I don't think for a moment the memory you have is causing this. You would have been seeing other problems like startup hangs along with possible multiple audio beeps at post. Board related, cpu wearout most likely. A weak battery can't be ruled out. But that usually stalls a system not repeat restarts over a period of regular usage.
This has been going on for too long suggesting bad caps on the board since the supply can be ruled out. Or possible chipset or bios eprom failure coming on. That would be the hardware side besides the video card. Some updates even for Socket A boards had a winflash program. Otherwise burning the Asus awdflash tool onto a cd would be the option.
Looks like its at 1.65 anyway, and as far as what PCeye said (no) increasing your voltage from 1.60 to 1.65 when those are the recomended voltages will not hurt anything! But your 12v voltage looks a little low at 11.73V. Down load PC Wizard and see what it says http://www.cpuid.com/pcwizard.php
It could be something as simple as a driver or a installed program, I would update (all) the drivers-chipset-sound-lan-video card and not from ASrock. think that one has a nvidia chip with Realtek lan and CMedia AC97 sound
It does tell me there's a driver problem when I do the error report...
But when I turned off the automatic restart thing in advanced options, I got the blue screen, but nothing on it, it was blanc.
I tried getting the latest sound drivers once and had to get the old ones because the sound went funny when I was playing Oblivion so I went back.
Yeah, it has an Nvidia chip but I'm using a graphics card on the motherboard.
Alot of the time the board manufacture will be behind on the drivers on there site. Have you tried these for your sound http://www.cmedia.com.tw/?q=en/driver
I,m not a big fan of ASrock but I have had a few that ran right When I used to Build Socket 462s I hated Abit boards, the boards were good but had alot of bios issues, yea your kinda stuck on upgrading there, going 939 would be just another dead end and going AM2 or C2D you would almost have to replace everything
Oh right, this is an ASRock one too, The 775DUAL-VISTA, It looks good!
I'll get back to you later on weather the drivers work, I'll also update the BIOS and see how that goes.
Notice there is two ATI X850 drivers, which one should I get rid of?
Also, I noticed it happened after I installed the drivers that came with my monitor... I don't think I really need then as it goes through my graphics card and it may be interfeiring... Could be a display driver clash or something?
