the system works perfectly fine. it just doesn't shut down completely.

there are no issues with the machine. it will restart when i hit restart. but when i hit shutdown. it goes through the shutdown procedure, and gets to the part where a normal computer will turn off after the complete shutdown, but mine will just stay at the black screen. the video card has been shut down, i know this because the monitor will receive no signal.

this n00b again, sorry I think I misunderstood your first post. Got a little confused with everyone else saying it was your PSU. According to this website it says your 465P-VE only has 20A on the 12volt rail. What does your sticker say? Does it only have a single 12volt rail?
I'm assuming your machine was shutting down correctly before you added the 4850? Do you have another PCI-E card to confirm this?

Good luck

the box that i received the PSU in says it has 33A on the single 12V rail.

and i remember seeing the sticker, and it definitely said thirty something amps.

the work that requires hardware removal i will do during the weekend, i don't have that much time at home with this specific computer these days since the computer is in a rack, and it would require a good amount of work.

it sound like a driver /app hanging during unload in which it is stoping you from a complete shut down.

boot into safe mode to see if it happens there as well.

33 amps on the 12v rail is not going to cut it with that setup.

I don't think it's PSU... Probably driver conflict... What card did you have installed before and what did you do to remove drivers for it?

Exactly, I run 51amps on my 12v rail and I have less computer then him.

well lets see i uninstalled the old gfx went in to safe mode and ran driver cleaner. so it should be uninstalled in theory.

then i downloaded the latest hotfix (i actually downloaded the hotfix before uninstalling and going to safemode) then setup the hd4850

my old card was a 7900 GT.

i don't think it would be a psu problem, i've had this computer running all day and no freezes or lockups have happened. it restarts just fine also. there are no random restarts or anything of that sort. -> but in order to test this i would need a larger PSU, but i don't have one around.

Your power supply is fine, assuming you're not overclocking your CPU to some excessive amount.

CPU is OCed at 2.65 Ghz

it was at 2.8 Ghz, but i tried it at stock 2.4 Ghz and same issue arose. i down clocked it to 2.65 for FAH temp issues

I found this and it looks like 32 amps.

Your PSU is border line for your setup OC'ed but it may not be the problem.
Did you use Driver Cleaner Pro when you switched cards?
