HI, I really need help before I have to resort to putting PC into repair shop. I have two OS the same on two parts of hard drive which is called c but when I reformat with start up disk it check C and D, my cdrom is called f my cdrw(which will not work) is E..........but only sometimes .sometimes cdrom is E. I have to defrag every day or there is no space left on hard drive.Direct x will not work as there is not enough colours,only 16 or 2. All this was achieved unknown to me by helpful friends. I want it back to how it was with one OS no partitions ,one hard drive . how do I undo all this. If I try to remove windows on the part of drive called D it says I cannot remove a networked drive. The ethernet contoller does not have a driver,pci does not have a driver the problems are endless.please help
