hi i am having problem with my pc. i built it few months back and i have had freezing issues. my computer would randomly freeze while windows updating, downloading, surfing the internet, etc.

i talked with my RAM manufacturer and they said that the ram might not be fully compatible with my MOBO. they told me to increase the voltage for my ram. i did from 1.9v to 2.0v and it actually worked, but i still freeze a couple of times a week. i tried TALKING to the mobo manufacturer and they told me to update bios or try new ram. i bought new ram for it, but im still having problems, but i actually havent updated bios yet.

my question is: is my freezing related to bios being outdated? would updating it solve my freezing problem?

here are my other issues:
i cant use more than 2gb of ram. when i use 3 i get program crashes and when i use 4gb, i blue screen (bsod). i ALSO noticed that putting one stick of ram on the 3rd memory slot gives me bsod.

could there be something wrong with this mobo? if there is, can i just change my mobo and use the same other parts, would i have to reinstall windows?

thanks

vista home PREMIUM 641st of all,are you sure it freeze wasn't because of overheat?how long will it be fine until it's freeze?When you attach your processor to the mainboard,did you apply any thermal grease?see here
http://en.wikipedia.org/wiki/Thermal_greaseim pretty sure my temps are fine. i use speed fan and it says my cpu runs around 30-45

and actually i can play GAMES at max settings for hours and its no problem.

my computer freezes sometimes when:
i leave it on overnight
leave it on with downloads overnight
updating windows
just randomly too sometimes

also it freezes when it gets to the loading screen of vista or right when i get on desktop. so i sometimes would have to reset my system 2-6 times before i can get on desktop and do thingsOnboard NIC or an add on card for your network connection ? ?what about them?

i have updated them to latest version from nvidia.

now i actually did a windows update and it seriously screwed up my system. now it makes my computer freeze bigtime. any ideas?have you check device manager?
take out all of the part,just leave the basic (keyboard,mouse),see if its happen,
use the ram that you sure fine
take out the nic & add on card,disconnect internet.
give it a try.....Does this happen in safe mode ? I just re-read your original post...which RAM manuf. told you to fool around with the RAM voltages ? ?actually i talked with gskill. they told me that their ram had issues with nforce 650i boards. so they told me to increase my voltage which actually made the system more stable.

i tried corsair ram and it was the same thing, kept giving me freezes.

and now, i think i may have good news. i bought a new motherboard and swapped it to my old one. i bought a gigabyte ga-p35-ds3r/s3r board, and right now everything seems great. i even have 4gb of ram now that i couldnt use with my ecs 650i board.

i guess my old motherboard was broken from the very beginning.

thanks for your help guysGood to hear you are fixed up...don't give gskill any more of your business.actually g skill is pretty good, im using 4gb of their ram right now.

its the ecs mobo that was defective, and their support was useless. so i will be staying away from them.
