Computer Won't Boot After Sleep, but Will Boot Directly from Drive Selection

Hey all, I don't know much about computers, but enough to be dangerous I guess, so excuse any misuse of terms.

I woke up this morning to boot my computer from sleep and it would not turn on, but the front LED was blinking as though it were still asleep. I did a hard reset, and when it went to boot I got the "Disc Read Error, Hit Ctrl+Alt+Del" and after rebooting again a couple times, I occasionally get a screen that shows the status of my hardware, and at the bottom (I think) is a message about some error with my CMOS (I don't know what it was exactly, I can only get that screen to pop up on occasion of resetting).

After some research I reset the BIOS to default setting, Cleared the CMOS with the jumper thing according to my Motherboard Manual, but it still won't boot after sleep. I found I was able to boot directly to my hard drive from the selection and am typing this on the computer I'm having a problem with now.

So, after a bit more research, it seems like maybe the battery for my CMOS is dead? I don't know, like I said I can get everything going fine, it's just after sleeping it won't boot.

Thanks in advance for any help.

Edit: Also, if it sounds like it is my battery, is there any definitive way to test this? Thanks.

A new CMOS battery (it's a silver coin-type battery, usually a 3v CR2032) costs very little so the easiest "test" is to simply fit a new one and then see how it goes after that. It sits in a round plastic cradle on the motherboard:

Turn off your PC and switch off the PSU with it's rocker switch or at the mains socket switch, but leave it plugged in to maintain an earth circuit (see why below).

Before touching any motherboard components or the motherboard itself, be sure to touch the bare metal of the PC chassis or the PSU casing for a second. This will purge any static electricity from your body which is potentially damaging to PC internals. The...

Before touching any motherboard components or the motherboard itself, be sure to touch the bare metal of the PC chassis or the PSU casing for a second. This will purge any static electricity from your body which is potentially damaging to PC internals. The static will discharge safely through the earth wiring (which is why you should leave the mains cable plugged in but switched off).

The new battery must be fitted with the '+' side face-up
