Graphics issue I THINK
Ok so a few months ago, my 18 month old pc starts to just starts have a yellow haze across the screen and then freezes. After a few rboots it starts going to a blue screen saying something about the nv4_disp file. A bit of googling found that people with this problem simply updated their graphics card drivers. So I do this...after going to a site like crucial that tells me what my system has...a geforce 8400 gs. So I update drivers, to no avail. A tech friend then says try again but uninstall all graphics drivers, reboot then install again. This worked! Problem solved. But no. It last a month then happened again! This time I got my original paperwork that came with my pc so I could phone them and ask. On the paperwork I noticed it said my spec has in fact got a geforce 7300GT card! So guy on phone says I've probably installed wrong drivers, just now use the original disk, which btw I'd totally forgotten I had! So I do this..again, problem solved!! For a little while! Now it's doing the same thing again, I did the same driver reinstall procedure and this time it had no affect at all! Also, what is weird is that when driver is installing, my own pc is telling me the card is a 8400gs yet paperwork says otherwise! STRAAANGE! Anyway, am I to conclude that graphics card is just knackerd? Or could it actually be something else? Harddisk?
Thanks for any help.
