Am using Win XP Pro SP 2 with 2 x 256 mb ram.
Since the last more thn a week am facing a strange problem. This came to light when I got messge "No free space to save file". On checking propery of 'c' Drive I found no free space left.
I restarted the machine and on rechecking property of 'c'drive I found that all the free pace was restored.
Thereafter every moring on start up the used space is 5.81 gb; Free space is 14.1 gb and capacity 29 gb.
Even if I let the computer idle for few hours I find that the free space is decreased and used space increased. By the end of the day there is no free spaceleft.
Have to restart to regain free space.
Can any one of you help me to understand what is happenning?
Have trid scanning with online scnners and nothing is reported.
I eagerly wait to receive some help.
