ok heres another update in the life n times of my computer problems.........

it lasted 40 ish mins with a totaly diff (much less power hungry) gcard in it adn then did the same thing as before. totaly died as if someone had pulled the plug.....

i may cry

ok so im thinking psu, do you ppl agree or should i check the ram?

Well, you can still test the RAM first - run with only 2Gb for awhile and see what happens.

Note that it is the motherboard that signals the PSU to come one when you press the button.

well ok here goes. got home from work today and played around with the RAM in sticks of just ones. I put one in each time and it crashed each time , these were each put in one after the other into the first slot. each time it crashed I would try the next.

realising that wasn't to work I tried one in the secound slot,computer died again.so I tried a secound stick, with the same out come.

each test was with one stick in the machine and each time the computer died in the same way as before only this time its without going into a game the crashes were in desktop.

so its either the psu or the mobo,id sooner it was the psu.

what are your thoughts sir?

My advice ultimately is this: Replace the Ram that came with your computer (by this I mean put the original RAM back into the PC), whatever amount it is in whichever slots it was in before. While doing so check your motherboard model number, and get your PC model number if it is a "big box" computer (like a Dell, HP, Compaq, Sony, Gateway;etc.). You don't just want the brand name, you want the model number of the PC and this is usually on a sticker on the PC with its serial number.

If the computer was built you should only need the model number of the motherboard.

The point of doing this is to determine what type of RAM you need for your PC to work. You may be able to do this by looking at the original RAM sticks that came with your computer as well, I have never paid that much attention to them.

What I think may be causing your computer to crash after the RAM switch is that you may have inserted incompatible RAM or the RAM which you inserted is in total not enough to power the PC.

*NOTE: anytime you go inside your PC, you should have the power supply off and unplugged as well as any power conducting chords like an ethernet cable or any attachment to an external drive which is plugged into a power supply. Bleed the power supply by pressing the on button once all power conducting chords are removed. After this, open up the PC case by removing the side (you''ll have to determine what type of screw holds it in place and may require a screw driver of any number of shapes). Touch a piece of metal to ground yourself to the computer in order to prevent any static electricity from channeling through you into your electronic components and risking damage.

I apologize it took so long to get back to you, and more so, I apologize for not being more thorough in my explanation previously.

Make sure to put the original RAM into the same number of slots which they occupied before you started messing with them. After you have replaced those parts, try to restart your computer.

Does it startup properly?

well its not a pre built machine I built it myself a while back and all of this stuff started about a month after I put in a new gcard hdd and dvd drive. look back over the post and you can see where I am now and what we have tried to do . to try to solve this problem.

but thank you for your input so far

we think its most likely either the psu or mobo at this point I think ?

don't we digerati?

or the RAM which you inserted is in total not enough to power the PC.

Ummm, RAM does not power a computer.

Bleed the power supply by pressing the on button once all power conducting chords are removed.

Ummm, don't know what this is about. That does not bleed a PSU. ATX PSUs do not need to be bled.

I agree and I would try a spare PSU if this were on my bench.
