I have a Dell Optiplex 760 small factor. A year ago, I needed to attach more hard drives to my PC, so I had to pull out its great processor and get a big motherboard and case. The Optiplex remained unused this time.
Last month, I decided to revive the Optiplex, so I bought a new processor for it. My surprise was the PC didn't boot, and the leds indicated "BIOS corrupt or missing". I bought another motherboard from ebay, and now I get the same code, so I'm suspecting something is going wrong.
Now I'm thinking about the processor... I bought the cheapest LGA775 processor I found because I thinked it will work: """Intel Celeron D 354J 3.06GHz/256KB/533MHz FSB SL7TY Sockel/Socket LGA775 PC-CPU""". I've also tried the motherboards with a """Intel Pentium 4 , 3 GHz, Sockel 775, 1 MB, FSB800""". are those processors suitable for my motherboard?
I'm so sorry for asking but I can't find a list of compatible processors.
Lots of thanks in advance. Best regards.
Dell OptiPlex 760 SFF supports Intel Core2 Quad Q9550, Q9650, Q9400, Q8300, Q8200, Intel Core2 Duo E8600, E8500, E8400, E8300, E7300 E7200 and E6550 processors. Please let me know if you need further assistance.
The discussions here should help you:
Dell does not recommend or offer processor upgrade but it is as your discretion in case you really wish to go ahead with it. Warranty per say, issues arising due to the upgrade will not be covered under warranty , however we will continue providing support for other issues and parts.
Hope this helps. Please reply if you have any questions.
Hi Saharsh and thank you.
Woah! I'm very surprised to see that processors with same socket and lower profile are not supported. But this was my error.
Let me do another question: do you guess that the motherboards are OK? Do you think it's normal that the error code is "BIOS missing or corrupt" when you put a non-supported prcessor?
You can have three main causes for a BIOS error: a corrupt BIOS, a missing BIOS or a badly configured BIOS. A computer virus or failed attempt to flash the BIOS could make your BIOS corrupt or delete it completely. In addition, changing the BIOS parameters to incorrect values may cause your BIOS to stop working.
If you are able to boot to BIOS, try resetting it back to defaults and check if the issue persists. If the issue persist you may consider replacing the hardware.
