Thank you again for your response.
You can replace the CMOS battery, it is located somewhere around the bottom of the board. ... Also, does it let you boot into windows, or is it stuck in the post screen?
I replaced the CMOS battery and on power up, there's a single beep and gray Dell set up screen comes up. Tried setting system defaults and setting boot priority to HD 1st and PCI/AGP card 2nd. Won't save changes yet.
Saving these settings after upgrading RAM, replacing HD, Graphics card and reinstalling Win XP last year about drove me bonkers. Currently log file lists Pre-Boot errors: CMOS Battery failure and Keyboard not functional. According to the manual's Beep Codes:
"POST Beep Codes
If the monitor cannot display errors or problems, during POST the computer might emit a series of beeps, or beep code, that identifies the problem. The POST beep codes are listed below.
Possible Cause Corrective Action
1 Beep A memory refresh failure occurred. Re-seat the memory modules."
It's very curious as the 2 sticks of RAM show up installed along with new HD & GR. Card. What do I know, will re-seat Bat. & Mem. and cross my fingers!!
