About 30min ago, my other half's pc froze and there was that smell. no noise or visable smoke.
We quickly powered down and I open it up to have a look, nothing I can see is bad.
Just tried to power it up again but get no monitor output.
Wondered if it was the psu, so I opened that up, it's a thermaltake tr2, not the best of psu's and I did replace te fan a while ago with a 1600rpm scythe s-flex.
I wasn't too worried at the time with the fan swap as I know the s-flex moves more air more quietly the the rather bad stock fan (I tested them before I swapd them over)
I cannot see or smell anything wrong in the psu, although I managed to snap th fan wire at the connector trying to deconnect it so I'll have to solder that back on, before I can test it.
The pc is a p4 HT 3.0ghz socket 478, msi motherboard, agp graphics (my old fx5200)
Again I cannot see any burn marks or blown/bluging caps and the smell has now totally gone.
As I'm still half way through swapping my own pc, so I just quicky pulled the hard drives out of my p35 and stuck in her main hd.
windows tries to boot but restarts, f8 to cancle automatic restart on error and the blue screen reports disk errors, so I've used the xp cd to get recovery console and and now running a chkdsk to see if it can fix it.
Although it might be connected to the odd hard drive layout she has, there's 2 old ide hd's that are partitioned up (it's a lng story, she just refused to be parted from them as they've got software installed that the original cd's have been lost and she cannot do without)
Big pain is I don't have a spare agp card to test with any more and due to my nice cable management it's going to be a right pain to get the psu out of my pc to test.
I'm thinking it's probably ether the motherboard, the psu or the graphics card.
Although for a while now I've been meaning to finish my new pc and use the guts of my old one to upgrade hers, the whole process has been held up as she hates megoing anyware near her pc when it's working and I been procrastinating over my upgrade.
So at least this has pushed things to a head and I'll have to actually do the work now.
(also planning sme case mods at the same time )
