Re: System won't budge
Sounds like a power on/power good signal fault. Could be the power supply or the mobo. The voltages can be read at the ATX connector: http://www.formfactors.org/developer\specs\ATX12V_1_3dg.pdf or you can try another if you have a spare power supply to verify whether it is a mobo problem or power supply. Also there are power supply testers but they cost almost as much as an inexpensive power supply. It's an easy replacement task. Steve Medley

During the boot process you will see on the screen to press a certain key to enter setup Press and hold that key during the boot up process to enter BIOS you can load failsafe defaultsor load optimized defaults ,press escape then press f10 to save to cmos to restart or During the boot process tap thef8 button three times this will boot into safe mode where the only things working will be your mouse and keyboard enabling you to attempt to repair your computer Also you might try Turn Off the computer, now as soon as you hit the power button, keep on holding "Alt" key & keep on tapping "F10 key,ie: Alt+F10, it will open the recovery console ,select full factory restore and follow on screen instruction. (Note:this will erase all datas on the computer)
Disconnect everything from the motherboard except the power supply, CPU and power switch.
Turn on the computer. You should hear 3 beeps because you removed the memory.
If you don't hear any beeps, check the power supply. Check all the connections. Did you connect the 4 pin power? Did you skimp on it? A common mistake is to get a cheap, high-power supply. Just because the box says it's 1000 WATTs doesn't mean that will carry a steady load.
It's either a bad motherboard or processor. If you have another processor that is supported on that board and you know it works, try it. If it boots return your CPU for a good one.
Unfortunatly, if it doesn't boot with a known-good processor that just proves the board is bad; it doesn't prove your CPU is good. You may have more issues.
You may have a high end video card installed, which will need a big power supply.
Try removing all parts except the CPU and video card, your system should still boot to the bios post screen, If still no go try a new video card, cpu. you will need to keep swapping parts around tell you find out witch one is causing you the prob, its the only way to sort out a hard ware issue. Hope this helps Have a nice day.
1. Processor is cold dead.
2. Power Supply has got a problem. Just powering a fan is not a guarantee that it is powering everything normaly. Try a different one as you test agai.
3. I suspect your MoBo is good, but try a different video card also with your new DDR.
4. Do you hear the HDD cranking or whining when you turn on the PC? Keep ear near HDD and listen. It it whine-starts, it's a fair sign.
5. Try a different monitor while you test these.
Do you hear any beeps at all? Do you have a system speaker on the motherboard? If not, plug a 2-pin system speakers onto the motherboard where it says "speaker" and listen for some beeps.
You may have a fried CPU or dodgy RAM on your hands. Possibly even a faulty AGP/PCI-E slot, to name a few.
