Computer ran fine for a while.


A few months ago, it started to restart on its own (not windows restart, but hard reset)


Now it doesnt even get to the boot screen. The LEDs light up for a split second and I hear the fan start spinning, but then it just shuts off again. It just does this cycle until I switch off on PSU.


No idea whats wrong, can't even diagnose. No spare parts.


Any ideas?

Sounds like your power supply is going bad.

having you tried checking your memory stick, sometimes all you have to do is pull the memory ,wipe with a pencil eraser on golden fingers, clean the pci slot, were there any beeps on start-up? if so how many? Depending on the number of beeps each one has a different answer. Like one beep only usually

When you turn the computer on, it performs Power On System Test (POST), during which it checks and initializes the system's internal components.
If a serious error occurs, the computer does not display a message but emits a series of long and short beeps instead.
Beeps are your computer's way of letting you know what's going on when the video signal is not working.
These codes are built in to the BIOS of the PC.
There is no official standard for these codes due to the many brands of BIOS that are out there.

To decode the meaning of your computer POST beep codes you must consult the manual of your motherboard.
If you don't have a motherboard manual or if it's incomplete you must search on the site of your computer manufacturer.




1 The memory refresh circuitry has failed
2 Parity errors have been detected in the first 64 KB of memory
3 A failure has occurred within the first 64 KB or memory
4 System Timer failure: Timer 1 on the mainboard does not work properly
5 The CPU has generated an undetectable error
6 8042 Gate-A20 failure: BIOS cannot switch the CPU into protected mode
7 The CPU has generated an exception error
8 The video adapter is missing, or the memory on the adapter has generated a failure
9 The ROM checksum value does not match the value in BIOS
10 The shutdown register for CMOS interrupt channel 2 has failed POST; the system board cannot retrieve CMOS contents during POST
11 Level-2 cache memory has failed the tests, and has been disabled
2 short POST has failed, caused by a failure of one of the hardware tests
1 long, 2 short Failure in video system: a checksum error was encountered in video BIOS ROM, or a horizontal retrace failure has been encountered
1 long, 3 short Failure in video system: the video DAC, the monitor detection procedure or the video RAM has failed
1 long POST procedures have passed
