Hello, and thanks for taking the time. System Setup: Intel Q6600 Quad 2.5ghz MSI P45 Platinum Mobo Bigwater 760is (stupid I know) Liquid Cooling System Nvidia GTX 260 Corsair 750Watt PSU 8GB (4x2GB) Corsair DDR2 Ram Acer 22" H213H monitor connected via HDMI All the drivers are up to date. The computer sometimes feels like sending signal to the monitor, sometimes it doesnt, This problem usually arises whenever I reboot the computer and will go away after a while. But this time it just wont send the signal and it's been quite a while. Things i've already tried: CMOS Reset GPU PCI Slot Switch Switching Monitors Switching output signals (tried all 3 HDMI, DVI and VGA) Moving around RAM sticks from one slot to another Added the Power converters that came with the GTX260 instead of direct PCI express cables since the manual said those were better.

I don't know why people waste money on water cooling...the fact that you wrote "stupid I know" tells me that you realize it wasn't such a wise investment. Are you getting any beeps at startup? If not, the problem is with the CPU or motherboard.
