I just finished remodeling my gaming pc today by adding a few more better things of which one of them was an additional GTX 260 so i can run my system in SLI. But right after windows installation was succesfully completed and my desktop was been prepared, the pc froze for about 45 minutes which made me impatient and went ahead and pressed the power button to restart. But the problem is that since then, both of my cards are no longer powering up and the fans are not spining. I dont know whats wrong and I;ve tried a few things which have already failed and I just wish that my cards are not fried up. Please somebody help me!!!!!!!!!!!!!!!!! with this problem!!!!!!!
my PSU is the Corsair 850. running on the evga 780i mobo with 8gig XMS ram and four 500GB hardrives. My cpu is the Q9400.
The thing my PSU is still running everything else including the two pumps for my two liquid cooling loops. but my GTX 260 just wont run.
so I just got back from the campus and did as you sujested but still not even the old card was running. So I tried my old 9600GT and it ran but no signal was been sent to my monitor. My 9600GT still runs by the way.
So I thought the mobo might have something to do with it and I searached for my old 730i and hooked it up and both the GTX 260s appeared to be running just fine.
so do you think something might be wrong with my 780i mobo or what?
Your not telling us what else you did in your case today. You said remodeling ? An added one new card. Did you have your cpu out, or your motherboard out ? If not, maybe the board had some kind of failure when you first started with 2 cards? Why ? some kind of load that was not there before ? Sometimes its helps whether its cars, or computers you change only one thing at a time. Good luck.
Ok. in that case, this is exactly what i did.
OCZ 600W PSU
8GB XMS ram (still same)
780i mobo(still same)
3 Carvier 320GB Hardrives
Coolermaster 590 case
Q9400 CPU(still same)
one GTX 260
Coolermaster 850W PSU
added 1 more 500GB Carvier
Antec 1200 case
added one more GTX 260
These are the basic important things i changed( besides all the numerous bay devices and stuff).
but anyways, i did some extensive research today after trying everything for the whole day and found out that am just one of the thousands who have already faced this type of problem with the 780i mobo either after windows installation like me or just after some other times.
Everyone says the mobo has a problem from manufacturer's making and is probably fried up or BIOS chip is now trash.
I tried my GPUs on my old 730i and confirmed they are just ok.
So basically,,,,ma screwed and need new mobo!!!!!!! and am broke!!!!!!!!!!
