Hi, I'm new in the forum and also new in building pc's. My system is like this:

MoBo: Asus M3A79-T DELUXE
BIOS: 0703
CPU : AMD Athlon X2 7750 Black Edition (with it's AMD heatsink and fan)
Mem : Corsair Dual Channel TWINX 4096MB PC6400 DDR2 800MHz Memory (2 x 2048MB)
Vid : XFX GeForce 9800 GT - 512MB GDDR3, PCI Express 2.0
HD : Hitachi Deskstar P7K500 500GB Hard Drive - 7200, 16MB, SATA-300
PSU : Ultra LSP750 750-Watt Power Supply - ATX, SATA-Ready, SLI-Ready, 135mm Fan
Case: Foxconn TLA776 (with two fans 92mm, 80mm)

I'm having some concerns because I've seen in the bios screen that my CPU temp is around 60*C and the Vcore is around 1.44V (I suppose Vcore stands for the cpu voltage... if so I've read that the nominal voltage for this cpu should be around 1.20V), besides that my MoBo temp is around 40*C (once it even went up to 49*C)...By the way, I don't know actually what's my video card temp but I can assume it's really hot. So at this point you must guess that my problem is HEAT!!!

Any ideas why is this happening, I have not OC anything... I have just installed the OS (Win XP Pro SP3) and de Asus drivers... How can I fix it?

Thanks for your help

1.44V is pretty damn high for a 65nm CPU. You should try putting the Vcore at "Auto". If that doesn't work, you should just manually input the Vcore for the processor, which it should hover around 1.3~1.35V.

dont set it to auto. most MB's will default on the side of more power that the cpu needs for "safety"

i'd start with 1.275 volts and go down as needed. ( should work if you havent overclocked)

difference between 1.35 and 1.275 is 7c on my e6750 at full load.

i cant comment on the amd heatsink/fan but if its anything like intels then it can get replaced for further temp reductions.

Though your temps are higher than normal it may not meant that your CPU is malfunctioning. First, make sure you load up on fans. Second, grab your ASUS driver disc and get the AI Suite and PC Probe II and install them... the AI Suite will allow you to crank up your CPU fan to 100% and all other fans connected to your motherboard and PC Probe II will let you monitor your temps. If you temps are still high you may have bad sensors on the CPU cores.
