Short checklist that moves from quick/low-risk checks to deeper diagnostics (ties to ideas from , and but goes further).

First, isolate hardware: remove all USB devices, SD cards and any docking peripherals. If the battery is removable, try booting on AC only and then with battery only. Listen for BIOS beeps at power-on (check the laptop maker’s support page for what the pattern means). Reseat the RAM modules and try one stick at a time in each slot — bad RAM often causes immediate reboots before Windows loads.

If hardware still looks suspect, run a memory test from bootable media. A reliable tool is Memtest86/86+ — burn it to a USB stick or CD and let it run several passes; even a single error usually points to faulty RAM rather than Windows. See Memtest86+.

To check the disk without booting Windows, boot a Linux live USB (for example an Ubuntu live image) and inspect the drive there. From the live session use SMART utilities to see drive health and run short/long self-tests; smartmontools provides that functionality. Example reads and self-tests are done with smartctl from the live environment. See smartmontools and Ubuntu downloads for creating rescue media.

If hardware passes, focus on Windows repair: from a Windows XP install CD or recovery media run Recovery Console commands such as chkdsk /r (and, with caution, fixboot/fixmbr) to repair filesystem or boot records. If you can get into a diagnostic Windows session, run sfc /scannow and use System Restore to roll back recent changes. Back up the drive first (remove it and connect to another PC with a USB adapter) before doing risky fixes.

If the machine reboots even with the HDD removed or shows no POST, suspect motherboard/CPU/VRM faults and consider professional repair. The above sequence will tell whether to focus on RAM, disk, or deeper hardware work.

see if you can get a command prompt using a bootable floppy?

see if you can get into windows using safe mode.

Alright, See if you can boot into safemode.
If you cant, when you press f8 there should be an option to disable automatic restart, I dont remember the exact name. When you then try to boot it should give you a blue screen with an error code. Write down the error code and file name and google it to find out the error. You might have to manually delete the file causing the problem, or find a copy to overwrite with.
