I've been using my PC with H55M-S2H mobo on it basically everyday since I built it back in 2010. And just recently, for the first time, I didn't use it for three days.
And now suddenly, it refuses to boot. As mentioned in the subject, I get a bip-bip-bip-bip-bip series of short beeps and it shuts itself off, when I try to boot it. According to the user manual, short continuous beeps are indicating a "power error". However, what kind of error would this mean?
Any tips on how I should proceed with diagnosing where the power error is? Thanks.
