I would like to start off by saying i have built a few computers and i know how to put parts together ans such. However this has stumped me. A friend of mine was having a get together and we were gonna play some games he told me to bring my computer he lives just a house away so i carried it over set it down plugged it in and turned it on, well attempted to. The computer turned on but no screen appeared on the monitor just a black screen blank. There was no loading screen it didnt even boot. My first thought was the monitor because it was fairly old so i plugged it into my friends and same screen appeared. So now i was getting worried, my second thought was my video card. This was maybe a month old, i just bought a new one and i was thinking something went wrong with it, so i brought my computer home and put in my older video card and the same thing happened. I then took everything out of the computer and put in the basics, motherboard, one stick of ram, cpu, power supply, and hard drive. This happened about two months ago and ince i have pretty much given up hope but recently i stumbled upon it again and i would love to get this computer going again. Any help would be greatly appreciated.
Windows 7 is currently installed on my computer
here are the parts that i have currently installed
-MOBO-GIGABYTE GA-K8N Ultra SLI
-CPU-AMD ATHLON 64 the number reads ADA3500DIK4BI
-HARDRIVE-Quantum Fireball QML20000LOA lct 15 series
-PSU-Mapower PX400C which seems ancient since i cant find a google search on it. Its got a 400 watt output
Yesterday i tried turning it on just for the heck of it and it turned on for about 5 seconds then it shuts off, i was thinking then it would be the power supply so i tried 3 different supplies all to the same effect except some of them turned off in a shorter time period. I tried a different hard drive, different RAM different Video Card i even tried it on an older mobo with no luck. On one occasion with a different mobo it stayed on however nothing showed up again on the monitor. Here are other parts i have that i can try
-MOBOS-GIGABYTE GA-7VKMP the CPU that goes along with this is an AMD ATHLON 64 AXMJ2800M and is a socket 452
-MOBO #2-GIGABYTE GA-K8VM800M the CPU with it is AMD ATHLON 64 ADA3000AEP4AX socket 752
-RAM-Gskill F1-3200PHU1 and DRAMMASTER pc2100 DRR266 (x2) and BRAVO 512mb DDR DIMM PO123001
-VIDCARDS-RADEON VisionTek X1300XGE and GIGABYTE GV-NX66T128D and nVIDIA Geforce2
-HARDRIVES-40G AT MAXTOR D740X-GL 3.5" series and DIAMONDMAX VL MAXTOR 32049H2
I also have two other PSU and four other CDROMS
Also something to note is when i looked at my CPU up close i saw one of the pins is broken clear off, although it has been like that before i took it out could that be effecting it?
I think i have narrowed it down to the mobo or the CPU but any advice or help like a said would be greatly appreciated!
