Ok the clock thing is simple. open up the cover on your computer and look at the mother board (the mother board is the very large circuit board) look for a small flat battery that looks like one of the larger hearing aid batteries. then just take something small like a hair pin and pop that battery out (don't worry you wont hurt anything) also be careful that you don't touch the motherboard itself especially with your skin because your bodies natural static can mess it up.

then look at the set of numbers and letters on the battery and go to walmart and buy a new one then just pop the new one in. Ok that's fixed......

The only thing I can suggest for the other problems other then messing with the hardware is reinstalling your Operating System. (Note: this will completely whipe your Hard Drive so make sure to back up your files)

At this point they suggest you disconnect everything from your computer except the power cord, the monitor. and the keyboard and mouse (but I never do)

Insert your Operating System disc and power on your computer.
Tap F11 as your computer initially powers on until your hear a beep then you can stop.
Select Boot From Disc (or cd)
wait for it to load the hardware then press F8 to accept the terms of service
Based on your operating system the options will be different but it might say "to continue to install a fresh copy of windows press esc" it might be different but select the option to install a fresh copy.

you will see a list of hard drive partitions. select C: and press enter.
If available you should format using NTFS file system. if you don't have that option then select FAT32 and continue.
the next 30 minutes or so you will probabilly not have to do anything. it will be going through the install process which takes a while. but you should watch it.

the rest is pretty simple. if this does not fix it then I'm afraid it's the computer itself

Cheers good luck!!

Hmmm.... seems like you know a lot about this hardware stuff. Recently I bought a second hand computer from a relative who is very much interested in selling it. Here is the configuration

RAM : 1 GB/ DDR2
HDD : 500 GB
Processor : Core2Duo 2.4 GHz
Motherboard : DG31PR
Monitor : Dell LCD 21 inch
Speakers : Creative 2.1
Intex UPS

Everything for $300. Is it worth that much?

300$ that's cheap, so which brand you opted ? HCL ? or acer ? I think these are the only two with less prices in market. Or you assembled on your own ? That way price will come down for sure.

That computer is worth a lot more then $300 if it is in good condition and runs well
1GB of ram is really good. my computer only has 512MB RAM
Your Hard Drive is worth over $200 itself.. 500GB is insane!! are you sure that's what it is?
Your 2.4 Ghz prosesser is very good since most computers have 1.8 or around that. (mine has 3.6 Ghz)
The monitor and Speakers are also very good is they are in good condition

I'd say if everything works and it is in good condition you should be able to get around $700

on the other hand if it is custom made computer (made yourself) then it will indeed decrease in worth by a few hundred.

Cheers

Yeah! Yeah! Yeah! My deal is a good one. It's an assembled PC, one of my relative sold it for $300 only. I decided to buy it when he told me that he is going to sell it to somebody. I convinced him and made him to give that PC to me. I am very much satisfied with it. It's in good condition too.

@Soviet Rathe : Yes, it is 500GB, Seagate.
