do u thing clearing the cmos might help----is that done differently from mobo to mobo because i know how to do it on my mobo
but my brothers comp that i am having this problem with is a dell and i dont have any info on the board so would i still just look for a cmos jumper and do it like with my board or would it be different??
Try looking for a clear CMOS jumper on the mobo (usually one nearest the battery). However most Dells do not have one. So your options are either:
1. In bios, reset all settings back to default, if this option is available.
2. If not, remove the cmos battery from the mobo. Be careful getting it out so you don't damage the holder. Leave it out for about 10 mins, then replace it.
Not sure if clearing the CMOS will also clear NVRAM so may not be sufficent. If bios has a 'clear NVRAM setting', try that.
If not, tell me that exact model of the Dell (eg Dimension 8200 etc) and I can tell you the prodeure for clearing the NVRAM.
