Black screen startup 8800 gts
« on: February 09, 2014, 05:50:09 pm »
I have a prob,whit a geforce 8800 gts 512mb.

I got it from a secondhand site and all was alright till i started to overclock

Nothing big,oc at 16% and the temp was 60*C wich aint so high.But when i started the pc next day,i got only black screen,no bios no safe mod no nothing.

I have a
pentium D 805 2.66
gigabyte ga-8i945pl-g as mobo
500 mb ram drr II/ 4 slotsX 500=2gb
acopia dual fan it-25f2 -psu

I know the mobo aint dead cuz i tested with my other gpu,and it worked
Did a bios reset-still black screen
changed the ram position
tried with other monitor
dvi-vga adapter works(i tested on the other gpu)
Nothing worked

I noticed that now when i start the pc,the gpu fan speed doesn't change i mean its at 100% but when i had a image on the screen at the start up,the fan speed was at 100% only for 3 sec,then it changed lets say at 50% after those 3 sec.

should i try the bake fix or its a certain dead card?

Sry for my spelling mistakes hope u can give me an answer cheers.
