Hi everyone, This is my first post to this site so hi to everyone! I hope someone more knowledgable than me can help me out - I'm a bit of a novice when it comes to these things. My system comprises of an AMD Athlon 2400+ cpu, Asus A7V8X motherboard with 1 gig ram and a Geforce TI4600 graphics card. The other day I switched on my PC to be met with a blank screen just after the windows XP loading screen. I rebooted into safe mode and noticed some weird green vertical lines kept appearing. I removed and reinstalled my graphics drivers and all seemed ok until then next day when I had the same problem. Basically it kept getting worse until reinstalling the drivers had no effect - now I can only boot up windows in VGA mode or with the drivers uninstalled and even then I get strange lines/objects on the screen. I even get them on the initial black and white boot up screen. If I hit F8 to go into safe mode I get these weird green blocks on the screen too. Am I right in thinking my Graphics card has keeled over? Apologies if I've just asked something daft!
