Thanks in advance guys for any info. So I had my computer on for the last two days, untill yesterday night when I decided to turn it off. It was working fine. So I wake up today and turn on my computer. I reach the internet, and all of a sudden it shuts down. I was like WTF!!!! I turn it back on again and it gets past the bios, and shuts down again. It did this all the times i tried turning it on. Sometimes it would reach my desktop. I have Thermaltake Tidewater Liquid VGA cooler, and I also have Liquid cooling on my PC from Alienware. So it cant be overheating. Any suggestions guys. Could it be the PSU, or do you guys think the timing on the Memory might be out of whack. The PSU that came with my computer was a 650w PSU with 6 pin Atx connector. The one I replaced it with was a Thermaltake 500w with a 4 pin Atx connector.
