nightmare!

gave my box a clean this morning as it was full of dust, unplugged and tidied up most cables, took the cpu fan off and gave heatsink a clean (Sythe Ninja) while still on the mobo & chip and put it all back together.

Now everything spins up but it wont POST. Removed all cards apart from gfx and C drive, got it down to one stick of ram but still no POST.

Pretty sure its mobo or cpu related now. not sure if its worth buying new chip/mobo or get a new computer altogether as it's 2-3 yrs old now.

Any advice one what else to try?

spec-

Mobo Asus P5B
C2D E6400 2.23ghz
a 6700 Nvidia GFX(i think)
2*512 and 2*1gd Corsair value ram
3 hdds
antec sonata II case with 450w earth watts psu
 
yeah, i've checked all the connections, the 4 pin plug is connected.

the gfx is old and doesnt have a power connector!

also reset the cmos settings
 
Tried resetting the CMOS mate, do this by removing the motherboard battery for around 30 mins or so.

edit
/doh just seen you tried that
 
as you have removed all the other cards try reseating the gfx and fully remove the last ram stick and reseat it probably some thing has been moved slightly during the dusting
 
thanks guys, think it must have been the gfx card, left the battery out for a while, reseated the card and swapped to a different ram slot and it posted

checked as i inserted all the ram and still worked so put all the cards back in and it boots to windows now.

had a nice specced machine on the go too!
 
I rebuilt my pc today installed a new power supply, cleaned it etc and my RAID array went missing :eek:
 
That's what happened to me 2 days ago when i moved everything to my new case and won't get to Vista at all. Tried clear CMOS, etc and at the end i just pop in my Vista disc and did repair and then voila, works fine again.

Not sure what happened there tho???
 
im an electronic engineer and i come across stuff like this a lot at work, quite often by blowing air over dust and dirt on a pcb can sometimes end up with a tiny conductive particle gettin blow under the legs on the ics, resulting in a short circuit. one thing you can try would be to blow the mobo etc again with a more air pressure.

i may have missunderstood your title and u might not have even blown air over it but if you have its something to try :)

I had this exact problem! I thought it was several things, Graphics card - replaced still didn't work
HDD - replaced still didn't work
RAM - replaced, still didn't work
Tested the monitor on another PC - that worked fine

Found out it was the motherboard in the end, don't know what happend to it, just died :/
