BIOS beeps when booting, RAM

[Jota]

Hello, I have this problem in my old PC
Windows 98 SE
Celeron 366
RAM: DIMM 32 MB PC100 + DIMM 128 MB PC133
Video: NVIDIA RIVA TNT2 Model 64 (Ver 4.12.01.0631 ,9/20/2000)
MOBO SOYO SY 7SBB.

Problems: Windows freeze, blue screen, windows explorer crashes.

Sometimes when any of these happens I reboot and the BIOS makes three short high tone beeps and two longer low tone beeps.

I took off the 32 MB RAM and relocated the 128 MB and now it seems to work. Before that I cleaned the registry and reinstalled windows with no luck.

Anyone please can explain if the beeps mean RAM failure or CPU (the fan is new because I had problems recently)?

Should I try to reinstall the 32 MB RAM or is it better to have the 128 at 133 and not 128/133 +32/100?.

I read in a page in this website http://www.computerhope.com/beep.htm
Any other beep(s)   RAM problem.

Thanks

do not mix pc100 and pc133

Yea don't mix those two sticks of RAM.  Also you don't even need the 32mb stick.  Windows 98 will run more than fine with 128mb of RAM.  I would toss the 32mb and forget the headache it could cause you.

Thanks people. I forgot to mention I used both modules for years.

Who knows, maybe now they started tofail. Anyway, I do not see much difference without the 32 MEG and just 128, so as you suggest maybe I just leave it this way.
