Either my power supply or my GPU is dying, need help diagnosing
4 replies, posted
So here's my problem: about a month ago, my computer started to randomly lock up and get weird artifacts when it locked up, best described as green and red tears about 1 pixel wide that went from the top to the bottom of the screen. The screen was also dimmer and it looked sort of like the screen was offset by a few pixels and made transparent (I am going by memory, this has not happened for a while).
This went away, and now recently my sound has been cutting out, and even more recently I have been having random shut downs. The computer shuts down without warning. Another peculiar symptom is low framerate in games that I have had excellent framerate in just a week ago with the same settings.
Please help, I really appreciate any help and thank you in advance.
Specs?
Motherboard is Foxconn P45AO1
Processor is Intel Core 2 Quad Q6600
Graphics card is 8800 GTS 512
I use windows 7 64 bit as my OS
I have 8 gb of ddr2 G.SKILL RAM
My soundcard is a Creative SB X-fi
I don't remember what brand power supply I put in when I built my computer, but I am pretty sure it is a 500 watt power supply. I don't remember how much it was.
Hopefully this will help, if you need anything specific please ask
Red and green shimmer pixels are typical of having a PCIE slot or GFX card get overvolted; which potentially means it could be both. Get a utility and underclock and volt your card, and compare screen states.
I suspect it's your Gpu
But do what above poster said to confirm that.
