Hi everyone
I bought 2 new 1gb RAM cards for my HP computer and when I tried them, no combination of them worked(I bought high density chips but my comp takes low density chips...oops) so i switched back to my old 128MB card...Now my computer wont turn on...when i plug it in a light at the back of the comp flashes green quickly..the on button does nothing...my theory is that I could have fried my old 128MB card...any opinions would be much appreciated...

ya you might have freid the card mabye the motherboard if it has 128mb of ram im guessing its old it probably cant support 2gb of ram

Thanks for the reply...I checked and my computer can hold 2GB of memory...The problem was tha I used high density RAM and my motherboard cant support this apparently...The last combination of RAM I tried was my old 128MB card in slot 1 and the new 1GB card in slot 2, the comp booted but only recognised the 128MB,that was the last time my computer turned on..would this combination have fried the old RAM or the motherboard?

the ram probably try a low density chip but ya never no it might be the motherboard you can always return the ram if its the motherboard

Thanks again for the replies.I guess the only way to find out is to try the right RAM and see what happens.

indeed this is why it is always best to nag on these forums for advice before making a commitment
also as far as i know in order for ram to function correctly/ at its optimum all your ram chips have to be the same speed and timings
