Hi,I have problem on my pc,my ram amount decreases,I have 639mb and DECREASE into 383mb,I really sad..how can I get back my ram..More info really would help!!

Explain what you mean and where you see these figures. Also - op system details, computer info and chronology of problem.

The figures also seem odd - RAM usually is based on increments of 256 Mb.!Ok2,today my computer have problem to booting then I get message like windows xp cant start because the file in windows/system32 has corrupt or missing,also Load needed DLL for kernal,I tried to restart,sometime It can boot but mostly can't booting..when It can booting,the start up is slow than before..then i saw my ram have 383mb..my computer have 2 ram combine,the one is 256mb and the one is 512MB,the total 768mb,but I check using properties>My computer it show 639mb,but now 383mb,the ram loose 256mb,any idea?No idea so FAR - properties should show total RAM in place and available .... maybe one of the other guys can get a feel for this.

I am guessing perhaps there is an actual RAM problem but others more knowledgable than me could well chime in here.

Might be worth knowing - how LONG machine been in use - any recent changes .. and has RAM been same all time? etc.I bought my computer at 2005,I dont know about ram at that time..my computer have 3 times damage..the ram decreases when the 3 times..from 256mb to 128mb,it make my computer very slow..so I combine with 512mb ram,the total is 639mb..but this ram decrease again 639mb to 383mb,it loose 128mb..very disapointed...now we are talking about MEMORY and not disk space aren't we?

Where are you reading these figures?Sounds like a bad stik of RAM...but as BC queried...where are these figures coming from ? ?
