PC shuts down suddenly !!! HELP !!

[aloodum]

@@ SKillz: If you can plonk in some cash, i'd advise this the correct time to move away from the Core 2 Duo..the C2d simply isnt cut out for the job any more.You will re-use the ram and if possible ask for any lga 1155 socket board as RMA assuming you have warranty ...already 775 boards are rare and by chance mayybe the rma centre will be willing to give u a current lga 1155 socket mobo..Poochne mein kya jaata hain ?
Sell off the C2d and get a i3 2120/2100

Incase you have to stick with a 775 soln, well the g41 S2p is the only thing thats available for 775 ,ddr3

And for ur psu, i assume its the stock version with a single pci-e power connector.Yes it will suffice

@aloondum : I am willing to give extra money for better board same socket lke P43 or g43, if he agrees but chances are very slim .. i even planing to change my procy to quad core may be if i get a good second hand deal...any how i am changing my whole pc by mid next year so i just need to squeeze it some how

wokays...but`ll there's no point in spending xtra for a premium 775 solution..just get a plain jane g41 and chug away till next year.

@ OP - heard lots of issues about FSP Saga II 500W - so if you need to upgrade something change the PSu and get something like Corsair GS600 @ 4.8k

i am little worried.. coz PC was running fine for last 4months as soon as i put 460 its dead in less den a month.. Is it coincidence or related to gfx card ? Btw i use my PC heavily.. i do gaming as well as heavy work in MAYA.... n I put it on download almost every alternate nights..

Yea i am looking to change my psu but not immediately as i want a new HDD badly... so can i wait a bit?

@ aloodum : i will ask for better 775 soln as i am afraid this might happen again... otherwise i have no problem with this board.. i dont know its stock or not its MSI 460GTX Cyclone Ed 1GB (*www.msi.com/product/vga/N460GTX-Cyclone-1GD5-OC.html)

^^^ mate theres no gurantee that a premium product wont fail as soon.Take in to consideration 2 factors:
1. You chances of getting a new rma-ed premium 775 board is close to nill..Its EOL for 775..no wonder rma centres will be lacking the same.
2. Even budget boards have decent build quality...Most of them use solid state caps and decent VRM, a far cry from the bloated electrolytic capacitors we saw in earlier budget boards(Criminals: biostar,mercury right down to the g31's )
Regarding ur gpu, if it uses a single pci-e connector then your well within safety limits.

FSP SAGA II is a budget smps,, IIRC it has a dual 12V rail...12V1 for CPu/Aux and 12V2 for periperhal devices,pci-e, with each rail having a definite current carrying capacity. To get an idea about actual draw, look for the 12V total wattage and divide by 12...thast ur total draw..say its written as 384W..dats 32 Amps..32 amps divided on 2 rail...I assume say 18A on 12V1 and another 16A on rail2.

Now since you have a c2d 2.13, its not a real guzzler, so ur V1 rail will have a low amp draw, while ur card and other componets(howsoever low) will draw everything from the secondary rail...
That means your 2nd rail is always loaded with demand from GPu and ur drives..even if say the load current needed was 19 A, the second rail wont be able to deliver more than 16, while V1 rail is still sipping cola on the beach
This leads to triggering of the over current proction on that rail..result shutdown

Bad Design? You bet and it happens.. Just because your card packet says 26A needed on the 12V and your PSu reads 12V1 14 +12 V2 14...its will comply..nopes
that 26A is the system wide specs..like gpu sir saying "okay let cpu sir guzzle 6 Amps but i want bloody 20 A on what eva bloody rail you are feeding me"

And not helping your case is that even FSP's higher end products havent got a good review..like Everest..they have been known for cutting corners by mixing capacitors from unknown low grade suppliers and others...

Check if the RAM is inserted properly if it dont solves then your PSU is the culprit try changing the PSU of your PSU with yours friends/relatives and check if its working

@aloodum : they said they wont be able to provide any other board on this solution.. So m cool with it, it will take a week or so. but i need to figure it out what was the problem so that it doesnt happen again..
btw thanx a lot for the detailed information regarding power distribution..

Well i have looked into FSP box it says total +12V1 + 12V2 Max output is 408 W, V1= 18A, V2 = 18A.
I also looked into card packet it says minimum req is 24A.

So what are you suggesting basically is that i should change my psu to better as its not able to provide required power... m i correct ? but i have once started it with my old psu (local) without gfx card and same thing happen POOF!!! gone.. dead.. silent ...

@101gamzer : my mobo was dead so i already sent it for RMA today there was no boot no beep even if i took out ram, i have even tried to start up with other psu but same result.

@topgear : thanx for the suggestion...
