All Types of Hardware problems

I have a Pentium-D(2.8Ghz,800Mhz),2GB ram,DG965RY Motherboard,Palit ATI 4670,Intex tv tuner card...

I used my pc from last 2years but there was no problem...after I change my card to 4670...still all okey....but from past 2weeks somtimes my pc turn off without any notification..but still I can play Far Cry2,all latest games finely...

Now,My smps is a 3years old IBM Thinkcentre branded SMPS...it has 3 sata,2 normal power connector,1x24pin motherboard connector,1x4pin cpu connector...but I dont know my wattage..as it is not written anywhere...but after searching the internet i recently found that it may be 250watt or 300watt....my cpu connector is became black for burning...should i change my smps...I am confused????????

I also had this problem. But after i changed my SMPS to 650 volts its okay. Change your smps

PSU is the culprit out here. Get a decent PSU & it should have no issues. Act quickly before you end up blowing one of your components.

@ jojothedragon & Ethan_Hunt

I am going to replace my old PSU with a Coolermaster-500watt ....is it ok...or I have to take higher wattage?????....I think 500watt will be more than enough....My config written here..plz reply fast.........

Calculate ur PC power and find it out urself what PSU power u need.

else

u can go for Corsair VX450, without any ifs or buts

yes I calculate & it shows I need 300watt..so now I am sure for me 500watt is more than enough..I cant take corsair as it's costly......

^^^ since ur investing in a goos psu i wud suggest u to atleast go for a CM 600W.sud help u with ur future upgrades.

then he can spend on Corsair VX450 too. you really can never determine what is enough.
Even Coolermaster 460W is good enough for his rig.
He has already bought a new card. So I do not think he would go for any HD4850 or HD4870, any next upgrade for him would be whole rig change.
Only upgrade which is possible for him would be he starts adding HDDs, and they would easily hold 2-3 HDDs.

@ acewin

yes u r right I already did a lot of change in this PC...so there is no furthur change except a 250GB HDD..but that will be external..I will take a whole brand new totally highly configured machine in the mid of 2010 after Windows 7 launching...till then it is enough for me...

A

well if that be the case, then you should decide how on the upgrade would you go.
A Corsair product has very long lifetime and warranty. ANd I will second hellgate(when it matters to upgrade alot many things count).

But if you would like to keep in this system for just browsing and all then 460W or 500W PSU is more than enough, and you will be buying one again
