Please HELP

Hi,

almost a year i can´t get off my PC the blue screen of death: Hardware malfunction....system has halted. Without any additional information i have to restart system, sometimes 5-6 times. I have read some threads about this problem, now I hope, I am at the right place and in good hands. Me and my friend, have changed HDD, Powersupply, RAM in my PC to find a reason. I have AMD athlon XP 1,5Ghz, 512RAM, 40GB HDD, LG DVD-RW, LG CD-RW. Have 2 USB slots, 1-Draytek modem, 2-USB Hub. I would appreciate very much your help, Last week I wasn´t able to work on my PC, because of this problem. Can you please have a look on my minidumps? I found 3 of them and renamed it to txt. maiki. Please any answer here or to my instant mail: mibartko@post.sk
