Hurrah! I want to shove my 8800 into an oven in a attempt to fix the blasted card. But here is some information first...
Why would a man of my class want to do this? also specs...
Motherboard: F690GVM
Ram: 4gb ddr2
Video card: Good ol' BFG Nvidia 8800GTS 512 based on the G92.

Why?

Well, I got a idea one day and decided to get the remaining 800mb of ram out of my system. So I installed Windows 7 Ultimate 64. Everything went as planned.. until it halted at the windows logo on the first startup.
I did the obvious move, restarted it a few times. Then on the last try my system clicked 4 times without running a post. Turned my system off for an hour. Ran HDD testing software on a floppy. All was well! I was no longer crying. Started it up, the 8800 refused to display. Tried my onboard with the card connected and the fans spinning. Onboard was somehow activated. Reset bios to defaults. Then I restarted the system and it decided not to post. Turned off system, removed the 8800, started up and it ran the post test then beeped confirming everything is OK.With all drivers installed, Marvell LAN etc.. Windows decided to detect a signal but not connect. Restarted system after installing ATI drivers, blank white screen with working cursor on my onboard video. Reinstalled windows 7 64, Same result... white screen movable cursor.
Now at my last ditch effort to revive my BFG 8800GTS 512 manufacturer OC. I want to bake it in a oven and see if my problem is a micro-something. Reminder, Fan spins normally. Just no post beep or display.
Ideas before I bake it?
I was thinking it would go good with mushroom soup.
If anybody knows anything about the toxic fumes going into the kitchen oven, I'm not to worried because it complies with RoHS.... which means no lead in the solder?
PM me when you record it.
good idea, I will record it so everyone can enjoy a video card being burnt... or maybe fixed? On the off chance it gets fixed for the next couple months means I can hold off on purchasing a 5770
Hahaha, Goddamn it James...
Are you going to at least try to fix it using the oven technique?
Worked for some guy on his 8600.
I think so, I have no other choice and it isnt really going to bring me hell, I am getting a new card for that old system anyways. Along with a new motherboard, CPU, etc.

Correct.
If there is a plastic piece that surrounds the fan to control air flow, take that part off first. Or else.

The only thing I am worried about is the thermal paste residue on the stuck inbetween some of the transisters next to the GPU. And some sticky stuff on the memory chips. I rubbed most of it off but I lack cleaning alcohol. So I cannot be exact. I really do hope the capacitors on the card are rated above 385 F. I am to lazy to purchase a heatgun... Though the oven will get me a all around heat which is probably better. I might be better off selling the card though. But meh.
DO NOT put the card in the oven, it will damage the entire card, even if it makes it work again.
60/40 solder melts at between 600-650F, and ROHS solder (which 99.9% of electronics from 2006 and later use) has an even higher melting point. Capacitors have a heat rating printed on them, which is usually between 85-105C (185-221F.) Putting the card in the oven WILL damage the capacitors, and basically everything else on the PCB.
All components are designed to withstand going through a reflow station, which is 600-700F, but they're only exposed to the molten solder for less than 3 seconds (usually less than 1 or 2) but an oven just cooks everything. Another danger is all of the toxic chemicals vaporizing and getting stuck inside the oven and contaminating food.
The safer way to fix a cracked BGA is to use a heat gun localized to the GPU only, and only for about 30 seconds to a minute without moving the PCB to dislodge the chip. There are people that specialize in BGA repair and have the proper equipment if you want to pay a bit for a proper repair.
Anybody know what
"746
s v p
180
16"
means on the top of a solid capacitor gets a winner rating.

Also, It is RoHS compliant.

And no, the melting point of RoHS solder isnt anything near 700 F. Atleast for the reflow effect I'm looking for.
The effect I will be looking for is 196 Celsuis. The 8800's can peak at almost 110C while gaming.
The caps are rated higher then 200 C
Not to mention almost all newer video cards do not use electrolytic caps.
"746" is either the line number or the MFG date.
"SVP" is the manufacturers' initials.
"180" is the microfarad rating.
"16" is the voltage.
Not all solders or ROHS solders has the same formula, some have extremely high melting points (nearly 500C), while others have relatively low melting points (50C).

Unless you have the spec sheet for the capacitors, don't automatically assume it has xyz heat rating. And just because it may have a high heat rating, doesn't mean the other components on the PCB also have the same heat rating.
Also, rating yourself makes you look dumb.

I know it does, I did that for the lols..
Also, I have heard of hundreds of 8800GTS g92's going into the oven. I don't see why this particular one will cause me any trouble.
I'll be cooking the card tonight. I'll report back.
