Hi there, I changed my hardware a few weeks ago : athlon xp 2600+ ati 9600 pro At the beginning my computer would always freeze just after windows (xp) started. I therefore tried to change the FSB in the bios, but I'm not really used to it ; anyway I don't know what I've done, but since I've made these changes to my computer, it won't boot up at all. It's now totally impossible to get into the bios and my screen just displays 'no signal'. The harddisk led keeps flashing in red, and the fan seems to be running properly ! I've already tried to remove the motherboard battery, and I've done a CLEAR CMOS, but this hasn't changed anything ! What do you suggest I do ? PS : I'm really sorry, you may receive this kind of question hundred times a day but I really don't know what to do !
