Hi there,
I have a relatively new ACER Predator G3620 which came with a Radeon HD7770 video card. I've just bought a GTX580 Twin Frozr II to replace it. As a bit of a newbie I think I've made a bit of a mistake installing it. I opened up my computer case, took out my old video card, and put the 580 in it's place, attached the DVI lead to my SONY TV (which is the only monitor I have). The computer loaded up fine - and a low resolution picture came up. The drivers were out of date on the disk as I have windows 8, so I had to go on the net and find some up to date ones. During downloading the driver, the PC then crashed/restarted itself. When it came back on there was no video at all, just a black screen. Extremely frustrated at this point after pressing the power on/off button to try my luck a few times, still just a black screen, infact it doesn't even say 'no signal'. So I then put my old card back in (Radeon HD7770)(I originally used a HD cable to my TV with my old card) THERE WAS STILL NO VIDEO. What makes it even worse is... with all the Predator models, the manufacturers have disabled the normal VGI port for the dedicated on-board graphics. So I can't even just use an old VGI cable n hook it up to my tv to install the drivers and see what's up with my video cards. I don't know what to do! It's extremely frustrating having just a black screen when the PC is booting up just fine, all lights blinking, fans working, and everything running smoothly as normal. JUST NO VIDEO! :mad: Please help! :(
I have a 500W power supply
8GB RAM
i5 Processor
