VCore voltage problem_+3.3V red.

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

you need to go to cmos to do that

Really?

Are we talking about the Asus P5LD2-VM motherboard, Zoltan?
(Zoltan is a C-o-o-o-o-l name!)

Because I'm looking at the motherboard manual right now, and state you are mistaken.

1) Use the Right Side Arrow key, and highlight the - Advanced - tab on top of the Main menu.

2) Use the Down Arrow key and highlight -
JumperFree Configuration
Press the Enter key.

Configure System Frequency/Voltage
AI Overclocking - [Auto]

Use the - key, (Minus), and move Auto to Manual
Use the appropriate arrow key, and highlight -
CPU VCore Voltage [ Auto ]
Press the Enter key.

There are 40 Voltages you can choose from.
1.7000Volts to 1.2875Volts.

Remember,
Use SMALL increments at a time. Do a 24 hour stability test.
(Small increment example, 1.7000V to 1.6875V )

If your system is stable for 24 hours, then you can come back, and change the Voltage one more small increment.
(1.6875V to 1.6750V)

Also remember; you are changing the Front Side Bus of the Processor. (FSB)
Change it TOO much, and your ram memory, and expansion slots will not work.

(Ram Memory typically operates at a frequency rate ('Speed'), of half of the FSB of the Processor.
Processor FSB is 800MHz for example? Ram Memory operates at 400MegaHertz.

Intel Core2 Duo E6300? 1066MegaHertz Front Side Bus.
{1066MHz FSB}
Ram memory? 533MHz)

Vcore settings can usually be found in the bios settings menu. But be careful when playing around with those settings!

Hi glen909nwi,


Here's the configuration for that board. If your trying to overclock, you'll want to go with a higher setting.

Just got to into your Bios and reset the factory settings and It will reset the changes you may have made.

hi- i would say that it is a heat issue. check the temps of the cpu-also check some of the bios settings, my asrock board has some bios settings that are for safe overclocking-like bumping up voltage. set these to default.-one is called vccm, then vlink,then over vcore. vccm set-to high- vlink set to normal- over vcore -disable. but do check the cpu and if you have some heat sink compound- take the heatsink off and reinstall it with the new compound. make sure you clean the old compound off. if you need more help-reply good luck!

First I would make sure all the power plugs are properly plugged into the motherboard and all other devices.

If that does not solve it then I would get the Power supply tested at a local PC shop. Or just get a new decent power supply. Looks like the Power supply without a doubt is defective.

If you have an adjustment for the VCORE voltage in your bios, bring it up by one value, then try overclocking the CPU.
