This system has run great and stable for about 8 months with the Phenom II 810 overclocked at 3.5Ghz. Then last month I bought a new Kingwin 100 watt PSU from Newegg (a shell shocker deal) because I was thinking of upgrading. I installed the new PSU and the system was fine for a while. After the install I had lost my overclocking settings and never bothered to overclock again until last week when I decided that I would use the Asus Turbo V Evo utility to level up my Phenom II 810 to the Phenom II 945. I thought that the Turbo V program would just try to achieve the Phenom II 945's clock speed and I should of done a little more research on the utility. In any case I accepted the level up profile and then rebooted my computer. As soon as the BIOS posted it issued a CPU voltage level error and shut down the computer. Now the BIOS will not post.

I reset CMOS which got me nowhere. I then removed my video card and one stick of memory to no avail. I tried different RAM, another PSU and still no post. I tried the mobo out of box and I tried my CPU and RAM on an MSI mobo and got the same outcome. All of my case fans start up and run and the hard drive is active as well. One thing that I have never encountered and seems odd is that the fan on my Scythe SMG 2100 CPU cooler seems to run at kind of sporadic speeds. It revs up and then almost slows to a stop and keeps doing this. I am at a loss right now for ideas so if anyone could help me out I would appreciate it a lot. The big question that I have is; Is my CPU done for?


Thanks for any help.

If you tried this on a second motherboard and got the same error, then it seems clear the CPU is toast.

Note that Kingwin is not known for making quality supplies. I look for power supply brands listed under the "Good" column of PC Mech's PSU Reference List.

Also, you said, 100W. What did you mean?

 

Sorry I meant 1000 watt. Thanks. I was pretty sure that it was the CPU but I just wanted to make sure that there was nothing I had missed. From what I have learned from other threads, overvoltage can be extremely dangerous to the whole system. So maybe I got lucky on this one. I sure learned my lesson about about auto overclocking. Thing that really bugs me is that I am almost positive that I had vcore locked in BIOS. Oh well.

Yes I know about Kingwin but they had really been getting a lot of good reviews lately and Johnny Guru had reviewed three of the OEM SuperFlower PSU's and a couple of Kingwin PSU and it seems that they are moving up in the market. Still I know that it is not of the same quality as a Corsair or Enermax but this is one extremely stable PSU even if it is not as efficient as some others. I feel like its a big step up from my old hec XPower Pro that I was using.

Thanks for your help
