I have a Dell Dimesion 4550 and have intermittent problems with the start up. I get the Dell logo flash up then the pc beeps and a message saying 'the system memory has changed' pops up with other stuff on a black screen. The options are F1 to continue ot F2 to access start up page. When I press F1 this usually resolves the problem and it loads Windows ok. However last week I was not even getting to the error messsage. The pc just wouldn't start. It finally started after about 20 attempts and we are back to the same issue. I spoke to Dell and they said the hardware memory is corrupt and they no longer do a replacement for this model so I need to buy a new pc. Is this right or can I solve this problem.
Please note I'm not very technical on pc's!!
