Key clue from — a speaker beep appears when memory is removed — narrows the problem. That tells you the speaker and basic power are present, so the failure happens in the early init sequence that runs once RAM is present (BIOS/CPU/memory init or video hand-off), rather than a dead speaker or totally dead motherboard. That changes which tests are most useful.

First practical checks (safe, low-risk): clear CMOS (power down, unplug, remove coin cell or use the clear-jumper per the manual, discharge caps by holding the power button), then try one known-good DIMM in one slot only. Inspect the 24-pin and the 4/8‑pin CPU power plugs for loose pins and any burn marks before powering up. Use short, controlled bursts of canned air to remove dust from sockets and fans, taking ESD precautions and holding fans still to avoid overspinning.

Graphics and display diagnostics (builds on and ): confirm the graphics card receives its PCIe power and that its fan(s) spin on power-up. If the board has onboard video, switch to that output in the BIOS/CPU arrangement or physically reseat the card and retest with a different video input on the monitor. A simple phone camera pointed at the screen can reveal a faint POST or text that the eye misses. Don’t flash BIOS unless you can research a matching BIOS file for the exact board and have a stable power source.

If those steps fail, inspect the motherboard for bulging/leaking capacitors, scorch marks, or swollen components and consider testing with a known-good PSU or a POST debug card. If uncertainty remains after these checks, record exact motherboard and CPU models and seek bench testing at a repair shop — avoid forceful component swaps that could void warranties.

What ive tried so far is to boot with ram out i get beep then. I put it back in and took off mouse and keyboard, tried new monitor still same problem, the blue on off light on monitor just flashes with nothing on monitor

might be your monitor cable is damaged. might be your motherboard is damaged. it can be so many problems. sometime a hardware creates problems and does not allow the oc to boot. try removing some hardware like cd rom, hard drive, ram etc and then boot. you will find the problematic hardware then.

try replacing the vga card and see what happens

Basic questions. Did it work? when did stop it working? Did you add anything or take anything out of the system? Try the 'strip to a basic system' PSU, M/board, memory,and monitor connected only. If you can't get a display then does the system have an onboard video controller if yes try removing the VGA card and use the OBoard VGA. IF no then beg, borrow, another VGA controller card (as close to what you had) and try that. If you can't do that then buy a another VGA controller (very tempting to do and upgrade whilst your at it, but not a good idea!) second hand is OK if you can get it tested, and or get the original one tested is better.

It is an issue of your RAM and Dust. Try to re-connect your RAM after clean it.

Its a ram problem i hope. Just try this soln also. It helped me a lot.

try to boot the system using a cd drive which consists of os cd.

If the screen shows the installation procedure, you are safe and now you can cancel installation and reboot your system.

else

the problem is with your moniter cable[Soln: try other cable]

else

the problem is with your motherboard.

Hope this helps.

Have a happy time
