I cannot boot 64bit Hardy after Adding more Ram


I originally had 2GB's of ram on my 64bitUbuntu Hardy, I then bought some new matching ram and installed it , checked my Bios and it shows up in there, Ubuntu hardy it will load up to just before it shows the desk top then my computer will freeze. I have just ran the new ram ( 2 Gb's) and it will boot, I can use this Live cd no problems with my full Gb's ram
I must be missing something I am pretty new to Linux so take it easy on me

Try mem=2048MB and mem=6144MB boot options. Have you checked BIOS to find out how much RAM it is showing?

Append either to the line that ends in "quiet splash". Depending on your motherboard, you could also try 4096MB. Before you do any of this, you may want to run memtest (I see you have it installed) to verify whether it is not simply a bad stick of RAM.

Thank you for reply I will try that and then post back either way

Boot with the second (recovery mode) option - that way you'll get all (any) error messages rather than the useless splash screen. Let us know any error messages you get.

How about the recovery boot line? Does that work?
Was the extra RAM the only hardware change?

Not sure what you mean by recovery boot line.
I also change from a 17" to a 19" monitor it is strange because in recovery mode I used the fix xserver and now I can boot onto my desktop but my resolution is stuck on 640 x480 and if I turn on the ATI accelerated drivers and reboot it does exactly the same as before..freezes, so then if I remove 2gbs ( doesn't matter which mem moduals) and turn on my comp ,boot up everything is normal, in that it is running like it is supposed to, my comp can handle up to 8 gb's ram at 1066mhz

Some motherboards seem to have problems with 4 sticks of RAM. Check the site of the motherboard vendor. Maybe it is a know issue and there is a BIOS update available.

Maybe dual channel has been selected in the bios and it cannot
auto correct that.

Rather the sticks may be interfering with each other...EMI
