Dell Dimension 2350 Not Booting int

Specs: Windows XP
I am unable to boot into BIOS. Pressing F2 at startup puts the computer into some kind of stasis, with the ABCD diagnostic lights indicating: YGGY. (I can't find anywhere on the web exactly what THIS combination means.) If I unplug the power, wait a few moments and reboot, the OS (WinXP-pro) comes up normally.

I discovered this problem when trying to upgrade the memory from 2x128K DIMMS to a single 1G DIMM. The computer refused to boot, with exactly the same diagnostic light combination. After replacing the original DIMM back, it boots fine - providing I don't try to get into the BIOS.

Any ideas?

Is the RAM compatible ? Look here:
You don't hit F2 to get into the bios-try F1, F10, or DEL.

I have been assured (by the supplier) that the RAM is in fact compatible.

My intent was to upgrade the BIOS to A02, as it's the original BIOS supplied by Dell when the computer was first bought. If that didn't work, I was going to give up on the whole idea :-(

However, what concerns me is that hitting F2 during boot up puts it into some unknown state - exactly the same state as when the new RAM was inserted. I will of course, try F1 - thanks for that info.

Of course, I'm assuming that the 2350 will take a single 1G DIMM rather than needing 2 x 500 Mb DIMMs?

"I'm assuming that the 2350 will take a single 1G DIMM."
Look at the link-it takes 128, 256, or 512 MB Dimms.

1. I swapped out the 1Gb DIMM for 2x512 Mb DIMMs and got the same symptoms: YGGY.

2. F2 is the key to enter BIOS, not F1. (Pressing F1 at startup does nothing, and the Dell documentation states it should be F2.)

3. Pressing F2 takes me to exactly the same symptoms as (1). No BIOS, No boot, just the YGGY diagnostic lights.

4. The only recovery for this is to power down, remove the power for 10-seconds or so, and then reboot with the original memory in place. The the O/S comes up OK. (I think the BIOS must be stuck in quick boot mode, as no Dell splash screen appears - just Windows starting...)

I'm coming to the conclusion that this is a BIOS issue: Firstly, I can't get into BIOS, and secondly the Dell documentation suggests that if the hardware has change (ie, new memory configuration) it first checks the BIOS and then if recognizing a change, takes you to BIOS to configure the change.

My next step is perhaps to reset the CMOS and see if that allows me to get into BIOS. (My gut feeling is that if I can get into BIOS, I can get the new memory to work.)
