I built my PC just over a year ago, noob first time builder .It has been running fine till about a month ago.
I installed Half Life 2,started it up and 5 minutes later an alarm went off and the PC shut down. It has been giving me problems ever since.
These are the problems:
1) Sometimes after startup it will just shut down after loading windows. After a restart it won’t do it again that day.
2) Vcore is usually 1.42-1.44 v, several times a day the alarm will go off and Vcore will show 1.57 v for about 4 seconds then return to normal. This happens during game play, surfing or idle.
3) It seems to be running hotter than it used to, CPU/MB 37 C while surfing/idle, 40+ C during gaming. Heatsinks are all clean and fans seem to be working. It worked fine through the summer .I’m in SW England so its cool now. The alarm goes off if CPU/MB gets above 42 C.

I have ASUS PC Probe 2 installed to monitor temps/voltages, this is what it usually shows:

Vcore = 144 – 146 v
+3.3 = 3.18 - 3.25 v
+5 = 4.78 - 4.92 v
+12 = 11.71 - 11.90 v
CPU Fan = 1180 rpm

Is this likely to be a MB problem, PSU or what?

System:

Antec NEO HE 430 PSU
ASUS A8N32 - SLI Deluxe
Opteron 146 @2.0Ghz
Thermalright Sl-120 Heatsink with Nexus 120mm case fan
2 x 1 GB Corsair 3500LLPRO
ASUS Extreme TOP 7800GTX

Appreciate any help or advice, thank you
 
I'd say it's your PSU. I think 430 watts might be kind of weak for a 7800GTX. I could be wrong. But your right on track between psu and mobo. I would maybe try another known better psu, maybe from a friend? See if that helps. If it does, get a new one. If it doesn't then it's your mobo.

Or if you could, check your 12volt molex connection with a multimeter as the pc is booting into windows. And if you get that far, then check it as it's running a game that will put a load on your system.
 
I don't think its a PSU problem, Because that motherboard has over voltage options. Do you have them turned on? It automaticaly increases voltage to the cpu if the option is turned on, if you do have it on, turn it off in a bios and manually set your desired voltage.
 
i have the BIOS setup pretty much to default values.I looked for somewhere to set voltages and couldn't find anything.TBH I wouldn't know what to set it too anyway :D

I did discover another problem though.Sometimes the PC takes a minute or more to load windows.When it does that and I check Event Viewer I notice several disk errors:-

Event ID:51

An error was detected on device \Device\Harddisk0\D during a paging operation

Could this be another sign pointing to the MB as the problem?
 
Not really thats fairly self explanatory in that it states its an issue with the hard drive but that isn't going to set off any alarms. Is there any way in your bios to increase the alarm threshold to a higher temperature? The power supply could be at issue but if its in good order and the system was running properly with it before then theres no reason that it shouldn't run it properly now. The power supply is an Antec and they don't build shoddy stuff and usually if somethings is going to go wrong it goes wrong early on not after a year of use. If the motherboard has a "SMART" option in the bios it would be a good idea to enable it if it isn't already just incase your HD is headed for the crapper. At least that way if the HD is on its last legs you can back up any important data before it heads south. I can't think of a mobo that would alarm because of a HD issue.
