9500m GS Problems

Hello all, i bought a 9500m gs 512mb ddr2 about 2 weeks ago.

been running fine, i overclocked it etc, flashed the bios for a perm overclock, went back to stock clocks, was overclocking fine etc.

now i can't flash the gpu overclock speeds at all, restart just crashes and get bsod about nvdl.sys error.

i can only overclock a little bit with nTune.

now, after all different drivers iv tried, Dox 185.85, currently on 181.22, i run a game for a short time, stock clocks, i get all sort of dodgy stuff going on, pink sqaures, different colours, all messing up the gfx, i have to tab out to desktop, the display driver crashes and recovers, then i tab back into game, and its fine, again, then it crashes after a short while, any ideas?? you think the gpu is dying?

i opened the back up and the thermal paste wasn't making a connection very well, it very light and thin, and places was no thermal paste at all, could this cause the artifacts? my temps aren't going over 82 degrees tho...

any ideas what i can do? which are the best drivers etc?

many thanks.

 

Can you flash your 9500M GS back to original state.
I am surely it is not the drivers(whatever version) problems.
You did too much of flashing on the 9500M GS if not mistaken(you told us on another thread before).
Now, flash it back to exactly the original BIOS and setting of 9500M GS even the voltage.
Get the official 186.03 nvidia geforce driver(safest) from nvidia website. Install it.

 

Yea i've had the original BIOS on it for a few days now, i'll try the official driver thanks,

so could bad connectivity on thermal paste cause any problems?

 

Will undervolting it help me? ive never undervolted a GPU before, ive done the CPU though, its it just as easy?

 

LOL? You know how to flash your 9500M GS clock speed. Why you don't know to flash your 9500M GS voltage? Strange.
Undervolt is not very helping on those artifacts/buggy stuffs. Undervolt is basically to lower down the temperature.

Is it your thermal paste too thick? LOL.
Some thermal paste only takes effect after a few days or one week and during the period, it may give negative result.
Please do not apply too much thermal paste, it brings negative effect.

 

I've not looked how to undervolt, and yea i only flashed the GPU.

the thermal paste is not thick at all, it wasn't even on properly, it had gaps etc...
