UPGRADING MY OLD PC....HELP

[SPEED94]

Hi ,
I am not a hardware expert so bear with me while I mention my specs before I state my problem.

Chassis name faded out .....probably a high tower...16.5"hieght

Motherboard....RC415ST-hm 1.0 (hp pavillion a1510y...could'nt makeout the ATX part )

HDD......Seagate SATA 160 gb 3.0 Gbps

DVD-RW....Sata

PSU...I did'nt care to check...I just wanna replace it

I think this should be enough for the problem I have..
So my problem is I am cut out so much for money that I can not afford more than 250$ but I still have to upgrade....
I wanna upgrade the processer/mobo/PSU/ram ....Is it possible on that budget...I have decided on a i3 2100 confirm
If its posssible than would it work with the old HDD/DVD-RW/cabinet ?
If its not posssible ...will cutting out the ram work...I can at max manage a 4gb ddr3 somewhere else...
I will be changing the other parts with time as I get money....
I do not wish rather do not expect too to overclock at that budget...so no P67/Z68/Z77 chipsets I guess...Just some PCIe 3.0 slots and support till i7-a must

Urgent help needed. thanks to all helping friends in advance.

1.Dvd Rw is your disk drive or your disc player
2.i7 needs a z77 chipset, so get a 3rd gen i3 which uses an z77 lga 1155 mobo.So you can just upgrade your cpu without buying a new mobo.
3.Your PSU support your gpu , mobo , and cpu's power or it wont work
4.HDD drives are basically all compatible, but you could upgrade since new ones might be a bit faster
5.You didnt mention a gpu, so you probably have an intel integrated cpu, so get a intel i3-3225.Not 3220, since it only has Intel HD 2000 graphics ( 3225 has HD 4000 ).Unless you are getting a non-integrated gpu.

Oh I did not knew about the i7 support on z77 chipset fact...Thanks...Then I guess I would leave away the i7 ...just the board should support i3 /i5/pcie 3.0 ...And that about the PCIe 3.0 because I would later as I get enough money fit in a HD 7850 2Gb but now at the moment with a laughable 250$ budget I can not even think of a HD 5450...FORGET THE HD 7850...
Please suggest a suitable motherboard and psu such that it fits in the 250$ budget along with the i3 2100.
I am reluctant on i3 2100 because that was the best processer i could find at that range....can not go up to i5 due to shortage of money and lost the wish of a AMD Phenom 2 X4 965 from the different perfomance reviews.Please help.

Since you're not getting a graphic card, instead of i3-2100 , get i3-3225 since it has Intel integrated HD 4000 and has Ivy Bridge.Its about $145.

I3-3225
Pros:
-new 3rd Gen Intel processors
-Ivy bridge
-Intel HD 4000
Cons:
-$25 expensiver

P.S.
Ivy Bridge is faster than Sandy
Ivy bridge has 3xxx
Sandy has 2xxx

For a motherboard, in case if you want to upgrade to a better processor in the future or get a graphic card or have cross fire technology...

$160

http://www.newegg.com/Product/Product.aspx?Item=N82E16813131848

Then for future graphic card...

$70

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139028

for about $230 minus $25 ~ 35 for i3-3225

However if you mean to get a cpu , motherboard , and psu for all under $250, then....

motherboard: $125

http://www.newegg.com/Product/Product.aspx?Item=N82E16813131832

psu: $45

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139026

for kind of $305 together, but its worth it since you're not going to get a graphic card which costs an extra $150.

P.S.

Though if you are going to get a graphic card in the future, the cpu will support it though you might have to upgrade your psu to the 600w one.

Thank you so much for the review...with a month's more savings ....I think I can go up to 305$ !!!
