3 beeps when start up but nothing on screen

[nsimpson72]

I built a pc for a friend using some of my old parts from my old pc (which was working). It booted fine and I installed some anti virus software. I installed more ram but was the wrong type so removed it. Now I get 3 beeps when I turn on power and nothing comes up on the screen (not even bios). Ive tried resetting the jumpers, removing each original ram card and the graphics card but still 3 beeps and nothing.

Yep had a look at those codes as well, does the fact i put in the wrong type of ram cause the other 2 ram cards (that were working before) to fail? as it wont boot up with the original 2 cards (that were working before)?

what is the beep code telling you?

how was the RAM "wrong" ?

 

[nsimpson72]

it was ddr2 it should have been sdram. the beep is 3 beeps but in the lists ive seen all the codes have 1-1-2 or 1-2-1 but no 1-1-1 which i think the beeps are telling me. the 2 things ive seen on forums are either the ram cards are now faulty or its 'first 64k memory fail' !!

I would say you have damaged all the RAM .

Static electricity on your hands can damage it very easily . Its a part that you have to handle very carefully .
Never touch the chips , never touch the contacts

ESD controls were in place (worked in microelectronics for years). But the mistake of the wrong ram would suggest Ive f***ed the existing ram. I have ordered the right ram and should be with me in 2 days. Hopefully the beeps will have gone once I fit the new ram.

Ok, new ram arrived and fitted.....still 3 beeps and nothing comes up on screen!!!!!

Try taking out the CMOS battery and leave it for like half an hour. I had a similar problem and that fixed it for me.

Ive already tried that thanks, also moving the jumper to reset the bios.
