	have you checked PSU, cpu/nbridge spinning but no post is a sign of fucked psu. smell it, does it smell fried

	Brilliant idea cybermonkey. I'll try the old hotswap with a bios chip. Don't know why I didn't think of that. I can get hold of a known working bios for that, use that to boot from then when booted put the old one in and try and flash it. If thats the problem of course.

ANY failed CPU will still allow a boot into POST, followed by beeps. Until control has been handed over from the logic chip to the CPU bridge, a computer will function. Something as sever as this points to power or failed CMOS/BIOS chip

	Im assuming you have reset the cmos?

	Everything else works. I've tried everything, this isn't the usual my computer won't turn on because it isn't plugged in. Was just incase anyone had had a similar experience and found a solution. Cheers anyway boys :thumbs:

	I didn't see what happened or I'd have a better idea. Wee cousins computer. What I was told it just woudln't turn on one morning.
PaulW	posted on 13th May 06 at 16:38
	you sure the cpu hasnt fried?? unless the PSU went pop-bang...
John	posted on 13th May 06 at 16:38
	Yip tried everything. I'll just need to see if they get back to me, if not buy a new board.
Steve	posted on 13th May 06 at 16:03
	and youve deffo changed the psu yeah?
John	posted on 13th May 06 at 15:57
	Tried all the usual stuff, good clean and no visible damage to any components. Need to wait on a reply email about it and see how long the warranty is. I'd rather not have to buy a new one.
Cybermonkey	posted on 13th May 06 at 11:02
	can be a real simple explanation, something metallic (dust?) shorting on the board. give it a good brush with a non-nylon brush
Steve	posted on 13th May 06 at 09:34
	if its dead, its dead usually, check the capacitors for bulging on the tops. Any that are bulging are blown and you can try and solder some replacements in if you like. Usually its not worth fucking around wit hdead motherboards though. take it youve tried resetting the bios? take the battery out for a minute and replace and try again. Seen this fix a few apparently dead dell motherboards

	I have an nf7-m here that won't turn on. Pc has worked fine for about a year and a half and on thursday it just woudln't turn on. I've tried every other component so can't be them. The red light is on showing the board has the 5v standby power. When the 4 pin auxiliary connector is in but the main power connector isn't and I fire up the power supply the northbridge fan goes. Any ideas, no visible signs of anything blowing up and I can only be annoyed trying so much with the multimeter.
