how can a bad or faulty psu affect a graphics card,i have had alot of trouble with a gigabyte gtx 560 ti oc card,noisey and crashing in some games,returned it twice to gigabyte warranty,second time they gave me a new card,but still had some crashes and i reduced the clock speed from 900mhz to 870mhz,this helped the stability,but a month or so later when i started my pc it made a loud noise from the fans on the card and had no VGA signal,i returned it and requested a replacement of a different brand,(gainward)hoping to avoid the same issue again with the gigabyte card,the store says it could be mt psu,but i am unsure.. my system is new,here is the specs..any help is much appreciated..thanks

Weird the Antec should be more then enough, Maybe a bad PCI-E wire it happens if not it is a Power supply issue at least it would seem that way. When you first turn on a PC it runs at full power and if the card is not getting a strong PCI-E connection the fan will most likely run at 100%. Their is also a chance it could be a motherboard issue, Like bios, or hell even wrong ram settings such as voltage asrock boards can not set the right voltage for ram. I got 2 asrock boards and both messed up the right settings for ram

A faulty PSU can cause all sorts of weird problems.

Try to borrow a good 500 watt PSU to test with. If you do not have a lot of components, in the case, a 500 watt PSU is all you need.

the fans on the card seem fine when i first turn on the pc(idle speed/quiet)its when i run games that it gets noisey,and have had some crashes when running BBC2(bad company 2)it was a few days ago when i restarted the pc from sleep mode the fans made a loud noise,and had no signal on monitor,rebooted a few times but had same problem,so i returned it to the store again

Unless bad drivers. I mean try running GPU-Z and check out your temps. on your card i can't believe it would be overheating. You are using the latest drivers right.

I'd say to try Nvidia latest drivers and did you watch your temps during gaming what temps are you getting. I had 2 asrock boards before and each one keeped messing up becease the ram was on the wrong voltage make sure you check that. Ram can do this to like not starting up during sleep or what not.

Best thing you can do is test test test. Get a different PSU to test the system, borrow one of a friend etc...
If this doesn't solve the problem you need to run some stress tests on your graphics card, I recommend furmark, see if you get any BSOD or crashing.
Thirdly test your RAM for stability, memtest is your friend.

In addition check that your ram is running at the correct voltage...

Bad thing is not everyone has a different PSU. I would say run prime 95 and Furmark at the same time and see if the computer restarts Also he should monitor temps WHILE gaming.
