Ok, so I recently upgraded my GPU from a 8800GTS to a HD 5850.
When I try to boot it, 4/5 times it tries to boot (fans spinning, dvd drive/HD working, etc) but it doesn't post. Occasionally, I'll get past the post and the system will boot up and windows will load fine. Once it gets past the post, the system works fine. I originally thought that it was a PSU problem, but after ordering a new PSU the problem is still there. When I replace my new card with the old one, the system posts and boots fine. I'm not sure exactly on the PSU requirement differences, but I tried booting with a friend's 6850 and it worked fine.
My question is: could a faulty GPU prevent post sometimes but work fine once it posts? It really seems like a PSU problem but the PSUs I had were 700w and 750w respectively and the card only says that it requires 500w.
Again, what I've tried:
Old PSU + New GPU = Problem
New PSU + New GPU = Problem
Old PSU + Old GPU = Works fine
New PSU + Old GPU = Works fine
New PSU + Friends GPU = Works fine
I plan on trying the new card in his system later today.
The rest of my specs:
Motherboard - http://us.test.giga-byte.com/Product...ProductID=2553
CPU - E6600 overclocked to 2.7ghz
4 Sticks of Ram
New PSU - http://www.newegg.com/Product/Produc...82E16817139006
