    Hi,

    I know some basic stuff about computers, but I don't know how to fix this problem.

    I have Windows XP. Firstly, the computer started running slower than usual for a while (a few weeks), then one day when I started the computer up, a screen came up in the DOS bit at the start asking me what mode I wanted to start in as there was a problem. I selected the option (and Im paraphrasing here) 'The last good configuration' as it seemed best. From then on, the colour went to 4 bit, and an 800x600 resolution. I can't change these settings as I normally would, as there are no other options available. I can use the computer fairly normally, except the awful colour and res. However, if the screensaver comes on, and I re-activate the screen, it will be totally messed up - the edges puffed out like a pincushion setting, black and white, lines travelling down the screen and flickering, sometimes going totally black then coming back again. :eek:

    My housemate started the computer up and somehow got the original DOS screen back asking which mode to start in - he selected 'safe mode' and the colour was then good - except the internet then wouldn't connect. (I have broadband so it's normally automatic - I don't know how to connect it manually)

    This is my brother's computer, so I don't know a lot about it - programs and so on - he's un-contactable at the moment and will be for a couple of months... I'd greatly appreciate any help!

    Many Thanks.

    By the way - I don't know if this is relevant but the computer does have a firewall.

    to connect to the internet in safe mode you have to select safe mode with networking

    But sorry thats all I can offer at the moment

    Wintersun,

    If you'll RIGHT click on My Computer and choose Properties, then choose the Hardware tab, then click on the "Device Manager". When the list opens, you'll probably see a big yellow " ! " next to the Video card listing. This means that your video card has failed for some reason. As Dai said, reinstall your video drivers for this card. That may solve your problem. In the meantime, the system is running off the bare minimum video on the motherboard, most likely. That's why you cannot go to higher resolutions or better color bit quality.

    Luck!
