Video: reinstall the driver. If problems persists, another videocard would be the next thing to try.
Boot into boot-menu: that's something you can reset with MSCONFIG, I think, or else with TweakUI.
Internet settings changing automatically: see what CWshredder and Hijackthis have to say about browser plugins. If it doesn't happen in Safe Mode some other running malware is suspected.
Hope this helps.
I need a little assistance with a computer I'm working on. It's a Intel Pentium w/MMX 233 with 72 m/ram and a ASUSTeK TXP4 REV 1.X motherboard. First it would only boot into safe mode; into normal mode would come up with a Windows Protection Error which I have fixed(??!!??). It will now boot into normal mode but I now have no graphics, only 16 colors. When I tried to into the Settings tab to check the adaptor, etc., it flips to a blank screen & freezes. I have to do a ctl-alt-del twice before it reboots. It always starts back up to the boot-in sreen with the options of how to start the computer. I've installed new software & done all scans, ie: AV, AD/SPYWARE, etc and cleaned it all up (it's my cousin's computer who has no fear ((which means he is oblivious to all the spam, etc out there, even after repeated warnings)) and downloads, chats & God knows what all else). Everything else appears to work, except the internet (lan), which may be a seperate problem (it also means I may have a newer virus that the software didn't pick, but I doubt that is the cause). I have also noticed that if I change any settings, such as "days to keep in History" in the Internet settings, it always reverts to default settings the next time I enter (that happens even if I haven't re-started the comp). Any ideas would be much appreciated. Lloyd. PS: could it possibly be the video card that started all this? Thanks.
