Hi all,
First post here in the forum and I'm afraid it's a problematic one :/
I did a new build yesterday with the following components:
CPU: Intel i5 760
MoBo: Gigabyte GA-H55M-UD2H
RAM: Ebuyer Extra Value 4GB (2 Dimms)
Graphics: Gigabyte NVIDIA GTX 460 OC
HDD: Hitachi Deskstar 1TB
PSU: Antec Basiq 500W
On first attempt at boot the fans started spinning (case, heatsink, graphics) and the power cut off after 2 seconds, after that power got cycled again (loop). The phase lights on the mobo at this stage were green, green, yellow, red. I've removed the graphics card and booted again and this time it did not cut off. However no beeps coming from motherboard just phase lights continuously on in the same configuration.
I've tried removing components (RAM, HDD, DVD) and booting just with the mobo, CPU and PSU, and same thing happens. There are no shorts (I've pulled the mobo out and tested it on a piece of cardboard) that are obvious and I have tested the PSU with a multimeter and everything seems to be in tolerance levels. The speaker is connected to the mobo in the right configuration but I haven't heard single squeak from it even with the memory removed which would suggest motherboard problem.
The big questions is... Which component is at fault here? No beep would suggest the motherboard but then again why did the computer shut off after connecting the graphics card? Also would a faulty CPU cause a lack of beep? The only troubleshooting pointer on the motherboard are the phase lights which I could not find any description for in the manuals or on Gigabyte's website.
Any help would be really appreciated!
Thanks
