Hi, I've been running my Asus A8v-e Deluxe motherboard(with onboard wifi-g) in my system for quite some time now, never had any problem connecting to the net with the onboard Lan card. a week ago i decided to change my home network to wireless, and switched to using my onboard wireless card (ASUS 802.11b/g Wireless LAN Card is the only description i can get from it) it works and connects and all if i'm just surfing the net, but if i leave it on during the night downloading stuff it'll randomly restart. i tried disabling auto restart in system & recovery, then instead of random restart i'd get random blue screen of death that looks like this: http://alexleung.roundtablegames.ca/images/bsod.JPG so it seems this mrv8ka51.sys is a fault, but i've reinstalled the latest driver from asus, i have no idea what the problem is now... hope anyone can help

Using onboard Wireless LAN requires more system resources than an expansion card or USB dongle etc, if you are leaving it on overnight what else is running? How much RAM do you have and are you performing tasks such as downloading/uploading that requires constant connection?

step 1: reseating your RAM card step 2 : start comp without RAM no beeps[system failure] step 3: reseat the BIOS to default step 4: IRQ conflict [reseat wireless card] step 5 : MORE RAM required let us know the result

thanks for the replys, i'm a wireless newbie and i don't really know much about them ok i'll admit that i have do leave downloading going overnight, bittorrent downloads actually. so i guess yes it requires constant connection but that's about all i have running at night, Bitcomet with 1 download(usually) and Zonealarm Pro. I really don't believe Athlon64 3000+ and 1GB of ram can't handle a little wireless downloading... hm...i'm afraid i don't really understant your post girish_2500, are you saying i need to add more ram?

Set your laptop to restart every 2/3 hours Run a batch file with "shutdown -r -tt 2700" and also set bitcomet to start at windows startup. I had the same problem with bitcomet and maybe not coincidentally, Zonealarm. I set it to restart every 2 hours though and was fine. I noticed if I left it the disk cache went down to 0MB and thats why I decided to go with the restart solution. Maybe it could be Zonealarm? You could maybe try test with another firewall? Build a man a fire, he'll be warm for a day. Set a man on fire, he'll be warm for the rest of his life.

hm...setting it to restarting periodically doesn't sound too appealing a solution...i'd prefer a second opinion if there's any i could try disabling zonealarm but zonealarm is the only defence i have, if i disable it i basically would be naked on the web

I am having exactly the same issues, and I have check all the IRQ, memory and BIOS have no relation to the problem, as far as I know, it is to do with the driver talking to a wrong memory addresses, I have send email to asus, however there is no official reply yet.
