I wanna first thank to all DANI web members, Administrator, moderators and to all it's members.

I have a PC, which is Windows XP home Edition. It doesn't boot when i start, this is what happens when i start the PC.
After a few seconds of the start, i am getting blue Monitor with the Message <NO SIGNAL>. And it is still the same result, if go on the SAVE MODE, WINDOWS NORMAL STARTING, NETWORK MODE . There is no change in all MODES. After the first start, let me say after some secods the NO SIGNAL messages appears and it will restart austomatically: and it is like loop, restarting again and again when ever <no signal> message appears and doing the same again.

This Message is on the head. Your windows couldn't be shut down normall because of Hardware or Software Problems
A friend told me, it could have Graphic or video card error, the resolution on the monitor is not ok too.
So Please i need Help.
i really don't know what to do

Brief recap and a focused, safe troubleshooting path (builds on suggestions from , , , and ). “No signal” a few seconds after power-up that then forces an automatic reboot usually points to hardware, but you can narrow the culprit fast by watching what the machine actually does and running a short, ordered checklist.

  • Quick external checks: try the monitor and cable on another computer and try a different cable/input (VGA/DVI/HDMI). Make sure the monitor’s input selector matches the cable in use.
  • Watch power-on behaviour: note whether fans spin, whether HDD/LED activity appears, whether the BIOS splash shows, and whether the board emits any POST beep pattern. No fans or lights → suspect PSU; fans but no video and no beeps → GPU or motherboard.
  • Minimal-configuration POST test (systematic isolation): with power off, remove nonessential peripherals (optical/HDD/extra cards). Leave CPU, one RAM stick, PSU, motherboard and video (use onboard if available). Try each RAM stick in each slot. If the system shows video now, add components back one at a time to find the failing part.
  • GPU checks: verify any 6/8‑pin PCIe power plugs are seated; confirm the GPU fan turns on; if possible test the card in another PC or test a known-good card in this machine.
  • PSU and voltage checks: if you can, swap in a known-good PSU or use a PSU tester/multimeter (only if comfortable). Intermittent shutdowns or reboots under no-load often point to PSU protection kicking in.
  • Firmware and board-level steps: clear CMOS (remove battery/jumper), check BIOS video priority (PCIe vs onboard), inspect the board for bulging capacitors, burn marks or loose standoffs.

Do not work inside the case while it's plugged in and take ESD precautions. If these steps don’t isolate the fault, a local shop can quickly bench-test the PSU, GPU and motherboard. If you can report what you see on power-up (fans, lights, BIOS splash, beep codes) that will make narrowing the next step much faster.

Are you saying that you get a Blue Screen of Death that states no signal, or the regular monitor "no signal" screen?

Hi Mubo

The first thing i would do is remove all the PCI cards from the machine ... including your graphics card. Hopefully your motherboard has a VGA port.... plug you screen into this port for know... then try to boot PC. If the screen works ... then you may have something pulling the PCI BUS down. If computer boots up fine good ... shut it down. Install the graphics card and try again... if you get the same error ...first look at your Power supply... swop it or replace it... it may not be providing enough power... let us know up to this pont

Kindest regards
Darren

I mean regular monitor "no signal", which appears a few seconds of booting, is booting failure and doesnt work even with save mood option at very start of booting.

thanks for reply

Looks like your sys has been pretty well booted if you are getting the choice of which level of OS to load [Safe, Normal etc...].If you select Safe mode do you see a list of drivers loading [they scroll rapidly in B&W on your screen]?

graphic card or monitor's cable.

Its very well a hardware issue and not a software issue...could be even solved just by tightening some wires. Check if the monitor cable connecting the CPU is properly fit in.
