E530 Thinkpad possible bad Motherboard?

Windows 7
6GB RAM
i5-3210M 2.50ghz
SSD

Hi, So my laptop has been getting slowly worse over the past 6 months. It runs fine most of the time but then sometimes when I put it to sleep at, say 40% volume with headphones in, when it wakes up it shows 100% but is clearly still at 40% and there's no way to change that. Sometimes it fixes itself if I sleep/wake it once or twice but usually I have to restart and the volume shows correctly again. The same goes for the brightness level, but not very often.
Lately it's gotten worse. One out of like 20 times I put it to sleep, it gets stuck in between sleep and wake with the screen off but the power light on. At that point I have to force restart and most of the time when that happens it doesn't Post the Lenovo screen right away. It's delayed anywhere from 10 Sec to a Min but eventually starts but sometimes runs a little slow as a result. I've tried the following many times:

-Starting without battery
-Starting without AC
-Starting with stick 1 Ram in slot 1 and slot 2 and vise versa with stick 2
-Starting without the SSD
-Removing the battery/AC and holding down power button for 30 Sec (many times)
-Leaving the battery/AC out all night

None of those things make any difference. Sometimes if, while it's trying to Post, I restart it several times, It'll startup like normal but that's been working less and less. The overall solution has been to let it startup in it's own time. Also, when it does the delayed startup, the wireless card will be set to turned off on it's own and I have to manually turn it back on. There is also a very slight electric feel when you brush your hand over the metal palm rest that's only there when the AC is plugged in. If I take out the AC it's gone, but I can feel that same electricity when I rub my finger on the end of the AC Adapter plug (DC actually)

I think that's everything. Sorry for the long post .

Edit: I noticed a couple things to mention. Now when it freezes while trying to go to sleep, and after I force shutdown, my external wired mouse's "laser" stays on until I unplug the AC from the laptop. Maybe a power issue related to the shock I get from the Ac Adapter causing this?
Also, when it does the slow startup after freezing, it takes a long time to post just the Lenovo logo, then after another 10-40 secs it posts the "Press Enter to enter into Bios" part, and hangs there for another min or so. Finally I get to the page where it asks if I want to do startup repair or start normally and after that it usually starts up at a normal speed.
Thanks for any help.
