Agin, got a BFG 8800GT 512MB from OCuk on 31st october.

A mate who works for nvidia as a field technician put the card in for me @ lan a week ago, along with a 600W OCZ StealthXStream PSU, and Zalman CPU cooler for my AMD X2 5000 Black Edition.

My rig is on it's side, and my temps are now 42 degrees idle with stock fan at 45% via rivatune.

I have been turning it on, off, playing games, on, off etc all afternoon and finally it seemed to be stable.

I then shut down the pc, turned off the power at the plug and went out. Came back 2 hours later, turned on the plug, waited a few mins, powered up the pc and surprise surprise, the same 100% fan spin from my 8800GT, but no display.

Again i took it out, re-seated and reconnected the card, booted again - and it works.

Any ideas because i'm really frustrated now.

When it's on, it's awesome in terms of performance, and i know i could RMA but i'm keen to identify the problem just for the principal of it.

Also, i have no packaging anymore, will i still be able to RMA ? And what exactly does RMA entail ? Me going to the post office etc ?
 
I've done that everytime the rig has failed to display anything on boot.

I just don't know why it would work all afternoon, then not boot when i get home, no one has been in or touched anything etc....

Also, the pc is lying on its side so it cant be weight forcing the card to slide out of the pci-e slot ...
 
I can't see it being temperature related if it won't boot, I'd go through all your BIOS settings noting them down, then slacken everything off (fail safe) & try mains off restarts. Nothing to lose except 30 mins of your time.
 
Mine did the same sort of thing on cold boots 100% fan no boot, i would turn it off and back on and it booted, put your pci-express frequency on 101 worked a treat for me.
 
In my BIOS, the only settings i have that seem to be relevant are;

Primary Grahpics Adapter :
PCI -> PCI-E
PCI-E -> PCI

PCI Latency:
32
64
96
128
160
192
224
248

PCI Slot1 IRQ
PCI Slot2 IRQ

IRQ Resouce Setup
DMA Resource Setup

Bold shows settings that are currently in operation.
 
I got a Gigabyte P35C DSR and its in MB Intelligent Tweaker(M.I.T) and its called PCI Express Frequency (MHZ) Auto, i just set mine to 101.
 
Hi.
if you dont mind me asking. why do you turn the power off at the plug ? also if you just shut your pc down normal and DONT turn it off at the plug will it boot up ok ? have you checked your motherboard battery. is the time ok on your pc when you boot it up after you have turned it off at the plug
 
Am betting its the same that happend to mine tbh, exact same thing 100% fan on cold boots only and no bootup, i never turned mine off at the socket and still did the same, as i said doing what i said has solved my problem, there must be some setting for pci-e frequency in the bios.
