pc switching off

**Mr_Miyagi** · April 19th, 2007, 02:50 AM

my wife's pc is now switching off and refusing to restart unless you turn the power off entirely or unplug.

initially i thought it might be overheating or have a faulty powersupply; i have changed the psu from the old 450 to a new 500w and it made no difference.

the agp graphics card has a 40mm fan that appeared to have a problem spinning up and i was looking to replace it, but it has a micro-2pin plug that no one in the UK can supply me! there's no extra 2 or 3pin sockets on the motherboard.

the cpu and case fans appear normal.

here's the strange thing, i am typing this message and so far the thing hasn't crashed... the difference is the side of the case is off. (this factor was why i originally thought of overheat psu).

any ideas?

Clean out the dust in the hsf?
Changed the video card?

I dont see anything about changeing the HSF so replace the heatsink and fan

what a clutz.. cleaned off the hsf and it seems to be ok; cant believe the dust in the hsf; and cant believe i didn't do it first! it was only 3 yrs ago i was an engineer!

anyway, still looking for a 40mm fan with a micro plug 2-pin...

Dust destroys the sleeve which keeps the fan quiet. Very shortly it will become noisy

Well get a fan and splice the cables together with the plug

well, noonoo, there's a novel and unique idea!

i cannot believe, what with all the mobos out there, (including video cards), that have micro 2 pin plugs, you just cannot buy them without having to resort to a bodge job...
