freezes & crashes

hey there,

first of all, sorry if this is in the wrong place. i've been reading these forums for a while and this seemed the right place. I also noticed the high level of expertise around here.

secondly, i've got a really annoying problem. always on first startup of the day my computer freezes up, requiring a hard reboot which is usually followed by "no signal" message on my screen.

i've done a memtest. when both RAM sticks are in the computer i got 800k errors in like 2 minutes but when done seperately i've got no errors so far till pass 3.

since there is no bluescreen there is no minidump (right?) atleast, i can't seem to find it

i really hope this problem will be solved

thanks in advance,
Dutchdarky

my computer specs are:
motherboard: asus m4a79xtd EVO
CPU: AMD phenom x4 955 BE
videocard: ATI radeon 5770
RAM: kingston 4GB 10600
power supply: cooler master GX550W

i got the computer in September 2010, the freezes started around December 2010

This means the RAM sticks are defective, you should buy new ones :)

well i dont think they are, since i tested them seperately and got no errors, but when they are together they do give errors (-> motherboard?)

i still got warranty on everything in my computer so i wont buy new but i'd send them back ;P

bumpy, could this be a motherboard issue instead of a RAM issue. since they work fine seperately according to memtest86

sadly it didnt work i left 1 RAM stick in overnight and just booted, i still have the problem. switched the sticks and the very same happens

small update:
RMA'd the whole system as they put it together and they wanted to test it in original setup. they claimed to have found nothing so they sent the system back without any changes. however, the freezes are gone

thanks for all your help guys :)
