I bought a new graphics card, and new Corsair Vengeance DDR 3 1600 ram, 4 gb x2 latency is 9-9-9-24. I already had 2 x Transcend DDR 3 sticks, latency is 9-9-9-11. Both are 1600Mhz.

I installed the new graphics card (gtx 960), then I removed all my ram, then put them all back in, both the Corsair and the transcend. I then switched my PC on and it went into a boot loop. I then read some threads, took my CMOS battery out and drained the power, reset it and then tried again, I even took the Corsairs out and put it all back together as before. Only now the PC boots but I only get the first screen (Bios screen) that you can press Delete to access boot menu, but it does not move on, it freezes there till it goes into a black screen.

I have a i5 3470, thermaltake 450watt PSU, H75 gigabyte motherboard.

Please help

Sorry I have a GA-B75M-D3H motherboard, and I would liek to run the PC with all 4 ram sticks.

Maybe the power supply fails when the pc tries loading Graphics after bios, seen lots of thermaltakes at that watt fail when they have to run pcie graphics as well. they get unstable. Exactly what model do you have?

Hi Mark, thx that might be the reality. I just bought the power supply. Its a Thermaltake Litepower 450W W0408 model.

I put my old gtx 550ti graphics card back in and it boots in to windows so I guess its the graphics card. I specifically bought the gtx 960 as it stated it only needed a 400W power supply. Dont know what to do

Can you test the machine with another psu and running the 960 or try the 960 in another machine. Elimination is key

Unfortunately not, I just got the model number of the PSU, its a TT-LT450. Also read forums saying its dicey with that PSU. But I am going to try get it going again.

I dont understand this PSU story, it came with a Pci 6 pin and it should be able to run the card.
