problems booting

[rahan46]

Been having problems with my computer booting. Before I went away I unplugged the power cord and just left it (so it's been sitting for 7days not turned on). Anyway I get back plug it in try to boot and all the fans/leds/cd-roms spin up but I get no video and no POST beep. The cd-rom will even open/close fine but on the keyboard the num lock key will not light up like it usually does. Anyone have any ideas? (The mobo is grounded fine so i dont think thats the problem)

first ting i would try is resetting your cmos to factory default by either a jumper or if you cant find it removing the battery

Monitor is plugged in fine and also tried resetting the CMOS.

Sounds alot like an old machine I have.

First, what kind of Power Supply do you have?

Second, do any of the capacitors (large can-like objects, usually blue) on the motherboard have brown stuff on them or appear to be 'bulging'?

The powersupply I have is a allied 400w.

Okay, doesn't sound like the PS then, unless it's malfunctioning.

Now check your caps.

Do you have a video card or do you have onboard video? If its a video card I would reseat the video card..that would be my first step.

Did you unplug any USB devices and plug them into a different port when the computer was off?

Did not plug/un-PLUG any USB devices when it was off. Now when I tried starting it, it made a whining noise yet the CPU fan is spinning fine. It doesn't sound good..
