I have experience building PCs, although I never before had to build a system with such a complicated setup. I bought all these components myself (some of them used, such as GPU, Mobo) and assembled it all.
CPU: AMD Phenom II X6 1045T (2.7GhZ stock)
Cooler: NZXT Havik 140
Mobo: ASUS Sabertooth 990FX
Memory: Corsair XMS3 4GB 1600MhZ (x4 for a total of 16GB RAM)
GPU: XFI ATI Radeon HD5770 1GB
Case: Generic 'Gaming'-grade MidiATX with 4 included 120mm fans.
Power: Arctic Blue 850W
HDD1: Adata SSD S599 128GB (2.5" inch) *
HDD2: Samsung SSD MMCRE28G8MXP-0VBL1 128GB (1.8" inch)
HDD3: Hitachi HDS721010CLA332 7K1000.C 32MB cache 7200RPM 1TB (3.5'' inch)
HDD4: Samsung HD154UI/VPK Spinpoint F2 EcoGreen 32MB cache 5200RPM 1.5TB (3.5" inch) *
OS: Windows 7 X64 Professional*
Other: Generic Multi-Card Reader/ eSATA combo
When the PC first powered up, I got a memory error (according to the Mobo manual). I quickly realized a RAM module was incorrectly placed. I then got a Video error (again, according to the Mobo manual). I removed the VGA and I tried again, and this time I got a 'Hardware component failure' according to the Mobo manual. I tried removing all HDDs and SSDs, to no avail. Even with the system down to the CPU + Cooler + RAM, I still get 'Hardware component failure'.
What could be wrong with this set-up? Is there anyone who can probably help me find out what is wrong? I just hope that it is not a motherboard failure.
I would try each ram stick one at a time in each slot closest to the cpu. If the system posts, go ahead and load windows with just one stick of ram. After windows finishes loading, check each stick of ram with memtest, a free download; one of my boards even has it in the bios. Use only your boot hardrive to load windows; you can install each drive one at a time and let windows configure it for you later.
