My computer has been running fine up until last week when it took hours and several attempts to get it started. Then at the weekend it wouldnt start at all, there is a power light on the motherboard,the fans and the dvd power up and the hard drive starts and then clicks a few times and thats it. The orange activity light is permanently lit, i first thought it could be the hard drive but now i have replaced it and still the same. Its over 4 years old, a Mesh pc with an athlon chip and asus m2npv-vm motherboard. I'm going to see if i can cadge a psu to try but any other ideas on the cause?
Thanks for the replies, i'm on the on board graphics now as my graphics card died a few months back. There are no beeps when i start up. I managed to borrow a psu today and managed to get the power light lit, which it wasnt doing before, and got to the first boot screen where it gives details of cpu and memory, but then i get a load of text and i cant go any further. It says press del to enter set up and f8 for boot menu, but pressing any of those does nothing. There was one connector missing from the borrowed psu which fits under the main connector on the board, so maybe i should buy a new psu and hope for the best
Just managed to find the motherboard manual online, i have the 24 pin EATXPWR plug connected, the one i'm missing is the 4 pin ATX12V plug, and it says that if this isnt connected the system wont boot up, so i guess i'm going to have to try a new PSU
