thanks for the psu calculator link, Thanh55. edit: according to it i need around 690W. I though that as i only have one graphics card that 600W would be enough but it's the manner in which it crashes that first made me think it could be the PSU. Ive tried several different GFX drivers and also win XP,Vista and Win 7 but it's the same result every time.
if you are using the newest drivers, you might try knocking back a step or two, see if that fixes the problem. otherwise, sounds like a bad card, psu, or mobo like kyocera said.
That PSU has 48A; and is certified for Crossfire. It's more than enough powerful to power your PC. (if you follow such calculators than you need, according to the results, a small nuclear reactor to power a dual GeForce 295 system).
If it passes a Prime test, then wont be your CPU, which would be next fault after gfx card, I would check the drivers, however my brand new out of the box GTX 260 is having issues with nvidias 190.64 drivers atm, and im currently in the process of trying older drivers. You could have a motherboard fault, however I would have thought this unlikely. Why not try reinstalling windows, or maybe using another hard drive with windows on it, and a game, see if that works? I use an old IDE hard drive to test for errors once in a while. Just put your windows basics on it, drivers etc, and then run the game, see what happens. Sorry his some of this is a bit ramble-ly, like I said, I'm in the middle of my own pc problems, haha
use the warranty.. let them deal with it- you could try poking around in the bios, load defaults and reset configuration, see how that goes.. sounds like the memory or memory setts isn't getting along with the mb from what I've seen also happens alot when your ocing and pushing the memory past it's limits.. passed prime, you paid them the bucks for the warranty- let them narrow it down
yep,do you overclocking or want to do it?if you want to do overclocking,you need to make clear how much your system need power,for escaping system burned.
Thanks for all the input folks. I have found out there is a problem with my new mobo (Asus P6T SE). I have 6GB of memory but the bios is only showing 4GB and after testing the memory i found the problem probably lies with the mobo as the A0/1 Dimm slots which dont recognize the memory. It also might be be i7 920 CPU that is the problem because this contains the memory controller but it's more than likely the mobo. So what i was thinking was that because the GFX card shares some of the system memory (am i right?) and there is a problem with not all of the memory being recognized then that is why my PC suddenly reboots whenever i try to play some of my games(Always happens to PhysX games ). Cheers, Marc.
what else are you doing to narrow it down to the mobo? did you move the sticks to make sure it wasnt a bad stick?
hi, yeah i moved the memory sticks around and tried every combination/position possible. I know for sure its not the memory and it is the A0/A1 DIMM slots on my ASUS P6T SE mobo. Has anybody had experience of faulty memory/dimm slots causing their games to crash? Cheers, Marc.
Considering that the motherboard is under warranty and the whole PC with it, why don't you ship the whole thing for repairs??
yeah dont worry, the tower is getting sent back and the mobo will have to be replaced. I don't think a fault like that can be fixed.
