need a little help here.
last night my pc was functioning perfectly however i accidentally shut off the pc while windows was updating the pc during shutdown.
Today morning when i tried to boot, it failed.
After switching on the PC, all the fans start running but after a single beep, the green light glows continuously and then after sometime simply shuts down and then reboots but then again the same thing happens. This is occuring continuously. I have observed the following things:

1. The display starts up then goes off saying 'no signal'
2. During boot, the red HDD light blinks once and then doesnt glow even once after that
3. Nothing appears on the screen but the PC keeps trying to reboot itself after 30 secs approx.
4. I am unable to see a POST screen or access the BIOS
5. When i touched the HDD, it felt quite warm but dint feel like it was spinning
6. 4 POST lights on the MoBo light up but nothing happens after that.

I have tried the following things:

1. Tried Hard reboot (failed)
2. Opened and reseated the HDD wiring and cables, the graphics card, and alternated between the RAM modules (failed)
3. Pulled out the CMOS battery and then Reset it. (failed)

Even after all these attempts the same sequence occurs.
Please someone help me as i have my project files on my PC and i am unable to work as my laptop is out for repair as well
If possibe i would be happy to add a video

System restore from safe mode to a time before updates?

Do as area51 said, most likely it's just your windows install gone bad.

If you can't see the POST screen, then it maybe outside of windows. Try unplugging the hard drive you boot from, and then boot. If you see a post screen and then the BIOS complaining that it can't find a boot drive, try plugging back the drive, and see if you can or not see the POST screen.

if you can get to a POST screen you can reinstall windows. if you do not have POST then you will probably need to replace your motherboard.

Click F8 at startup, and from the list of startup selections, select Safe Mode by using the arrow then hit enter.
Use System Restore once there, to pick a Restore Point before your problem..

The OP apparently can not see the POST screen and can't access the BIOS menu.

thank you for all your replies...

exactly as maxx power said, i cant even get to the POST screen. there is absolutely nothing on my screen. The monitor only has an amber light glowing at the bottom as it does in standby. All the PC and case fans spin up and 4 small lights on the top right corner of my mobo light up. i think its supposed to do that but then nothing happens, the pc just tries to reboot automatically but it loops back to the same point over and over again. again i want to point out that i do not feel the HDD is spinning but it does get pretty warm after a few seconds and the 'red' light that supposed to blink to indicate HDD usage does not do so (only a constant green light can be seen on the front panel of my PC case)

i will try to remove my HDD and try again

any other possible solutions, i really donw want to RMA my mobo unless i am certain that there is something wrong with it

My PC specs:
CPU : INTEL CORE i5 750 2.66 Ghz
MoBo : GIGABYTE H55m USB3 (V1.0)
RAM : CORSAIR 4x2 GB 1333 Mhz
HDD : WD CAVIAR BLUE 500 GB
GFX : GALAXY GTX 460 OC
DISPLAY : VIEWSONIC VA926 (19")
DVD DRIVE : SONY DRU 820A
OTHER PERIPHERALS : LOGITECH WIRELESS KB+MOUSE COMBO (MK 320)

Do you have another videocard handy ? Try swapping the video card you have with another one. Try booting with only the Board+Ram+CPU+Video Card (of course PSU), all other installed devices are unplugged (both power and signal).

If you have tried swapping the Video card and the above, and this still occurs, you MAY have to RMA your board.

I don't think your CPU has a built-in graphics portion. See:

http://ark.intel.com/products/42915/Intel-Core-i5-750-P...

Even an old PCI video card will work if your MOBO has PCI slots as well in addition to PCI-E. Or borrow one from a friend ?

Well, you want LGA 1156, not LGA 1155. The 1155 is for the current generation COre i-something_or_other.

Try to see if online retailers still have any 1156 boards around, most should be gone by now. I think if you absolutely have to stick to your current CPU, you can't be choosey, because it is an old platform now, and no one is expected to stock motherboards.

Try www.ncix.com
www.directcanada.com (related company)
and if you are in Canada, try www.canadacomputers.com
and
www.tigerdirect.com

If you can't find something suitable, my suggestion would be to sell the CPU and upgrade, you can recycle your old RAM, HDD, Case, etc.....
