Gt640 is Supported by your motherboard no problem with PCIE but I would recommend you to go for AMD 7750 or AMD 7770

Then you don't have a power supply that is powerful enough, you at least need 400 watt for that

All graphic cards are backwards compatible. However, I don't think upgrading your GPU will make a difference. Your CPU, and computer for that matter, is pretty old. If you have the 640, that would be the max CPU that might be able to run with the c2d 4600. Honestly, I would look at doing a complete overhaul.

Well if it is a 350W its wont be a good brand. So it is a bad unit.

Go for Antec Vp450W for 30$ on ncix !

If you can hear it bette. Take you ear near the PSU and if the sounds come from there change it.

Also im sure it is the PSU. Its a 350 W PSU . Can you tell me the brand/model or read the label ?
December 2, 2012 12:28:44 AM

Antec Vp-450W 31$ ncix
Corsair CX 430 V2 35$ newegg

So just choose 1 of this and go game :p

No no no. What the **** is this PSU.

Get the one i told you. You dont need more W on that system.

Only if you go for high end PC (SLI/CF) you will need 750W

hey I plan to build another new cpu in this Xmas as well and this also my first time

here some information above it ,

MSI 970A-G46
AMD FX6100 3.3ghz
Kingston 1800mhz 8gb
Powerlogic magnum pro 535 max power 1000w (PSU)
WD 1.5TB
Samsung Internal 24X ATAPI DVD Writer SH-224BB
Aerocool Strike One PC Casing
Acer LCD Monitor S231HL 23-Inch LED 1920x1080

And a biggest problem is should i buy a new Sapphire HD 7750 2GB DDR3 or use back the GT640 ?
Can this works without facing any problem ??

Well that CPU is nowhere near I3.

The PSU is just garabge.

You can find a better case.

You dont need 1800 for gaming

About the GPU 7750 is better but i would go higher cuz you have a 1080P monitor where non of this cards can game with good FPS

why the PSU is garbage ?

The power supply market is rife with low quality units that do not deliver what they promise in terms of wattage. These low quality units also deliver very inconsistent voltages, which can cause damage to your components. The worst case scenario is if you overstress these low quality power supplies is that they will explode and take other components with them.

Powerlogic is not a reputable power supply brand. Any "1000 Watt" unit that sells for cheap is going to be a very low quality unit that can probably only deliver 500 watts at best.

The power supplies suggested to you above come from much more reputable brands. They deliver what they promise, and are much higher quality parts that are much less likely to fail on you.

So therefore which type of PSU should i buy and how much watt to run the system ?

as prototype mentioned earlier you will need
corsair cx 430 psu
or antec vp 450 psu.
first thing you must do now is change the psu to the one mentioned above as soon as possible and then try installing the gt 640 along with the latest drivers from nvidia and see whether your pc boots up.
i believe your current cpu e4600 should have no trouble running a gt 640 at all but first upgrade your psu and then try installing the gt 640. also dont forget to first un install the existing nvidia drivers and do a clean re install
