I have a Athlon 2600+ on Asus A7V8X SE MB with 256 MB DDR 333MHz RAM OS is XP PRO SP2 For the past 1 month the PC freezes occassionally when slightly memory intensive work like running multi apps, audio editing & playing Midtown Madness bundled with Digit Jun 05. Once it freezes I restart & then too it freezes while running scandisk or during startup. Since yesterday its become very frequent & I can't do anything on it. Rt now it said It couldn't load the user profile (ADMIN) and sent me to default profile. Where too it froze when I ran chkdsk from RUN... as some files were corrupted & the bubble keeps popping up. Pl help me as I feel its some thing to do with the RAM being faulty ( its a yr old RAM) Check out the problems I have been facing:- Here's a summary of some more problems:- 1. NAV 2003 freezes when doing complete system scan. 2. Defragmentation of C: doesn't take place even after 2 hrs (10GB partition) It remains @ 10 - 15% 3. Recently an error has started cropping up after I close IE 6. iexplore.exe - Application error INSTRUCTION AT "0x0190e10" referenced memory at "0x0128ad58". The memory could not be read. Click OK to terminate the program. What cud be the prob. There's no overheating prob..
