/nvidia-...s-are-defectiv/ So I decided to give HP a shot, since according to "THEIR" forums, many people were having problems with Nvidia chips ! http://forums11.itrc.hp.com/service/forums...hreadId=1274587 I was told that my model was not part of the recall but..................... that they had good deals right now on new notebooks :) To which I replied "I would be spending my money on a Non-HP notebook with actual "Video Cards" ! Anyways, while in safe mode, I finished the system recovery and decided to try one last video driver, since the OEM driver was not helping me at all, and installed 156.55, that I had found on softpedia, when I go into device driver it's listed as 6.14.11.5655and bingo, everything boots up and runs.................no problems, except one in awhile the screen will pixelate for a second or two, then return to normal. Right now I'm at a point where I'm afraid to change anything (drivers) or to even load a game. My questions are: 1. If I'm able to finally boot normally, does that mean my Video chip is fine and that this is a software issue? 2. I was using a driver I downloaded from here about 9 months ago, I believe the Bioshock drivers, lost version when I did a system recovery, that had worked fine. Could these drivers had become corrupted ? 3. I have noticed twice, my desktop pixelating for just a second or two and then returning to normal........any ideas ? Thanks for any input !

Andrew55 Posted December 23, 2008 Report Share Posted December 23, 2008 This looks almost definitely like a failed/ failing gpu. I will be able to confirm this if you can post a screenshot. Additionally, the gpu's that 'failed' were the g84 and g86 series, not yours so your own, as you rightly stated was not part of the recall. And finally what are your gpu temps?

gunslinger1 Posted December 23, 2008 Author Report Share Posted December 23, 2008 (edited) Then why is Hp recalling 7400 series chips and everyone on the HP forums talking about the 7 series being defective. Haven't had a chance to check temps since system recovery. So either way my gpu is toast ? Even though I'm up and running now ?

Andrew55 Posted December 23, 2008 Report Share Posted December 23, 2008 Are you sure it's 7400 and not 8400? And when you mean up and running is this without problems. Quote Link to comment Share on other sites More sharing options...

The HP rep I spoke to said the recall was for the 7400. And yes I'm able to boot up normally....................finally! But, I have noticed, in a 12 hour period ,my desktop artifacting, pixelating for a split second, twice , then returning to normal.............Driver maybe ? Did a full system recovery, installed latest driver, from HP to no avail. Was not able to boot normally until I install the driver I'm using now, 156.55 !

Andrew55 Posted December 24, 2008 Report Share Posted December 24, 2008 I'll still need to know your temps to confirm, you can use ntune to monitor them. Quote Link to comment Share on other sites More sharing options...
Andrew55 Posted December 25, 2008 Report Share Posted December 25, 2008 By the way the title of this thread sounds like it could be the title of a novel. :) Quote Link to comment Share on other sites More sharing options...
