Help please overheating problem

hi all really hoping someone can help me out here, this is my last resort before i chuck the pc through window,

this is my third attemp at making this thread as i get so far then the pc shuts off instantly,

my pc is about 4 year old, heres the specs

amd athlon 64 5000+

abit kn9 ultra

nvidea 8800 GTS 320 mg

5 Gb DDR 2 Ram Corsair
750 Gb HDD

the pc started shutting off a few months ago, since then its got worse , it only did it when i started a game or played music,

so i decided o download some temperature software to keep an eye on the temps, and i thought it was off that it was idling at 50 degrees

and when i open a program it shoots up tp over 100 degrees then shuts off

i have changed my pc case for a new 1 with more fans, and it still crashed

i decided to put new thermal paste and reseat the heatsink ( hoovering out all the dust first) and still it crashes

so i thought it might need a format as i was still using xp that had been installed on the pc since i got it,

so today i put windows 7 on , hoping and praying it wouldent crash, anywayz i managed to get it installed but soon as it started updating with windows Booom it went off again

no blue screen of death, no errror when rebooted , nothing , it just boots up like nothing happend,

anyways here a screen shot of my temps when windows 7 is updating ( i cant actually finsh the update process without it turning off, if someone can suggest anything i havent allready tried
then please do

also my pc is in my living room we only use central heating and never gets above 24 degrees in the room

  1. What CPU cooler do you have?

    I know you re-seated it, but is it a Passive or Active heatsink?

    If it is Active, check the fan. Make sure it is working
  2. im not 100% what the difference is lol , but the fan is working, and spinning at about 3500 rpm
