I don't know where the problem lies, but my computer's time keeps changing.
When I turn on the computer, the time is wrong. I just changed it to the
right time, 1:50am. Last I looked it was correct and said 1:32am. It is
currently 1:40am, and it now says 1:07am. Any suggestions? Oh, and when I
first start up my computer, each time, it won't but i hear the CPU, and i
have to restart a second time.

You might have a flat battery. Here is how to confirm it:
1. Reboot your machine.
2. Get into the BIOS setup. On many machines you need to
press the Delete key early in the boot sequence in order
to get there.
3. Set the correct time.
4. Wait 30 minutes.
5. Check the computer time. If it is correct then your battery is fine.
If it is wrong then you need to replace the battery. It is usually
a button cell installed on the motherboard.

So, if I have a laptop, I probably won't be able to do it myself? Does it
matter if I just let the time be wrong until, say, May?

Didn't you miss a step or two?

3.5 (!) Turn off computer and disconnect power lead
.....
4.5 Reconnect power, turn on, and boot back into BIOS setup.

If you do exactly as you suggested, the system's RTC remains powered
from the mains throughout, and should keep the correct time, even if
the battery is dead.

Please respond to the Newsgroup, so that others may benefit from the exchange.

I'm trying to vary only one parameter at a time. The OP reports
that the time changes while the machine is powered up. My
test maintains the powered-up condition but it knocks out any
influence from the OS. Your test, while perfectly valid, would
vary two parameters: It removes Windows from the equation,
and it also powers down the laptop.

How about running the test I suggested before
speculating about any subsequent action? The
test result might point to something other than
a dead battery!

It's often very easy to replace the CMOS battery in a laptop. You should
be able to research how on the laptop company's website. Just having the
time go wrong isn't so bad, but when the battery goes completely flat and
you lose other settings for the CPU and drives, then you'll have problems.
 
Actually, given the "need to restart" or "double start" the unit to get
it to boot tend to point to a flat CMOS battery.
