hi,first time user so bear with me. Just installed new cdrw liteonit also USB hub card(not controller) as update, since then boot up stops just after wallpaper (not always about 1 in 5 times so far)and goes to boot menu where clean boot can be acheived in normal mode. Also, when opening system info and click on Multimedia tab my screen goes blank and A drive continues grinding until blank disc put in and it then reboots!! Helproom suggest it maybe graphic card and reinstall gfx drivers - how - don't have gfx drivers only gfx is sierra.pa4 files? Have athlon 800,legend TNT2 M64 32M graphic card running win98se please help someone as only basic user so step by step instructions please. Thanks.
