Hello all. Have a k7vt2 mobo, Athlon 1800+ with single 128mb pc2100 pc266 184pin DIMM DDR SDRAM. Had a bad_system_config_info error. According to MS this means a bad memory module. Ordered 512mb, got 1gb pc2100u. Now neither new or old memory being seen by system, just getting 3 beeps repeated when powering on. Any suggestions on next step? TIA. Bill
