Th diagnostic lights on the front panel read 3and4 which is consistent with a memory failure. I had a technician come out and reinstall new memory and it didnt fix the problem. Then he installed a new motherboard with my old RAM and everything worked like new. Now I have the exact same problem but I dont want to spend $400 dollars on a new XPS motherboard when ive already been through 2. I would like to build a new gaming computer with the parts I have and ru n another SLI configuration, and keep spending costsunder $1000. Ive considered upgrading CPU to the new i5 or i7 but I have a E6700 dual core at 2.66 Ghz so I really dont know if its needed. If you or anyone could give me a decent configuration based on my components and budget it would be gretly appreciated. Thank you so much.
