If the machine was returned to it original condition and does not work this means you are now looking at finding what you didn't return to where it was or you have to repair the machine.
Here's a thought. At 3 years that power supply has aged and if it's one of the usual 350 Watt PSUs I see I'd consider a new one before starting the upgrades. I'd add at least 100 more Watts for the new video card's needs.
We are having problems with our upgrades, We bought a custom made computer about 3 years ago, we want to up grade the RAM and Graphics card. We have a ASrock p4vm8 mother bored. we bought the ATI sapphire x1650 graphics card and a samsung RAM (1g DDR400 PC 3200e)
We are having problems with both, When the Graphics card and the new ram are installed we get colourful squiggly lines showing up nothing else. We thought it was the RAM. So we took it out. Then we get colourfull squiggly lines but they are spaced out and are vertical. So we took the graphics card out, put the ram back in then nothing at all comes up. WE checked all the slots for dust but they're clean. The people at the computer shop said everything should work with our mother bored.
What is wrong?
We are using windows XP
need more info just ask.
Can anyone help us please?!!
