I have a friend who has a system based on the above mother board. He has a AMD2000XP processor in his system and 512Mb of ram. He seesm to be having a lot of problems with switching his PC on. When the PC is switched off it is rare if it can be switched on from the on/off switch. More often than not he has to use a switch just under the power supply unit on the back of the PC in order for it to come on. When he uses this switch it take him a few attempts before the PC comes on, but the strange thing is that when this switch does work the PC will switch on without the need for the on/off switch to be pressed. Has anybody else ever had or heard of a similar problem and if so does anyone what the problem could be.
