No display when trying to boot up

My troubles started yesterday when I tried to power on my computer nothing was appearing on the screen. After several times to boot up the display finally appeared. The same thing happened today. I don't know if it's my monitor, video card, or the monitor's cable. Any ideas on what's most likely the cause?

It does not have onboard video. When the the display would not come on the hard drive light remained on for like 10 mins until I rebooted. -

Optionsrwwest7 Member Posts: 300Very rarely do video cards go bad, it sounds more likely to be a motherboard issue. Do the CPU fan, Power Supply fan and hard drive all spin up? If so then you can likely rule out the power supply also. If I were you I'd disconnect the power cable, remove the battery, remove the RAM, wait 10 seconds then put everything back to together and try again.

I opened the case and noticed bulging or leaking capacitors all near the AGP slot. We've got about 30 or so Dell GX270's and all the boards were replaced except that one because the tech said that service tag # wasn't affected by the recall.

I do have a few bulging capacitors next to the CPU but they have been like that for years and I have had no problems, but who knows they might be causing a problem now. I doubt I could get a replacement as it's and old VIA P4PB 400 board. -
Optionsexampasser Member Posts: 718 ■■■□□□□□□□I may have found the potential cause of my problem, recently I attached a WD external hard drive to the system. Today I tried to boot up and the display would not come on, I decided to disconnect the external hard drive and upon the second try the display appeared and it booted. It may have just been a coincidence though.

Optionsrwwest7 Member Posts: 300I had something similar happen to me a few years ago. You may just be over stressing the power supply with the added hard drive. For me upgrading to a higher wattage power supply worked.

Optionsexampasser Member Posts: 718 ■■■□□□□□□□The bulging tops generally mean they're failed or failing. They don't always go pop however and may just operate in a degraded state. This means that the ESR or capacitance goes off from the rated value and the voltage regulation for the CPU or other motherboard components is no longer as stable. If you're lucky then it still continues to work at least until the capacitors degrade further. If you're unlucky then they explode with a bang and a nasty smell.
So I pretty much have a motherboard on its last legs. At least it gives me an excuse to go out and buy/build a quad core system to use with VWware, its amazing that my old tower has lasted so long considering that I'm overclocking it to get to 2.7Ghz. -
