Although an old question (I'm new here) I had a problem like this come into our shop about 6 months ago.

It was not a malware/virus etc problem. Wasn't a PSU issue either. And the motherboard tested fine using a P.O.S.T. card and booting from an offline OS.

Add to that it would only go through repeated reboot after the unit had been running a while (10-20 minutes). Then the nightmare would occur.

Letting it sit a few hours it would start up fine and stay running for a while. (see above)

Turned out (after much head scratching) it was the power button on the front of the unit. The contacts were wore out. Once the unit warmed up it would cause the contacts to separate enough to cut power. Then in a matter of seconds they would cool enough to power back on. A few second later the boot/reboot fiasco would start all over again.

What I learned in the process was never overlook the most simple of things while assuming it may be something complex.

Replaced the switch (cost me $.49) and the customer was more than delighted to dish out $40 for the repair.

The first thing I would check for are viruses. Use AVG's rescue disk to scan it for viruses.

Try accessing safe mode with networking (tap f8 as soon as you power it up) and download Malwarebytes, which can be downloaded via www.download.com If your issue is related to a virus, this small easy to use application will get rid of it. If this application yields to zero infections, then it could be hardware related, and we will require more information on how it happens. Good luck

You can try repairing your windows by using your operating system disk or if problem still persist then you may need to go for a clean install. In case if you dont have the CD then you can install it by following steps:

Step 1- Download ISO image of Windows from: windows.microsoft.com/ website

Step 2: Download YUMI from: www.pendrivelinux.com/yumi-multiboot-usb-creator/ website?

Step 3- Plug in your USB in pc.

Step 4: Run YUMI and follow the on-screen instructions by selecting the appropriate operating system.

Step 5: Give path of the ISO Image and select the USB drive to make boot-able disc

Step 6- Plug in the USB onto the system on which you need to install the windows.

Step 7- Turn on the system.(Change the boot preferences to USB if the system do not automatically start booting from USB).

Step 8- follow the on screen instructions to complete the windows installation. Thanks
