Right so, I've got somewhat of a major problem with my computer. Every half an hour or so it'll decide to simply shut down. After a while I managed to get my anti-virus to completely run through, and a trojan horse was found and removed. However, the problem continues.
The issue with this though, is that this even happens before I can reach the log on screen whilst booting up. I've tried reinstalling windows, but the system has then told me that I have no hard-drive attached, which is completely false. A clean install would be ideal, as I've backed up all the necessary files. Any help would be greatly appreciated.
Oh, and I'm running XP Home and the anti-virus program is Avast.
Sounds like a heat or PSU problem. Download HWmonitor click here and let it run to see what your temps are like. CPU should be between 40-55C on average. Also make sure all fans are running and not clogged with fluff/dirt etc
Thank you for all the replies. I've completely cleaned out each of the fans, and also ran the suggested program (HWMonitor). I have 'CPUTIN' at around 81C, and I can only assume that this is indicating the temperature of my CPU, which therefore is quite high?
I'll try using another power supply if possible, and see if this improves the situation.
