4 beep sounds

Please stop trying to find a case that come with a PSU that can take GTX 750 card.
You are looking for trouble down the road.
Anyone who is trying to sell you that hp minitower that can do modern gaming other than solitaire is trying to rip you off.

Do not take my words for it, just do some basic research when it comes to PC gaming.
The beep sounds differ from motherboard to motherboard, usually the same if from the same manufacturer though. If you post your motherboard model and manufacturer the community might be able to help you more. You can also check your manual or manufacturer's website as it will usually have a page on what all the different beeps mean.
 
You might be out of luck unless you are willing to take a psu out of another HP dc5800 (correct me if this is not the correct model). According to HP's manual for the dc5800, 4 beeps means that the power supply is overloaded. The link below is the link to the manual, and I will copy and paste the recommended actions for posterity.

See page 64

1. Open the hood and ensure the 4 or 6-wire
power supply cable is seated into the
connector on the system board.

2. Check if a device is causing the problem by
removing ALL attached devices (such as
hard, diskette, or optical drives, and
expansion cards). Power on the system. If
the system enters the POST, then power off
and replace one device at a time and repeat
this procedure until failure occurs. Replace
the device that is causing the failure.
Continue adding devices one at a time to
ensure all devices are functioning properly.

3. Replace the power supply.

4. Replace the system board.

Good luck.
 
im pretty sure 4 beeps is the mobo timer non operational. this means either the mobo is dead or one of the expantion slots is falty. Maybe take all cards out but the gpu and see if it boots then. If it does put ther rest of the cards in 1 by 1 to see which one is falty
 
Right xxhappyxx, my one expansion slot is faulty.it is a ram slot.when I fit different ram sticks in that slot the CPU doesn't boot; so that's why I want to change the whole cpu. Not PSU so which CPU has a build-in good PSU of 400+ watts?That can handle my config???
 
Man.i hav c2d e8400 with gtx 750 which cause bottelneck on demanding games.and now my one expsnsion slot is faulty and my psu is also 300 watt which is not good..so i want to buy a cpu like i5 which can handle my config and has a good psu!!..so which CPU has a good PSU that can handle gtx 750 card and not bottelneck..is hp elit 8200 minitower is sufficient ? Or which?
 
I think when he asks which cpu has a build in good PSU of 400+ watts he means the computer?
and he says when he change his battery's ram, he means his mobo's ram

it's the only thing that makes sense.

Now to OP,
You need to take out the ram that is on the faulty ram slot to make your machine work right now.
If you want to keep your i5 2300, then you need a socket 1155 motherboard.
the cheapest one is MSI H61M-P31/W8 Micro ATX LGA1155 Motherboard from Amazon.ca. if you are living in Canada
If you live in the US, then the cheapest one is Biostar H61MGV3 Micro ATX LGA1155 from Directron

you can take a look at this http://pcpartpicker.com/p/Qv6Cbv if you live in the US.
Or http://ca.pcpartpicker.com/p/pNNLrH if you live in Canada

Also OP, please keep your component name right

CPU = the small square thingy that go into a slot beside the ram slot on the big rectangular thing.
Motherboard = the big rectangular thing that your CPU and ram slot and PCIe slot go in.
Computer = the entire thing that is probably at your side when you stare at a monitor.
Case = The thing that everything goes into.
Monitor = A rectangular thing that you look at when you are at a computer.
Battery = a small circle that goes into the rectangular thing (motherboard).
PSU = A big thingy with many strings hanging out of it whose end you put into the motherboard.


 
Also OP,
If I understand what you're talking about, and I am using correct terms:
Please understand that changing a CPU won't fix your expansion slot problem.
You need a new Motherboard for that.
Also understand that a CPU does not contain a PSU.
A cheapo bad case contains a very bad PSU, to get quality PSU you need to buy a quality PSU. You may keep the case.
If you want to upgrade from a Core 2 Duo please do not even think about a i5 2300. It is an obsolete product and unless you need a cheapo Computer that do office work (MS Words) and email.

If you need further help, please tell us your budget (money you are willing to spend).
