So my laptop looks like this, and the squiggly blue lines are not a by-product of my phone's camera. http://yfrog.com/nelaptop1ej http://yfrog.com/n4laptop2gj About a year after I got this Sony VGN-FZ4000 I started getting BSOD's saying there was a driver failure. Less than a week after the BSOD's started the same squiggly lines appeared and my computer was unusable. I took my laptop into Sony and they fixed it covered under warranty by wiping the harddrive and I'm not sure what else. Last May the same squiggly lines appeared and I took my laptop into Sony. Unfortunately my warranty is expired and they want an obscene amount of money to send it in and fix whatever the problem is. I asked another tech forum back in June and there someone suggested that the problem was a fried GPU, but I couldn't continue to read the forums because I didn't have a computer (and also it was summertime in a college town, if you know what I mean ). Well I broke out my laptop today and I'm determined to try and fix it, whatever the problem may be. Currently it is running on Ubuntu OS. I tried installing Windows 7 64-bit but I believe it may be incompatible with my hard drive (there is an error message saying my partitions are incompatible when trying to install). When I installed Ubuntu I'm pretty sure I wiped the hard drive, but this was a few months ago so I can't be 100% sure. Any help is appreciated.
