Hello.

I recently bought HTPC:
- GA-Z87N-WIFI (rev. 1.x)
- Intel i3-4330
- G.SKILL DDR3 4GB 1600MHz DUAL RIPJAWSxCL9 (F3-12800CL9D-4GBXL)
- Samsung 840 EVO SSD 120GB Basic (MZ-7TE120BW)
- BE QUIET! PUREPOWER L8 430W CM (BN180)
- FRACTAL DESIGN NODE 605 (FD-CA-NODE-605-BL)
- Windows 7 Ultimate
(- no external GPU)

I've installed the freshest drivers from Gigabyte site.

It is connected to TV via HDMI and it works pretty well, but I encounter two problems:
1. It is on all the time, but sometimes when on TV I switch to its source (HDMI2) I see nothing - even if I plug out and plug in HDMI cable. I'm sure it runs - I can connect using Remote Desktop or TeamViewer.
2. It seems that sometimes it doesn't reboot properly: Windows shuts down (it can be seen in system event logs), screen turns black and that's it. HTPC still runs, I can hear working fans, but BIOS screen doesn't come nor Windows screen appears. Device is not seen in LAN. To fix this I must manually turn off it and turn on. Normally (on idle) in consumes about 35W, but I found out that after this "fake reboot" it takes about 55W all the time.

Those two issues happen on freshest BIOS (F5), and on F4.

Thank you very much for your help.

Hi there,

I'm not sure why you are having these issues but I have come across similar issues before. The thing to do is to try and find out the root cause of the problem and that is always easier said than done.

In an effort to troubleshoot, have you tried running your RAM at 1333MHz rather than its rated 1600MHz? Sometimes this can help and it is worth trying if only to eliminate this as part of the problem.

Looking at the User's Manual for this motherboard, Gigabyte recommend a PSU of at least 500 Watts:
Quote
To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system.

If you have access to a different PSU it would be a could idea to try that as this can be a major cause of BOOT/Reboot problems as the power draw is usually at its greatest during this process.

If you are using external USB Devices (apart from mouse/keyboard) try powering them down or removing them to see if they are causing the problem.

Check Power Saving Options in Windows and/or any Power Saving Software installed, to see if it is responsible for the monitor shutting down.
Remember, when all else fails a cup of tea and a good swear will often help! It won't solve the problem but it will make you feel better.
