The old PC from 2002 starts up, yet the screen remains blank.
I retrieved my old PC from the attic, purchased by my parents in 2002, along with a Samsung monitor. I cleaned both the inside and outside of the PC and attempted to start it. The PC boots up but doesn’t show anything on the screen. On the front panel, the HDD light is red, which I suspect could be the main issue. The monitor functions properly when connected to an old notebook from 2007 with a VGA port. Dust inside the PC was removed using compressed air; all components appear intact, though I’m not an expert and can’t confirm everything. I also couldn’t locate a keyboard or mouse, but it seems unnecessary for basic operation. I’m unsure if a working HDD is required for the BIOS to display, as I expected something but found nothing visible. The monitor works, so the problem might not be with the HDD itself. Could you assist? What checks should I perform to verify the HDD’s condition and determine whether repair or replacement is needed?
Welcome to the forums, newcomer! I retrieved my old PC from the attic, purchased by my parents in 2002, along with a Samsung monitor. When sharing a troubleshooting thread, it's important to provide detailed system specifications. Please list your build details as follows:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
Include the age of the PSU, not just its make and model.
Moved the thread from the Storage section to the Systems section.
You can add to what Lutfij asked for. There are many pictures available, including the motherboard, front and back of the case, a photo of the power supply, and the label on the hard drive. There could be additional details you're not seeing that we might have missed. Also, if this was a prebuilt product from companies like Dell, HP, Gateway, and the model name, please share the images on imgur.com and then link here.
old capacitors on outdated graphics cards may dry out or expand, causing the circuit to receive incorrect voltage and fail to operate properly. these components are typically reliable for at least five years. in older systems, replacing them is straightforward if you can locate a compatible new card. it’s simple—remove the old ones and install new ones. inspect certain capacitors for swelling or leakage of brown fluid, which indicates failure. some monitors may require manual mode adjustments to interpret non-standard video formats.
I seem to remember an option in some old BIOS marked "ignore keyboard error on startup" meaning the computer would continue the boot process, even if it failed to detect a keyboard. If this option isn't set, the computer will stop and wait until you connect a keyboard. If the GPU and screen are working, you'll usually see a message saying "keyboard missing". Even without a mouse or keyboard, I'd expect the screen to light up with POST messages.
Personally, I'd plug in a PS/2 keyboard and PS/2 mouse to give the BIOS a fighting chance of booting up from hard disk. If you don't have either of these items, search the second hand markets, eBay, or ask your local computer repair shop, if you have one nearby. If it's a really old computer (from the 1980s) it might have a 5-pin DIN keyboard plug and not a more "modern" 6-pin min-DIN PS/2 plug.
The photo below shows PS/2 mouse and keyboard sockets on a typical older motherboard. Note the colour coding.
Equally likely are swollen or burst electrolytics on the motherboard, especially around the VRMs (Voltage Regulator Modules). I've re-capped a number of old boards. A delicate process if you don't want to drag the plated through hole out with the capacitor leg.
I normally replace all capacitors of exactly the same size/value, when at least one of them has failed. It can take more than a hour of careful work with the correct tools and technique. Practice on an spare board before tackling a prized motherboard. It's easy to damage the PCB tracks.
In the photo below, the brown "goo" is the electrolyte which has leaked through the burst tops of the capacitors.
If you have a GPU with bad caps, it's easier temporarily to swap it for a graphics card with good caps, to see if you can get the PC up and running.
Take out all the discs and disks, swap the BIOS chip, and run a test.
Sorry for the delayed response. Over the recent weeks I've been swapping out different components of my PC, yet the problem persists. I still face the situation where I turn on my computer and it starts up, but no output appears on the screen. Here are the photos you provided:

My current specifications are:
CPU: Intel Pentium 4 SL6DV 2.4GHz
CPU cooler: Intel C33218-003
Motherboard: ECS P4VXASD2+ REV 5.0 (478 socket)
RAM: Nanya 128MB DDR-266MHz CL2
HDD: Western Digital WD400BB 40 GB PATA 3.5''
GPU: 3G Graphic Nvidia GeForce 2 MX 400 64MB AGP
PSU: BanditPower HX-380 400W
Chassis: unknown
OS: None installed; I have WinXP on another HDD
Monitor: Samsung Samtron 76E
Following your guidance, I inspected my old motherboard and noticed some capacitors with bulging tops. I replaced the motherboard, but the issue remained. I then purchased replacement parts for everything except RAM and the chassis. I replaced the CPU, cooler, HDD, graphics card, and PSU, yet the problem continued. Believing it might be the monitor, I connected a VGA-to-HDMI cable and used an HDMI display. Again, the same issue occurred. The PC powers on, but nothing appears on the screen. I returned to my CRT monitor.
Currently, no operating system is installed on the HDD, which shouldn’t be the reason. Ideally, the PC should boot into BIOS and display something on the screen.
I attempted to replace the CMOS battery twice, but it didn’t resolve the matter. I also confirmed that a PS/2 keyboard and mouse are connected.
Regarding RAM, I experimented with various modules in different slots, but nothing resolved the problem.
In summary, I essentially have a brand-new PC (most components replaced) that powers on, the CPU cooler is active, and everything appears to be functioning, yet the screen remains blank.
