Hi all, just wonder what you all think:
I have a Gigabyte Radeon HD 7850 that always worked perfectly in my old machine, that two days ago, I took out from my old computer, to place into my fresh new build:
i7 4790k w/ coolermaster 412s
Asus Z97-AR
2x8Gb Corsair Vengeance Pro 2400
500 Gb Samsung 850 EVO
Fractal R5 Case
(temporarily, as taken from the old machine) a Coolermaster RS 500W psu (yes its old and cheap, but has always worked so far, running for several years in the old machine - an E8500 - with this same Gfx card)
Now this build has honestly been a problem child, on start-up initially I've had all sorts of problems, notably not always starting on "power up" at all (i.e. fans whirred but nothing on screen), then "Overclock Error" message on the start screen, as well as the computer rarely being able to restart itself, and a few occasions of cycling itself "on/off". First thing I did was to update the BIOS (from version 0702 to 0902), which then caused more problems - after "windows loading" message the screen would just go black again (no signal received).
I used a 2nd graphics card (a Radeon 4550 i had lying about) to get by into windows, and d/l the BIOS again to the latest version (that it hadn't done automatically the first time!). The latest BIOS fixed almost everything, including the overclocking error (I had realised this was due to incompatibility with the RAM under the first BIOS versions, as the bios wasn't recognising the RAM clock speed at all). It also fixed the power-up and power-cycling/restarting problems. I then went and fixed all the Windows issues I was having - all the updates etc I needed. The last problem was that a very old/untaxing game - ran very blocky, so then I updated the graphics card BIOS and drivers, which also seemed to fix that problem!
So after several hours of hassle and work, all was happy, an fast machine, running perfectly, problem free, and quietly for a day and a half.
Until this afternoon - I was playing said old (windowed) game and my display started flickering, faster then faster... and before I could close down the computer the screen went blank (no signal detected). Now on bootup it appears to work fine, windows logo appears on loading, but as before, screen goes blank instead of the desktop appearing. So I've been through the following steps to try to check it:
Radeon 4550 in the new machine works ok.
Running from Onboard graphics works ok.
Using split monitors (one onboard and one with HD7850) - works with onboard but not with HD7850 screen.
Placing the HD7850 into the old machine, I get the exact same problem (goes blank before desktop appears).
The gigabyte/ati utility programs don't recognise the HD7850
Device manager says the HD7850 is running properly.
So in all your expert opinions - is this a dead card?
If so what to replace it with? AMD or Nvidia as a preference for a midrange card.
thanks!
