Yes I tried this BIOS and works fine for me. When a newly released BIOS is found to be defective, it is withdrawn from the website. Sometimes they are withdrawn after only few hours, like version 0034. So if you want to be sure that it doesn't cause any problem, wait some time before upgrading, like 1 week or even 1 month.
If your computer locks up, or stops responding, it is very unlikely to be a BIOS problem though. You can try to upgrade just in case, but most likely this is due to other causes, like the CPU not properly cooled, or the RAM not set to the right voltage, or the system is overclocked. BIOS settings might also be the cause.
