Last night my Fiancee and I installed a new cooling system for the desktop. It's a Zalaman CNPS CPU cooler 7000B Cu.

Anywy we took the computer apart, took off the old heatsink and fan, and installed the new cooler, and then put the mmchine back together.

When we had everything hooked in and we boote up, the monitor didn't come on. The monitor is on, it's on standby waiting with te little yllow LED light, and when the machine boots up, it doesn't turn green or come on....

At first we though maybe something wasn't done right. So we checked everything again, made sure the HDs and the other components were all plugged in properly, and tried again.

Same thing, no monitor.

So then we thought maybe the video card whic is only a few months old went, which of course COULD explain the no video thing even though the machine turns on and powers up.

Tried another card, same thing.

I'm seriousy stuck, I hate messing with hardware, and we have checked everything, but the only thing we can think of is maybe the MOBO needs replaced. Anyone have any ideas?

Someone said to re-seat the RAM so I did that. I popped the case back off, Pulle out both RAM sticks, and put them back in, made sure they clicked, and tried again but it still shows a blank screen.

The monitor itself by the way is an Acer AL1916, and when you turn the monitor itself on, it shows the acer logo, which is odd to me, I dont have any monitors that ever showed a logo by itself, but it does none the less.
