I'm venting here because you would all understand! I Built a pretty good system- Asus M2A-MVP MOBO AMD AM2 6400+ 64x2 CPU 4 GB RRAM ATI Saphire HD2600XT 512 Vid Card Creative 7.1 sound 2- Lite on DVD Drive/burners 320gb WD HDD Front Card reader 600W Roswell PSU Its up and running for 7 days. Gets a 4.3 Rating on Vista and then ----Nothing. Turn it on and the fans run, the drives light up as well as the card reader. It just does not POST. I RMA the MoBo to Newegg and put the new one in and nothing. The HDD is dead! Sooooo..... I RMA the HDD to Newegg. Get it all together and It works great. 2 Days later Turn it on and Nothing....No fans, no lights-DEAD! Try a spare PSU and it turns on but will not POST. Fans run, drive lights work etc. Just won't POST. I guess the PSU was bad in the begining! So back to square one. I am RMAing the PSU to Newegg, MoBo to ASUS and the HDD...I will test that tommorow when I get home. It's been a great ride!
