Which shop is selling Z97 OC Formula?

My PC (Biostar H81M-HG4 mobo) has a startup problem. When the main power supply at the wall outlet is just switched on, the PC cannot startup (like totally dead). Pressing the power switch has no response at all. After leaving it for 5 minutes, pressing the power switch will start up the PC.

What's wrong?

EDIT: Old coolermaster psu replaced. Now powered.

I have a H81M-HG4 mobo for my mom's budget build. When the PC is shutdown, my keyboard is still powered. When any key is pressed, the PC can startup. How do I disable it? I want it to be fully powered down.

Already disabled but it still can powered up via keyboard. That's why it's weird. I'm using PS/2 keyboard.

Finally sold by trusty Biostar TPower i45 which has served me well for 8 years.

When choosing a motherboard, I'm looking for these features:
- rock stable, problem free (I can't afford ant RMA. I don't live next to LowYat Plaza)
- huge-ass VRM heatsink (Malaysia is hot, so need the extra cooling)
- overclock champion in its family (ASRock OCFormula featured in IDF)
- good onboard audio (no noise when moving mouse / scrolling)
- no extra useless features which tend to jack up the price and kill itself (ROG)
- great reviews everywhere (including user reviews in amazon and newegg)
- reasonably priced (USD-MYR sucks)

Bought myself a ASRock Fatal1ty Gaming K6 for a new Skylake build (OCFormula reserved for N2-cooling taikor). Booted up fine with dual channel Corsair LPX memory and installed Win10 without issue. What a relief after hearing many bad Skylake-memory-bug stories (debug code 55, IRQL not less or equal, etc). Perhaps I'm just lucky. My last ASRock was an H81M-HG4 which I've built for my mom's rig. It was running perfect on first boot too.

Currently, the only drivers that I've installed are the INF chipset driver and VGA driver. In device manager, there's no exclamation mark (!) other than the Killer LAN (driver not installed yet).

Here are some cons/negatives that I've found (not that serious actually):
- coating on the board scratched off when tightening the mounting screw
- usb3 header not facing side-way 90°
- Fatal1ty logo on the PCH heatsink will look better than the robot logo
- user manual shows the wrong memory installation. unlike typical design, only 1 latch can be open/close. need a few try to seat the ram perfectly, else you'll get debug code 53.
- debug code led doesn't show temperature
- power & reset buttons don't light up all the time (remain extinguished after power up)


I hope ASRock (Pegatron) will continue to build great and well-priced motherboards in the future. Please don't end up like ASUS which has turned into a jack of all trade.

MSI M series. My old Biostar does show mobo temp (not CPU temp). I'm not sure of current Biostar models as I don't check out their reviews anymore as we can't buy it locally.

Most high end boards (MSI, Asus, etc) have headers at 90°.

Please check out the Z170 series.

Yes. Still facing the bug.
