hi, i was given a emachines T1742 desktop pc it did not have a power button cap to turn it on so i had to bypass the original with ANOTHER on the motherboard and got it to turn on that way but i could not get a signal to the monitor so to RULE out that the video problem was from the monitor i connected it to a different pc and it worked just fine, i also noticed that all of the wires from the power supply looked very old, the casing on them is hard also for whatever reason somebody cut out one of the molex conections, i also found four wires that go to the floppy drive those were cut and hand twisted and taped with regular household tape, it looked very unsafe. when i first turned on the pc i also noticed that the hdd light came on then turned off and the fan was working ok, the only information that i have right now about this pc is what i have seen but i cannot ACCESS anything due to the video issue, but i took note of all the information on the stickers and they are as follows: EMACHINES T1742, MICROSOFT WIN XP HOMEEDITION PREINSTALLED, MAT NO. 133517, CD ROM 101/100 MBPS ETHERNET FOR CONNECTIVITY TO BROADBAND CABLE/ DSL, 1.70 GHZ INTEL CELERON PROCESSOR, HEADPHONE, MICROPHONE, CD ROM 4X MAX.READ, 40GB HDD ULTRA DMA, 3D GRAPHICS INTEL EXTREME GRAPHICS AGP, 56K FAX MODEM V.92 READYPCI MAXIMUM DATA TRANFER MAY VARY AND ARE LIMITED TO 53 KBS, 128 MB DDR, 6 USB PORTS 2 IN THE FRONT AND FOUR IN THE REAR, S/N: QIP2A 101 02464, PART NO. 511725. i have made sure that all the wires are no longer exposed and bare, i also took out the hdd so that i can test it out with an external adapter. i hope someone can help me out with the video signal so that i can actually get to see what this machine's physical state is. thanking you in advance.Replace the PSU...hi patio, and thank you for your reply. i am going to replace the psu, now the psu that is currently installed is 350w, when i install the new one, do you think this will help me with the video issue?, thanks again.I can;t guarantee anything...but a flakey Psu can cause all sorts of issues...
If in fact it's a problem with the video that can also be ADDRESSED...but a chopped up PSU needed replaced either way...
Who knows what they were attempting.
