quick info - its my sisters computer, so i only know what she has told me
its a packard bell b2218 uk, using vista basic, using on-board graphics.
the problem started yesterday when the cpu fan started making a noise and freezing so she shut it down and took off the case and found that the fan was full of dust, she carefully cleaned it out and started it back up and it worked good for about 20 mins, then it froze and she held the power button down to turn it off and turned it back on and now the fans and power light come on, hd seems to spin but nothing else happens, no video signal, not even a beep.
I have tried a graphics card in it (as its been using on-board) disconnecting the DVD drive, hard drive and ram and when its down to just the CPU, there is 1 very long beep but that the only beep i can get out of it. I have also used different ram in it but that also does not work.
can anyone recommend anything to try or something like that, to find out where the problem is ?
thanks in advance for any reply's
