... I have serious issues.
I have GTX570 SLI. When SLI is on and the pc is oc'ed my computer wont post. It skips posting giving black screen for 20-30 seconds then opens log on screen. No access to bios. When I pull off power cables the pc posts normally. So if I have to go to bios I have to always disable another gfxcard. Another issue... sometimes, when SLI is on + the pc oc'ed, Avast wont start up. And also net connection is disabled. Atm Avast doesnt work but net connection does.
Here are specs:
i7 firstname.lastname@example.org GHz/1.34 V w/Noctua NH-D14 (max load temp 55, 58, 61, 56 C)
Asus Rampage II Extreme/Bios version 1904
GTX570 SLI (max load temp 58/49 C)
Forceseries F240 SSD
Kingston HyperX 6 Gb/1600 MHz/1.65 V Default timings
HT and other similar settings are off
Other voltages are set to AUTO
Is there any known problems in generally on AUTO voltage settings? When I set default bios settings posting is normal even if SLI is on. So do u have any idea what oc'ing or I do wrong?
Thanks in advance.
People that buy OEM systems think Linux was a Charlie Brown character, a registry is something you see at target to buy shower gifts, RAM is a Dodge truck and a hard drive is DC at rush hour.

According to a Bit Tech report on the Power consumptions
We see that the GTX 570 at the wall will pull 330 watts of Electricity.
Lets be conservative and add to that another 220 Watts of power for the second in sli.
That is 550 pure watts. That is no CCFL lights and no frills. Just the system board cpu and few other things.
IF Avast is not starting up.. I would uninstall Avast and then Reinstall it for a second time. Remember.. MicroSoft has been doing some massive new security updates to the OS lately so it just may need a Reinstall.
Other than that I would use Microsoft Security Essentials. It is good and free and will work with all your stuff.
About the PSU. Well we don't know what kind it is. if you went cheap on the PSU then You are spikeing it but that would have no issues with just one piece of Software.
