(GPU in question - Gigabyte GeForce GTX 660TI OC Windforce 2X 2048MB GDDR5 PCI-Express Graphics Card)


Hello everyone!

So I was letting my PC run a game and returned later on to find that both monitors were blank and the amber light was showing on the monitors rather than the usual green. Kept saying "no signal detected" when I tried to check the source.

I restarted the PC and changed to using one monitor with a VGA cable from the mobo to the monitor and that worked fine! I tried again with my main monitor using the HDMI cable (GPU to monitor) and a DVI/VGA converter thingy (again GPU to secondary monitor) and both still kept showing no signal detected.

When I changed it to use the integrated graphics on the mobo it was working fine once again and I noticed that the GPU is now not showing in the display manager and I can't even open the nvidia control panel. When I open nvidia inspector, everything is greyed out with no values/letters anywhere.

I checked the GPU and the fans do run fine when the PC is powered up and I even tried a different HDMI cable to check and that still kept giving a blank screen with no signal detected.

This base unit was purchased in Feb 2013 so I guess it's not going to be the most up-to-date!

""Titan 8200i Spinosaur" Intel Core i5 2500K 3.40GHz @ 4.40GHz DDR3 Quad Core Gaming PC". The PSU is the Corsair GS600 (600W) and has always worked fine!

Any ideas? Has it just bit the dust? I'll try provide more details if required.

Thanks
 
I rebooted my system and before I could get to the desktop I got a display from 'American megatrends' with all the CPU spec etc and at the bottom it said Overclocking failed! Please enter setup to reconfigure your system. press F1 to enter setup.' So I turned the Overclocking off and rebooted and kept asking if I wanted to start windows normally which I did then the screen stayed blank and kept saying no signal. both screen have been tested with the VGA connection and both say no signal.
 
that you can get the bios fine to me says the display is fine and so is the gpu, however i ithkn your windows install is done for, maybe the drive is on itsway out.

anyway to check either try a spare hdd with a quick install or if you dont have, try a usb live linux distro to confirm that the gpu and monitor are both fine and not the problem.
 
Thanks for the help everyone. I took it to a shop, turns out the PSU and GPU had both failed. It's now got a 650W PSU and GTX 750 Ti fitted.

Just manually raising the OC on the CPU again now. The i5-2500K was OC'ed to 4.4ghz on purchase but I've set it to 4.0ghz for the time being whilst I tweak the CPU voltage and VCCSA as I've been getting some 0x124 BSODs from it.
 
I wonder did someone take you for a mug at the shop....it's incredibly unlikely that both GPU and PSU were both dead, and a 650W for a GTX750Ti is mad - the 750Ti runs on a 200w supply just fine.
