This is boot error report:attachment added. I will try to fix the malware problem step by step...But this happened to me the first time in my life. After installing a game i had to restart PC.All went well and i passed bios setup normally.But when Windows XP had to come up,a dark blue screen remained like still booting.All my tries went boom,after i injected a bootable Windows XP instalation CD.Boot from Cd starts,blank screen continues.I fixed Windows boot section by disabling SATA1:My hard disk(Western Digital 320GB) NoW:All my games work normally.I cant open My Computer or My Documets.Control Panel is not opening also.I got the minidump since the last fail,i would post it but i cant acces any of two hard disk partitions. HELP!!!!!!!! And it seems this particular instability is making my PC loose overall speed.Not even Explore option enables me to see My Computer content.I cant delete icons from desktop in any possible way,neither can i rename them.It is strange that sistem crash is folowed by a VGA driver restart.PLZ HELP!
