Inability to manually overclock

My PC at work seems to have lost its ability to overclock. Here are the relevant specs:

CPU: E5200 (stock cooler)
Mobo: Biostar TP43D2-A7 (I know this board sucks)
Memory: OCZ Platinum 2x1gb DDR21066
PSU: Earthwatts 500
Vidio: 8400GS
O/S: Vista Business

I used to have a S1283 cooler on it, and I was able to run it at 3.5GHz without any issues. I have since removed it and just ran it at stock speeds for the last couple months. However, now when I try to overclock it by 1MHz, it won't even post. Even underclocking won't post. I can change the memory timings without any issues, so I don't believe that is the problem. The only other change I have made was replacing a HD4670 with the 8400GS. I have overclocked a few 775 mobos, so I more or less know the main issues with BIOS settings.

My biggest issue is that I can use the auto overclock to run it @ 2.75 without any issue. Everything is less than 2 years old. Any ideas on what to check?
 
Have you cleared the BIOS at all? Completely remove power and pull the battery on the mobo. See if that helps.
 
Tried pulling the battery, but it didn't change anything. I assume it has to be something stupid to prevent even a 1MHz change? And my PCIE is locked @ 100 (tried 101 as well, didn't help).

Well you dont want to change the PCI-E so thats a good thing.

I know...but I was just saying it before someone said that could be to blame...I'm glad I don't really do anything too taxing, so 2.5 vs. 3.6 isn't that noticeable.
 
I think any CPU, even the worst ones, could successfully overclock by 1 MHz. Can you RMA this board?
 
Well I know the CPU used to OC...do you think they will RMA it if it has no other issues than me trying to manually overclock? I would think that wouldn't be covered.
