|That is a lot of reinstalls in a short time. Unless you know that you are getting malware/root kits, I would suspect hardware, possibly a bad memory module or a bad hard drive. You can test your memory with Memtest (burn to CD and boot to it). You can test your hard drive with the hard drive manufacture's utility also burned to a bootable CD and booted to. Run the longest test on the hard drive and let Memtest run through all of its tests. In memtest, any errors can mean you need to replace the memory. On the hard drive test, minor errors can usually be repaired by the utility, but major ones or too many minor ones, will mean the drive will need replacing. If you get repaired errors on the hard drive, rerun the test after a month or so and if there are new errors, consider replacing it retroactively.|
You have to be a little bit crazy to keep you from going insane.
