I'm beginning to think I must be jinxed. Having two apparently dead mobos, I decided to actually buy a brand new one, and start the project of building a pc from scratch. Mobo is: ASRock K7S8X Processor: tiny Athlon XP1600+ (taken from working machine) RAM: 256Mb PC2100 The scenario: put it together, double checked all connections, booted it up, POSTed, went into BIOS ok. Recognised the relevant components, requests F1 to set to default........ and crashes when I hit F1. I clear BIOS at CMOS, try again. Same thing happens like Groundhog Day. Finally I just let it sit on BIOS screen, did nothing, and after a couple of mins, the screen went blank, screen light dimmed. I have to be doing something seriously wrong here. Does anyone have any ideas?
