my pc still restarts after windows loading screen. these are what i already did.

1.) formatted hdd (tried to use it on another cpu and works fine)
2) changed the ram

but still it reboots itself. when i disable automaticrestart on system failure it just gives this technical information

0x00000007B (0xf7970524,00000034, 0x00000000,0x0000000)

Given 's tests — HDD freshly formatted and confirmed working in another machine, RAM swapped, and Safe Mode still rebooting as suggested — the STOP code 0x0000007B most commonly means INACCESSIBLE_BOOT_DEVICE. That points first at a storage-controller / BIOS boot-mode mismatch or boot-record/BCD corruption rather than CPU overheating. 's thermal advice fits hard shutdowns, but a blue screen with 0x7B usually implicates the boot path or drivers, not thermal throttling.

Prioritized checklist (fastest isolation first):

  • Confirm which Windows edition is installed (XP vs Vista/7/8/10) since repair steps differ.
  • Verify motherboard SATA mode (IDE/Legacy vs AHCI vs RAID). A change from the mode Windows was installed under will produce 0x7B. If XP was installed and the board is in AHCI-only mode, try switching to compatibility/IDE or install the correct storage driver.
  • Swap the SATA cable and use a different SATA port (prefer the controller's first port). Disconnect any extra drives to remove multiboot/drive-order variables.
  • If Safe Mode fails, suspect missing storage driver or corrupted boot records — move to offline repair.

Useful recovery commands (backup or image before running any destructive repair):

For Windows XP Recovery Console:

fixmbr
fixboot
chkdsk /r
bootcfg /rebuild

For Vista / 7 / 8 / 10 WinRE:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
chkdsk /r

If those fail, run MemTest86 for RAM, check SMART from another system or a live USB to confirm disk health, and consider an offline rescue scanner for MBR/rootkit infections. If the drive boots fine elsewhere (as noted by ) and all software fixes fail, the motherboard SATA controller or its firmware may be faulty; try a known-good controller or a different motherboard for final isolation. Take an image or backup before running MBR/BCD fixes, as those can disrupt multiboot setups.

Have you tried starting Windows in safe mode?

there may be problem with your motherboard

if your blue screen isnt random
i.e it occurs in a fixed interval of time (then there may be problem of ram)

Well, there could be a reason of your processor overheating. Do this: remove the processor fan (if you have a stock fan) and check whether the thermal compound completely covers the interface between the fan and the processor. If it does not do, then remove the paste and apply it again. And then reinstall your processor. Once my pentium 4 processor shot upto 90 degrees celcius and I had to do that. After I made sure everything fits correctly it went back to 40 - 50 degrees...
