Windows 7: Bad power supply?

Bad power supply?

So I had put my computer to sleep before work today. I came home and couldn't get it to "wake up." So I powered it down with the button on the front. However, now it will not turn back on. It worked fine yesterday, I played some D3 and surfed the web... Tonight after work nothing. So I laid it down and opened the case and the green LED indicating power is ON(LIT UP) on both my MOBO and my power supply. However hitting the power button gets nothing, no fans, no blinks, beeps etc. So I completely disconnected my tower and took both sides and the front off and checked every connection. Twice. then I booted my Gf's desktop and started surfing. I stumbled across a few different articles.

How To Fix a Computer That Won't Turn On


Now I don't know. my thought is that my power supply is bad and is only sending enough juice to signal its got power but not enough to boot. but I don't really know and that's why im on here asking for youre help! Thanks guys!

I preach having a spare power supply to all my clients.

You should purchase a replacement anyway. Go for a Corsair with an 80+ rating with enough wattage (I'm thinking you need 800 to safely work with the gpu) to satisfy your needs. Swap out the questionable existing psu; see if that's it. Don't try to be frugal with those. Corsair, Seasonic, and Antec are the favorites with we hardware geeks.

Check the PSU with this and see what results you get.

Cmos??

I must admit that in all my double checking of connections, i failed to pull out my C-MOS battery. I did that today after my coworker suggested that my comp might be stuck in sleep mode. He said he had seen it happen before. He didn't provide any suggestions on how to fix this however. He claimed that it was a certain number of seconds holding the powe rbutton. So i figured i would try and pull the battery and low and behold it worked fine. it even resumed back to exactly as i had put it asleep! So thanks everyone for the views and the help!

A cmos battery is a cheap fix and glad that's all it took.

I bought another brand but the idea is the same. It just made good sense for me to get some basic test equipment in hand.

You needn't remove it to do the test I outlined, just pull the 20/24 pin main connector.
