Hi guys, im having a problem with a new PC ive built and i can't figure out for the life of me why it wont work. I start it up and everything starts up but it doesn't post. Nothing is defective as it has all been tested (except the video card). Im not getting any beep codes but the MemOK feature with the DRAM_LED is fixed on which in the manual says the RAM isnt compatible. However, this RAM is 100% compatible as i know someone using it with this same motherboard and processor. Ive been through the tomshardware check list of things that could be wrong but nothing seems to work. Anyone got any ideas on what i can do?
Motherboard: Asus P7P55D Pro.
Processor: Intel i5-750.
RAM: Corsair XMS3 4GB 1600MHz (CMX4GX3M2A1600C8) (Originally had the Corsair Dominator (CMD4GX3M2B1600C) but this didnt work.
Gfx: XFX Radeon 5850.
PSU: Corsair HX750W.
HDD: Samsung F3 1TB 7200rpm.
CPU Fan: Zalman CNPS9900 LED.
Case: Coolermaster CM-690 Advanced 2.
There is no software installed as i have NEVER managed to get anything up on the screen. Your help will be much appreciated thank you.
