I took the pc home and opened it up to have a look it was incredibly dusty. I took out the memory ram and placed it into a different slow. After this the pc booted up but there was 1 long beep followed by 3 shorts beeps on start up. The bios screen said there was a cmos error and it had to be reset i rest the cmos and bios to optimum settings and the pc worked fine. Everytime i tested the boot up i got the same 1 long beep and 3 short beeps followed by 2 quick beeps a little later on. The pc booted up 7 times on the trot and even when i tried it later in the day it booted up.
The next day i tested it and it didn't boot up. I moved the memory ram into the third slot and the pc booted up again with the 1 long beep and the 3 shorts beeps.
I wondered if the ram slots were going on the motherboard as i have tested a new memory chip in the pc and it did exactly the same thing.
Looking up the beep codes they state that it could either be a memory problem (not seated properly or bad memory) or a graphics card problem. I unfortunately cannot put a new graphics card in as i don't have access to one at present. I live in the sticks in spain and because of this it is not too easy to get hold of parts.
I was just wondering if this sounds like a motherboard or graphics card problem. I realise that it is hard to say without seeing the pc but if anyone could point me in the right direction in terms of tests i could do or any thoughts it would be very much appreciated.
I don't want to tell them to fork out for a new graphics card or motherboard and find out that still doesn't solve the problem.
Thanks in advance for any help you could provide
