Sadly sometimes too deep. While we can mention SFC SCANNOW (see google) you need your CD to do this. Maybe this is the time to fix that or go get Windows 7.
Dell has diagnostics so try that.
I got a malware which caused my computer to crash . It was removed, now it free from viruses and malware.I have a dell dxpo51 with windows xp. My computer crashes now, and I get the blue screen. I ran a winbg and it might be caused by my video card driver, so I went to dell and downloaded the most current driver. It still crashes. The guy who got the malware out said it could be caused by aol being so embedded in my system. I got off aol about 2 months ago and got wireless, then shortly after is when I got the malware. I deleted their files after he told me that. That is when the trouble started. They took over my internet explorer. When I deleted their files , I must have deleted something I needed. I crash when I am on the internet. I switched to firefox, thinking that would help, but same problem. If it is my video card going bad or missing files, how can I tell. I don't have the recovery disk that came with my system. How do I know whether my hard drive isn't going out instead. The guy said I needed to start fresh, but I dont have a disk. Is there an easier way?
