Short version: My computer wonks out and crashes if I try to oc gpu by even 1MHz
Hi all, when I bought my 4830 it could handle most of the games out at the time, albeit with some lowering of the settings on occasion. Recently however it's been really strugling with some of the games coming out, even on lowest settings. I plan on upgrading in the future, but it's currently not in my budget. Figuring I'd make the best with what I've got, I tried my hand at overclocking my card to try and squeeze as many FPS out of it as possible. Some people have reported some very successfull overclocking of the card, however when I tried to bump up the core clock by just 5 MHz in AMD Overdrive the screen goes black and my computer locks up! Then when I restart my computer the screen flickers every time I move a window and usually locks up within a couple of minutes. I then have to restart the computer at least a couple more times before it finally returns back to normal.
I thought that perhaps it was the softwares fault. AMD Overdrive seems to have a bit of a bad rep, so I then decided to give GPUTool Community Technology Preview 1 a try. It said that the current clocks were changing when I'd move the slider and apply, and I ran Find Max for both the core and the memory clock. The core clock went up to 750 MHz before it crashed, and the memory stabilized at 920 with no artifacts. However when it was running the test i noticed that the fps in the little benchmark test it opens up stayed around the same even when I set the clocks to 720/920. I thought I'd try it in a game to see how it worked and the game crashed on launch. I changed the clocks to 590/900 (575/900 are default) and the game still crashed. It would only run at the stock clock speeds.
I then decided to give RivaTuner a go. RivaTuner seemed to raise the clocks without a hich. I opened up AMD Overdrive just to confirm the clocks actually changed, and it said they did. I then ran the HAWX benchmark at clock speeds and then at 699/910. The FPS would always be about the same no matter what the clock settings. In fact raising the memory clocked seemed to slightly drop the FPS even. Are the clocks saying their changing, when in reality they're not? Is my card nearing the end of it's life? Is there any way to fix this and be able to properly overclock it? I'm sure it's not overheating because the teps rarely get over 60C.
If I can ever get it to properly overclock it I'd like to do a BIOS mod to it as well as shown in this thread:

Would doing a BIOS mod to it now perhaps somehow help to aliviate my problem?
I'm rather desprate here, can anyone please help?!
Specs:
Saphire HD 4830
4800+ Core2Duo
2Gigs DDR
750GB WD Black Caviar 7200rpm
Asus A8N 32-SLI-Deluxe Mobo
Windows 7 Ultimate 64-bit
ATI Catalyst Version 11.10
Enermax EG701AX VE(W) SFMA 600W PSU
P.S. I apologize for my longwinded-ness, I tried to include all details I thought may be useful for solving my problem
EDIT: Added PSU to specs
