I could use a little help with this nagging issue I have with my computer that I built myself.
Everything has been fine for years until the PCI-E slot of my last mobo died and I replaced it with an MSI G41TM-E43 with my Core 2 Duo 1.8 processor. I have 2 sticks of RAM - Corsair, 1 gig each.
It worked fine for a bit but lately the CPU has been in dangerous territory temp-wise and I realized I may have neglected to reapply thermal paste - so I went back in and did that today. However, upon rebooting - had the same issue as before I had the mobo - no signal to the video card - so after testing a million things, went back to Fry's and got another motherboard.
So everything is fine - everything was put back in perfectly... however now - my computer will only boot up with one stick of RAM in. I've tried both sticks - in either slot and it will power up everything - but when I put both in - the computer starts up, shuts down, starts, shuts down, etc..
Could I maybe have something off with my power supply? something not connected right? I've made sure everything is exactly how it should be. I am using a 650w Cooler Master power supply that I purchased about 3 years ago. Also, the only thing plugged into a PCI slot is my Wireless-N card. I'm using onboard audio and video.
Any help or ideas as to what it may be will be greatly appreciated! Thank you!
