HDD could be the problem because I cant acess one partion on my drive. It has two partitions D and H , H has the winxp and I can expand it and see all the files. But C doesnt expand, nothing. Cuesor freezes (with the whole machine) intermittently and after a while the whole thing just hangs and when I power it off and try to rboot , it just wont come up. No messages, no nothing just a blue screen. i have to wait an hour or so to boot again, First I thought it may be heat issues and ran the HW monitor. No component reaches any dangerous levels.
