Greetings all, I seek advice from the wise sages.
I have a Gigabyte H77-DESH motherboard, rev 1.1 with an Intel Core i5 3470 (I think) and 16GB Corsair Vengeance DDR 10600 RAM. It is installed in a NZXT Guardian 921B Case with a OCZ 600W power supply. The case and power supply were purchased used online. (NOTE: I purchased a new Corsair 750W power supply and the issues remained, but I did try a different and new power supply). The motherboard, CPU, RAM were all brand new. The video card is an AMD Radeon HD 4850 that was a hand-me-down from my bro upgrading (he was running SLI so I have 2).
The system build went smooth. Upon first bootup, I noticed things right away. After going into the BIOS and setting up AHCI, Windows 8 OS, PEG and primary etc., after exiting the BIOS, I had no video. I attached a D-SUB cable to OB VGA and bam...video. Went back into the BIOS and the setting for PEG primary was back to auto. Changed it back to PEG and I had video thru the AMD card via DVI. Shrugged it off as a one time bug and away we go.
Installed Windows 8 with no problems...until I went to restart. No video. Re attached cable to OB VGA and theres the video. Went back into the BIOS and you guessed it...back to Auto. Its almost has if it does not detect the AMD card. However, this card works flawlessly in an older Dell Optiplex. Also, the PCIe Gen setting currently set to Auto, although I know this card is PCIe 2, but should still work in a PCIe 3 slot.
Anyway, after fighting with the video again, I went back into the BIOS and disabled the OB video. Boots fine. Reboot, no video from DVI (AMD card) or DSUB (OB). Clear CMOS and start all over.
The point is, I only get 3 to 4 reboots before I have to clear the BIOS and start all over, which if you forget a setting, can wreak havoc with Windows (I have reinstalled many times, Win 7 x64, Win 8 Pro x64, and Win 8.1 Pro x64). Same results regardless of OS. Sometimes the OS doesn't even show the AMD card in device manager. Reboot (fingers crossed) and there it is.
The system is all air cooled with no overclocking. When the AMD card does run, it hovers around 40°C idle and 70°C under load ( I only play Diablo 3). I don think temps have anything to do with it as 3 other video cards (an older Radeon 4350, and 2 random nVidia cards). I wont even think about SLI right now.
Is the consensus that I have a bad board or atleast a bad PCIe slot? The top slot runs at full 16x while the other slot only runs at 4x. Also, I have noticed sometimes that upon startup or reboot, the system will totally power off, power on for about 3 seconds, power off, and start normal. Sometimes is doesnt do this.
At wits end...Help me Obi-Wan Kenobi, you're my only hope.
