So a couple of hours ago I decided to finally clean my PC from dust. Not my first day using a computer and maintaining it so I know the drill and was very careful with that. After I was done I turned it on found myself in situation where my screen won't turn on. As if it's in stand-by mode.
I noticed 3 red lights blinking on my video card ( radeon hd 4870 )
D1601, d1602 and d1603 - after googling it.
The cooler is working, my card doesn't seem to overheat, I've already repluged it a couple of times but still the same effect. I got both 6 pins connected, but the card doesn't seem to notice 'em.
Even tried taking out the CMOS to reset Bios.
I guess I did screw up somewhere alomg the way, I just can't figure out where...
So I'm out of ideas...
Would appreciate any help.
