Solve : pc-restarting by itself?

Answer»

Hi all. My problem with PC, Windows XP, SP2. It had either restarted by itself, or got frozen or blue screened so I had to restart it. I dont know exactly when it started I forgot. Today I decided to format it. I transfered all data to external hdd and formatted it. Everything went smoothly during the formatting. After that I INSTALLED drivers for motherboard and for VGA. After I clicked finish for the latter driver the cursor got frozen. I restarted several times in normal mode and once in safe mode and the mouse remains frozen. The picture is this: The windows opens, a warning appears that a register was recovered from the log, and the cursor remains frozen. Would anyone please tell me what should I do. I have one Hiren's boot CD but I dont know what to do with it. If any of you guys need more information I will provide right away. THnx This can be caused by many THINGS. Could be RAM, Hard Drive is ill for swap file access, or main board related. I would remove and reseat the RAM, make sure the CPU is not clogged with lint and dust, and download and burn memtest86 to a bootable CD or DVD and run 3 or 4 passes of memtest86 on this system to make sure that the memory is good.

I would boot the system off of a Live Linux distro like Linux Mint or Ubuntu and make sure that it behaves when running off this live environment. From this live Linux environment both distros have good Hard Drive tests that can read the SMART data and runtime of the hard drive and give you information as to if the hard drive is really healthy or not. You can also run tests from this environment on the hard drive using the built in utility that is accessible through the GUI under system tools.Thank you for the answer Dave. I removed and reseat RAM, cleaned CPU and checked hdd for errors.
I am sorry for my question I am not a professional just to be sure: Are you proposing that the fault is in hardware ( just in order to avoid reinstalling windows)?Generally issues like the ones you are having can be caused by many things. The best thing to do would be to try to isolate where the problem is located. It could be memory, main board, hard drive, or weak power supply, as well as can be DEVICE conflicts if this system has had hardware added that is not part of the original build, although this is a very rare occurance these days with plug n play.

A long time ago I had a customer CONTACT me with an issue with installing Windows and it installed FINE, but it would always crash in one spot on boot. The problem was as simple as the fact that the original Windows Installation disc was scratched up and not well kept so this portion of the disc was corrupt and that corruption made its way to the Hard Drive installation without any errors on install. The fix here was to borrow someone elses Windows 98 Disc and use their own key with the other persons disc. Is your disc free of scratches?

I'd run memtest86 to test RAM for 3 or 4 passes. If that is fine with no errors shown, then I'd test the hard drive with a Live Linux distro such as Mint 14 or 15 or Ubuntu, in which you boot the system off of the DVD, but do not need to install it, and observe how the system behaves in this different environment which should operate flawlessly as long as you have at least 1GB RAM and a Pentium 4 or better CPU. If it acts up during this Live Linux test and it meets the system requirements of 1GB RAM and Pentium 4 or faster CPU and it passed the memory tests, then it is likely a weak power supply or main board issue as for this Live Linux distro operates without the need of a hard drive and without the need for an installation.

To help you better what is the system make/model and specs? CPU, Amount of Memory, size of hard drive etc...Here's a good harddrive diagnostic program.

Run hard drive diagnostics: tacktech.com
Make sure, you select tool, which is appropriate for the brand of your hard drive.
Depending on the program, it'll create bootable floppy, or bootable CD.
If downloaded file is of .iso type, use ImgBurn: imgburn to burn .iso file to a CD (select "Write image file to disc" option), and make the CD bootable.
For Toshiba hard drives, see here:
