Screen keeps going black and fan goes to 100% [Old rig]

[AngleTheReapto]

Hello, I am new to this forum, So I don’t know the protocols or what to do etc.

I have a problem: Whenever I open a game like GTA or something else that is GPU intensive, The screen just goes black, And the GPU fan goes 100% (4100RPM i measured with a tachometer). I checked Event Viewer to ensure something isn’t wrong with my drivers/software, but nothing to be seen.

I have tried everything in the book; Fresh installing Nvidia drivers, Trying different OS like Ubuntu and Windows 7 etc, Lowering down settings in games, Limiting VRAM usage, Under-clocking my core Hz from 980MHz to 800 and memory also by a -100MHz, Checking temps (only gets up to 70C which is normal on a FE).

I must admit, My card (A Founders 780Ti) is 250 and my PSU is only 550W (The issue I think is also by the CPU i7-3970X

also another ~200W)

 

Because of this concern, I did a mad lad move and installed a secondary PSU externally and jumping the green wire on 24-pin with ground and connecting both the 6Pin and the 8Pin required only to the secondary PSU and the other reserved for the Mobo, CPU, etc..

However, This had no difference on the frequency in “crashes”. I had lost hope and  tried the last resort, Changing the thermal paste (Even though core temps were ~60C, the air and the PCI back plate measured 80C using a Flir IR camera)

I used Thermal Grizzly Liquid Metal, And has not made a difference.

 

I think the situation is something to do with the card itself, So I contacted Nvidia, But they couldn’t help. Any help here would be greatly appreciated as this is my childhood rig from 2012-2013 and I need it back. Any experiences or thoughts, Please drop it down in the thread. Thanks to all.

Also, The case has another Mini ITX PC inside it, But it has nothing to do with the actual rig below (The one in question)

People who are interested, the specs are:

i3-3250 @3.5GHz

2x 2GB DDR3 1333MHz

asus p8h61-i r2

Nvidia GTS 450 ( My first ever card )

/\ has a pci-e extender as it wont fit

Howdy and welcome

 

have you tried a different gpu in the rig?  Parts go bad over time.
