Let me start this off with the specs of my dust collecting PC (which is probabaly due for an upgrade, and will be in a later post)

Im running dual Nvidia Geforce 8800 GPUs
on a GA-M750SLI-DS4 Mobo (was bios F5)
with 2 2GB Fatal1ty Pc2 6400 ram sticks
Powered by a Thermaltake TR2 600W PSU (Is this a reliably PSU?)
with AMD Athlon x2 64bit 5000+ CPU
my HDD is 500gb/7200rpm/16m Samsung HD5021J.
Windows 7 64bit. (havnt updated the OS for a year or so, left off with about 35 important Updated).
And i believe that is it.

So after noticing a difference in the computers performance...random crashes while playing games, temp freezes. I got some updated temp reading software and noticed that it actually hasnt been getting to hot at all CPU at about 100-115F while ingame, Standard for me. But the Dual GPUS seemed to be kinda running hot at about 120-125f in game. I monitored this for about 3 days and figured i could use a windows update and maybe even a bios update since it has been a little over a year. I cleared most unused programs did a disk check error for next reboot defragged HDD and all that good stuff and there was about 34 Important updates for my windows 7 64 bit so me being dumb trusted Windows i eventually did that also and quickly reverting back to my old system settings before the windows update. I did not like the nvidia Experience and all this 3D options which made my gpu run hotter and i lost some of windows features such as windows troubleshooter, the windows experience feature where you score the computer, could not view the network full map. So i did a system restore and figurd i could check out the Bios. ###BIG MISTAKE### I did not give myself enough time to gain the knowledge of how bad this could be if done wrong ESPECIALLY with @Bios Utility. I guess this is what you get for trying to get through things fast. Anyway, I used the @Bios Utility. Saved my old Bios on the desktop of the hdd and began to update F5 to F6 or F7 i believe. But from the charts i think it can only handle F5 only (Did not realize this until after). So during the Update it rebooted and seeing Post or Procedure Error and a timer counting down to start from default user so i fidgured my computer knew what was best and let it do its thing...Screen went black and nothing happeend after that. I waited around 30 mins and shutdown the computer. I somehow got the same screen to pop up and instead of selecting the same as the timer ends up selecting I remember hitting the select optimized settings and said yes to save to CMOS. After I havnt seen the bios and or any other image screen or color from the computer.

I did some trouble shooting on my windows 200 server OS and read about flashing, reflasinh, blind flashing, jumping the clr_cmos pins, clearing cmos with battery unplgged for an X amount of time. Power switching techniques that can tell the back up Dual Bios to come on but nothing thus far. So i had some time to start from the bottom and unplugged everything and chjeck to see what components might be faulty since i cant figure out the bios post black screen thing I I get only a few different responses from my computer. 1st is when i have the main cable to the mobo along with the 8 Pin ATX cable with no ram...I get One long beep and nothing else...The Keyboard may flash once when A/c power cables are turned on but unusable Which tells me the the CPU might still be good? But when i have almost all components plugged in the motherboard fans go on and all that like usuale but shuts down after 20 secs. So this tells me the PSU might be bad? The mobo capaciters and everything look fine but usually the lights on the network cable stay lit but not anymore, not sure if thats a psu or mobo problem. And that is where im stuck at. I tried to use a USB drive and floppy disk ...but not sure if i did those correctly, i jsut extracted the F5 bios onto each one and before that i formated them to Fat32. Ummmm yeah so im thinking either a Psu Mobo problem but dont really want to end up getting what i dont need so some feed back would be great.

*Update...So I plugged main jumper and atx caple to mother board along with the dual graphics with 2 ram sticks and just 1 keyboard. It does not turn on unless i trade the 12 v ATX cord with the 12v PCIe cable that i have plugged in for the extra power for the dual gpus...but if i go minimal it starts up....PSU sounds bad to me but...will that cause me from not recovering from the failed bios? Or is it now a paper weightand need to get both PSU and MObo...Next i will mess around with a meter and poke around and get some readings and update later.


P.S.Also last night i was doing a little bios homework and came across this amazing site that everyone should check out...http://www.biosflash.com/index.htm...has really good info and guides you can follow...
