That i7 should have onboard graphics so I start with that as a test.
Normally I tend to spend alot of time and figure out these things on my own, But this has baffled me as to why my graphics wont work. My Current Build :
Case: Thermaltake Core V21
CPU: 3.40 gigahertz Intel Sandybridge i7-2600K Unlocked Core i7 Quad-Core Processor Socket 1155
GPU: Asus Nvidia GeForce GTX 750 Ti Graphics Card
Mobo: ASRock B75 Pro3-M
Ram: Corsair CMZ16GX3M4A1600C9 Vengeance 16GB (4x4GB) DDR3 1600 Mhz
And 2 Hard drives (cannot remember spec)
Windows 7 64 bit
Hanns.G Hi221 [Monitor]
Ok I know alot of the parts are old nowadays but it still is or was a really nice system running !
So Previously this system built was in another old Case but INSTEAD with Mobo H77 Asrock/ Nvdia GTS 260. It Ran fine for a good few years , then my display output started playing up one day, so as I just assumed it was the Graphics card, I simply bought the 750 TI last year & replaced it , it seemed to work perfectly fine after. Please note the 750 TI was connected to the monitor via VGA, not DVI through an Adapter like the GTS 260.
Situation now :
Now a few months later, and something similar seemed to happen where It just failed on me again but this time with the new GTX 750 Ti. I also had various times where the power would just cut off , which was really weird .
As the case was old I thought maybe there was alot of dust or something was shorting with the mobo & failing to give power . As I had a new PSU and a not so old Mobo, I tried getting a new case .
And Again Graphics card not working,
If I connect the graphics card with power , the green light is on & the fans are working , so i know it is on. But the monitor will not show any signal.
I tried with it still connected but instead the monitor connected to the onboard graphics & again no signal.
It is only when I disconnected power from the GTX card that I get signal from the onboard graphics.
I thought maybe it could be the monitor itself , but that works perfectly fine with the onboard graphics.
So in conclusion Ive tried a new Mobo, New Case , ive tried a different power supply.
Ive tried the Old GTS 260, as well as an old back up PCIexpress graphics card.
Ive tried connecting the Graphics card via HDMI to a TV as a different source of output.
Ive tried this program called DDU to clear all drivers & reinstall Nvdia latest.
As the GTX 750 TI is only 7 months old & hardly used when purchased , I would like to think that it isnt the problem, but im not totally sure.
Only thing left I might try is to reinstall Windows , but I thought Id ask you guys first if you had a solution .
Very much appreciate any help !
