The symptoms described by — front-panel LED flashing, keyboard LEDs cycling and the speakers “pulsing” immediately after power was restored — point to a hardware POST failure rather than an operating-system issue. Common causes are power-delivery or board-level faults (a failing PSU, a short from front-panel wiring, or a damaged motherboard component), though bad memory or a loose card can produce similar signs.

As noted, POST/beep details and the motherboard model are the key pieces of data for decoding what’s happening; as suggested, memory is a plausible area to check but it should be tested alongside PSU and board checks rather than assumed to be the sole cause.

A compact, ordered diagnostic approach that adds to the thread replies: first, kill mains and inspect the board for bulging or leaking capacitors, scorch marks or loose power connectors. Remove nonessential devices (drives, add-in cards, USB devices) and attempt a minimal boot with only the CPU, CPU fan, one memory module and video hardware if required. Test memory modules one at a time in different slots to separate a bad stick from a bad slot. Bypassing the case power switch by briefly shorting the two power-header pins will rule out a faulty front-panel switch or wiring (only for someone comfortable with live testing).

If the board still won’t POST, verify PSU rail voltages with a multimeter or a PSU tester; unstable or low +12V/+5V/+3.3V rails point to the PSU. Clearing CMOS (remove the coin cell briefly) can help if firmware is stuck. When bench equipment or spare parts aren’t available, the most common failing parts are the PSU or the motherboard; a repair shop can bench-test with known-good components. Always disconnect mains power before touching hardware and use basic ESD precautions.

Settle down and be more specific, man.
How many beeps (I figure that's what you said by "pulsating"), (short, long) and wich motherboard do you have.

open the case up and pull out the ram sticks. blow some air in the slots you pulled the ram out of and put the ram back in and make sure they are firmly clicked down on both sides. turn it back on and see if it works.
