Probably not the right place to put this, but I am unsure if this is a graphics card related problem or a (boo, hiss) itunes related problem.

Long story short, I built a comp for my girlfriend from bits of my old PC, a tri-core phenom 2 720, Gigabyte GA-MA790XT-UD4P (i think, off the top of my head), 150gb velociraptor and 500gb HD, a single dvd-rw, Nvidia 8600gs (first nvidia I've used in years) and a corsair 430 system builder PSU, running Win 7 home basic 64 bit. No problems whatsoever until yesterday.

Girlfriend has an Iphone 3, and has upgraded to a 4s. Bloke in shop says back up 3, restore on 4s, and all will be well with the world. Tried to back up the 3, it failed miserably, stating it had been disconnected despite the phone saying sync in progress or some other nonsense. I eventually after a few attempts got it to back up, however for some reason on a few attempts the monitor shut down as if the computer had gone to sleep, but wont wake. Frustrated, I went in to power settings and turned off every sleep option there is, and went to update/backup and restore the phone.

Half way through the back up, monitor turns itself off, wont wake up. Restore seems to have worked however so restarted the computer and tried to set up the 4s. Half way through the restore, monitor turns itself off. Iphone seems set up so left it at that.

Any ideas what could be causing this? It has only ever happened while the Iphones are connected, surely it can't be overloading the PSU and shutting down the graphics card?
 
Pretty obvious that's what happening! Try connecting one iPhone at a time. They draw quite a bit of current when they're fast-charging. You could try charging them both to 100% before you do the restore.
 
Bringing this back as I've upgraded the PSU to a Seasonic 750w, and the issue is still there, without Iphones connected. After installing the PSU, I then updated a few programs, and while updating Itunes, the same thing happened. Screen goes black and turns off, computer is still on, but does not respond. Almost as if it is putting itself into sleep mode. As far as I am aware this only happens with Itunes is running, and I am completely stumped, have no idea what could be causing this.

Any ideas?
 
Tried both. But as I said, it's also doing it without the Iphones plugged in. Only things plugged in when it last did this was a mouse and external (powered) HD.

Only thing I can think of is it being a dodgy graphics card? It's only a £25 jobby so not a problem to go get another and try, would be just my luck that I buy an Nvidia card for the first time in years, just to be sure on its reliability, and I get a duff one!
 
Will almost certainly be having another go over the weekend, anything else I could try as well as the change in graphics card that might improve matters?
