Apologies firstly, i have lost my old forum login details so i created another account. I bought an OC computer some years back and over the weekend i decided to switch out my Radeon 5850 Series to a Radeon 7950, which i thought may be easy enough....

Anyhow, said installation has encountered a serious problem, which hopefully you guys can help me with. Every time i load the computer, i get to the windows screen and within a few seconds the computer switches off. To try and resolve this i first thought it was a driver issue, so i started in Safe mode and reinstalled drivers. Though this did not work

Currently i have entered the BIOS/ Motherboard Intelligent Tweaker -Load Safe Settings, which runs the CPU @ 2.0 GHz, and everything seems to be working fine and windows loads up correctly. I also played BF3 for several hours last night and no crash.

However ideally i would love my CPU to be running at spec, which is 2.80GHz, so is anyone able to help with what i should do in the BIOS?:confused:

Other notes
Computer was clocked to 4.00GHz by OC, but i took this down to stock last year as it became unstable (Usually playing BF3...).

Switching the old graphics card back into the PC works fine.

Running BIOS optimal defaults in safe mode works fine too

I have never clocked a PC myself before, so no that confident....

Current Spec
Windows 7 64bit
Intel Core i7 CPU [email protected], 1995 Mhz
Corsair 750W
Gigabye X58A-UD5
Ram 6.00 GB
Radeon 7950
Samsung 250GB SSD (+ other HD for storage)


Thanks in Advance :)
 
At best guess I would say it's probably your power supply? While corsair do make good quality products this is the first thing that comes to mind. When you underclock the system and it uses less power you mention its fine. So maybe it's tipping the PSU over the edge? 750W is fine, but it could be spiking and dropping in power it's supplying to the system.

Don't suppose you have another one to hand you could try?

I had a similar problem when I upgraded my graphics card. Everything would power on but the system would shut down / restart and some times not give a display at all. Turns out my PSU was on it's last legs.
 
what bios are you running? i found f12 to be the best on my old ud5

try fully clearing the cmos by leaving out the motherboard battery for a good 30 minutes,then try

if its crashing in games it could be not enough qpi/vtt voltage
 
thanks for the prompt response :)

Solado - unfortunately i dont have a spare PSU, if there any other way i can tell my PSU is dying?

Wazza,

-on start up after the motherboard designation it says "F5", is that the bios version?
-What will F12 do?
-i have a clear CMOS button on the back of my pc, could i use that and how/what will it do?

Thanks very much :)
 
You could test the psu with a multimeter to check it's outputting enough power. Regarding the bios revision, load up cpuz and check the mainboard tab, bios revision will be displayed here. A new bios will have ironed out early problems with the board, and added compatibility for newer hardware.
 
Thanks Setter, i cpuz i have a bios version of F5, dated 03/11/2010, Award Software International,

I note on their website, they are on F8A?
 
f5 is an old bios,f12 was the last one I used before I sold my board

id update to latest off gigabytes site first,then see how it performs

you still might need to manually set qpi/vtt to 1.315v

newer bios's = newer fixes/improvements,to memory/cpu/stability ect
 
Last night i cleared the CMOS with the button at the back of the PC, but that didn’t make any difference, so i decided to flash the bios,

Incidentally I have a rev1 of this motherboard so the latest firmware is F7. Anyhow I successfully flashed with the @BIOS software which was painless.

At the moment the system seems to working fine, CPU is at 2.8Ghz, new graphics card is awesome. Fingers crossed it will stay that way!

Thank you all for you help, really appreciated :)
