I have had this problem occur to me twice, both of which at night. Last night I guess, the power went out and my P.C shut off, but the strange thing is I couldn't turn it back on (both times it happened) until I unplugged it from the power bar then into the wall. Then once it started from the wall I plugged back into the same spot in the bar and it booted fine. (Both my monitor and speaker lights were still on after the power went out which are plugged into the bar)
I'm okay with fixing the problem everytime it happens as the power doesn't go out normally, but I just don't want anything to be damaged either
I finished building my computer 2 months ago with a 1000w Thermaltake Toughpower grand gold psu.

The unplugging of the power cord may reset a breaker in the PSU from the power outage - this is to protect your PC when a power outage happens. If you really want great protection - get a UPS like this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16842101123&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-UPS-_-N82E16842101123&gclid=CjwKEAjwjKOpBRChjsTyicbFy3QSJADP1gTNzT5QuvpRR6sazsLFvRtw49EbTSkdhX5rUYrDmtLzJhoC-Lrw_wcB&gclsrc=aw.ds

It is a simple UPS, only giving you 5 minutes of power (plenty of time to shut down) - but when the power goes on and off, it won't have any effect on the PC. If you want longer power, you can pay a lot more for them....

Alright, that sounds like a reasonable explination, but when I unplug it out of the power bar then back in the same spot it still wont start. I have to plug it into the wall first

Fuse, short or burnout in the power bar? I take it by power bar you mean commercial or an extension cable with multiple sockets.

Does the powerbar have a light that doesn't light up anymore?

It could be the power bar. But the first time it happened I replaced the power bar with a used one around the house, but the same thing happened to it. Both power bars didn't have lights

Depending upon the power strip, they can be rated for anywhere between 5A and 15A for normal power strips (they do have higher rated ones, but they have different plugs on them). 15A at 110VAC is 1650W - that should be enough for the computer components, but with age and use, the power strip may not be at full efficiency - especially if they have absorbed power spikes in the past. With the missing lights - that would be a concern as to them being effective.
