Power Supply Question?

Posted on July 13, 2010 by admin| 4 Comments

I have a PC that was left on, when I came home it was off. It would not restart. It would POST and then return a HDD not found error. The primary HDD is not recognized even in the BIOS. Last night I used a Linux live CD to boot and check the secondary HDDs data.
Today I tried to boot from HDD, CD, and floppy, nothing works, but it still POSTs, and I can change things in the BIOS. I have this > http://www.newegg.com/Product/Product.aspx?Item=N82E16899705002 < PSU tester and when I test the PSU the -5v fails to test.

Is the PSU the problem or is there another issue that could be causing the?

Old Pentium 2 Monitor Black (Video Card Problem)?

Posted on July 11, 2010 by admin| 4 Comments

I work as a part-time computer technician assistant for allinonecomputer and I had a customer bring her computer to my house, and due to me being limited in parts, I tested her Power Supply on my brother’s motherboard, turns out the power supply was bad because it fried two motherboards.

So I had to replace his HP intel motherboard with his celeron 2.7ghz processor with a pentium 2 266mhz processor. Problem is… the damn thing boots up, but the monitor remains black. It has one agp slot and about five pci slots, and one ISA slot.

I have four 4-16mb video cards I tried using in every single slot, repeatedly booting it up and shutting it down and switching. But every slot and card I try… nothing works.

I tried booting a linux live CD, but for some reason (that I can’t see) it’s not booting at all. I also tried a windows CD, but I couldn’t see what was going on.

Any suggestions?

(I’ve gotten most of my computer experience from modifying programs and frankensteining computers in my basement, so I have a lot of non-professional computer background. )
