I'm having tons of problems with ram upgrading and i just cant figure out what's the cause. Here's my story:
At first i had 2 Patriot 1gb 800mhz ram sticks. After a while, i bought an OCZ 2gb 800mhz, which caused my computer to freeze regulary.Memtest 86+ didn't find any errors. Later on i found out that the CAS latencies of my old ones and this new one didn't match, so after trying a few more things, i returned the OCZ ones and bought 2 EXACTLY the same sticks as i allready had. After this i had even more problems:
either the computer started without a beep and there would be no display or it started normally and i'd get BSOD often. So i did a memtest for everyone of the sticks (one at a time) and there were no errors yet again. Another weird thing is when i did the tests with the new ram sticks (like i said, one at a time), the computer started normally, but after that when i tried to run it with both of them (but without the old ones) the no display thing happened again.
I really have no idea what to do, so any advice would be much appriciated.
