Okay, I am in completely over my head with this one. I've googled this but I can't make any sense of anything that it's told me, so if anyone could help explain how to fix my computer, bearing in mind I'm pretty illiterate when it comes to computers, I would be really, really grateful. Also, I realise I've probably been doing all the wrong things to try and deal with the problem and that I've probably made everything ten times worse, so please don't think I'm an awful computer abuser, I have no idea why I did some of the stuff I did when I was trying to get it working again, I just am really desperate to get my desktop back. Every time I log onto my desktop it freezes then gives me a blue screen, sometimes saying that there has been a paged fault in a nonpaged area. The computer is a couple of years old and pretty rusty, I haven't ever installed antivius onto it, I'm trying to now but I can't start it other than in safe mode and it isn't letting me install anything onto it. It's also just restarted for no apparent reason upon startup while I was waiting for the BSOD so I could type out the details. I always pull the plug when it goes to the BSOD, so I don't think it's ever actually recorded a crash dump. This is on the BSOD, I thought it was a virus because of the fact there is no protection on the computer but I am starting to realise it's a genuine problem. Then the instructions, which I have no idea how to follow - I have no idea what most of that means - I tried starting it in safe more, IE opened about twenty times but I think that's to do with a virus. I followed the instructions on the MS website, but then I realise that it was for XP. What it said to do I'll paste here, I can't yet post links. I got to step 12, but the command prompt kept saying that the file wasn't found and I checked back and realised that it said XP, not vista, so now all I've done is mucked up the display as well as everything else, but I can't reinstall it so everything is being displayed massively. If anyone could also tell me how to re-install the drivers for my screen as well as what the BSOD means and how to fix it, I'd be most grateful as well. I'm really, really sorry if I'm coming off ignorant, but it's because I am. I don't know what drivers are or what BIOS is or anything. I really, really tried to fix this myself, but all I've done is make an even bigger mess out of things. I haven't just given up straight away, but this is driving me crazy and I really need my desktop back. edit; Just started in safe mode, according to the device manager the driver for the screen is still installed and up to date, but when starting in normal mode the screen is displaying weirdly and and not as it normally does. It also says that it can't display the status of the screen while in safe mode - does this just mean that it will go huge again if I boot it normally?
