7805u can't game anymore?

I bought a refurbished 7805u last year. Recently, I have been continously attacked with the nvlddmkm.sys crash every time I've tried to play any game whether it'd be League of Legends or Team Fortress 2. Invariably, in fifteen minutes or less, the game will crash with GPU temps at about 80 C. Strangely enough, sometimes my laptop will just function like it should for a while, allowing me to play games without any crashes. However, it would soon just being crashing again within a week.

I've tried many fixes for it, ranging from updating my BIOS to 9.c.0.25 (had errors with 9.c.0.17 as well), updating my GPU drivers to Dox's latest versions, forcing performance 3d in rivatuner (this just causes crashes outside of games as well), flashing my GPU BIOS, disabling Powermizer, various registry tweaks, elevating the laptop (helps a little bit but still makes games unplayable with way too many crashes), basically every thing I could do without actually opening the laptop itself.

What should my next course of action be? Open it up (or get a friend to open it up for me) and apply ID7 and clean dust? Or is there no real solution for my GPU is dying and I should just get rid of it while I can?

Thanks.

 

I would say clean the dust first
It should drop your temps by at least 15 degrees Celsius

btw, you do not have to open the laptop up if you don't feel comfortable, just spray both fans from different angles.

 

What I would do is test to see if it will crash at really low temperatures like 60C. What you should do is underclock the GPU and/or limit the FPS in a game to something low and try playing like that. Its funny you mention League of Legends. I had a graphics card freezing issue that would happen in any newer game like League of Legends but only rarely for Dota Allstars (War3). My recommendation: play Dota Allstars, its better than LoL. Ok, but a good last resort thing: flash somebody else's video BIOS. I'll tell you how I solved my problem. My laptop was under warranty and I shipped it for repairs and they had to replace the whole motherboard (probably due to the idiotic soldering of the video card.) Did you say that it crashes outside of games? If not you could always sell it as a non-gaming laptop or use it that way. Here is a program that is infinitely better than powermizer switch that you should use for testing: PowerMizer Manager | Some More Bytes I guess though you have already done it with rivatuner where you undervolted to .9V.

 

One more thing: do you get BSODs or freezing?

 

Freezing into a black screen that doesn't ever end.

My computer HAS crashed in War3 before.

My computer sometimes does crash while just browsing the internet too.

:\

 

Change your OS or reinstall a new fresh OS

 

It doesn't sound like a hardware problem since the BSOD's are crashing because of the nvidia driver. Have you made sure that you completely remove the files by going through Device Manager instead of simply installing one driver over another?

 

Heh, I've got just the thing for you

Yes.

Already did it.

 

Today my laptop flashed to a black screen.

I still had music on and could hear it but I couldn't see anything.

Is this a sign of a dying GPU?

 

It definitely sounds like your GPU is withering away. I had the same problems with an HP laptop that died half a year ago. It started acting just like yours. A few weeks later, Windows Aero was permanently disabled and any GPU intensive application would crash it. Every time I booted the laptop up, "$$" signs would appear in columns.

 

try either new drivers, open up the laptop to clean the gpu, and reformate the hdd.


If none of the following works, its time to look for a new laptop. Andros's flash worked for me, before I flashed it. I took my laptop apart to clean it. I found out a quart of my gpu's heatsink was covered in dust. I also applied termal compound on the gpu and heatsinks. It bothers me gateway decided not to put compound on the ram when its running at that high of a temperature in an enclosed area.

Try doing that before you buy a replacement. Just follow the guide posted eariler you would be able to do it yourself. I was in a smiliar situation before.

 

I'm more inclined to believe it's this particular laptop. Two of my friends bought this laptop as well as myself and we ALL had to get it repaired. I was having identical problems to yours, nearly. Each time I played anything that heated up the laptop it would totally crash. This happened rarely and steadily became more common over the course of a year until it was unplayable. I had to have the motherboard completely replaced and I haven't had a problem since then.

While I'm here, I was wondering if anyone knew a particular cooling unit that worked well with this laptop. Also, I was wondering if anyone knew the best way to go about cleaning out dust from the fans.
