OK ,first of all this is a home built system-

Mobo-Abit IC7-Max3
CPU - Intel 3.4 GHZ with Cooler Master Vortex TX. CPU Fan for AMD/INTEL
Western Digital / Caviar SE 16 / 250GB / 7200 / 16MB / SATA-300 / OEM / Hard Drive
RAM- Patriot PDC1G3700ELK - 1GB PC 3700 (3-4-4-8)
ATI Radeon 1600X Pro graphics card
OCZ 600 watt PSU

Now for the problem- I just finished playing UT 2K4, exited to the desktop. I went for a cig. When I came back ten minutes later the monitor was blank. I have it set to turn off after 4 hours not ten minutes.
This is what I did so far thanks to a friends check list---
recheck all the connections to your equipment....uplug- then re-plug that stuff in.[molex]..paying attention to the connections. If your running a pata hd...get another "know good" ata cable to use....if you have a multi meter, turn power on and check the power to at each molex connection used for "necessary" equipment. 10% is the limit for droop.....3.3volt/5 volt/12volt are the possible currents from the power supply. you wont be able to check the mobo connection unless you jumper the p.s.///you will need the literature from the p.s. to know which to jumper. without jumper set up...you cant check the molex connections without it attached to your mobo....either way, eliminate your first thing...ps...it could be a load problem too, but lets just start with if it is giving power to your important molex connections.

jumper= find the two orange wires on the end of the "ps mobo connector"...on the side with the locking tab.....including the first slot..jumper the two that are 3-4 on that side[should be black and green wires]....it should turn on then...fan will spin...then check your voltages at the various molex's.
I get one beep 1 second long when the graphics card is out.The light on the mobo is green when the computer is off and red the second I turn it on.
The battery tested 3.079 V. All the voltages checked out on the power supply.

welcome to PCHF wfelter2000,


when you came back to your PC was the system or was the monitor just off? also when you boot up does your system go through POST? or does it not turn on at all?

When I came back the fans and lights were still on the tower. I thought the monitor shut off. I tried clicking the mouse, moving the mouse, hitting enter but nothing worked. Then I tried to re-boot. No post! No BEEP! Lights and fans came on, HD felt like it was running but that's it.I may take it down and bring it to a friend who repairs them cause it's my gaming machine and I miss it terribly!

thanks for your info.

So we have no Beeps when your machine is turned on. this sounds like one of two problems. either you're Power supply is failing or there is a problem with you're system board. the way i usually test this is with a 2nd power supply. if the 2nd power supply brings up the machine then there you go. 90% of the time it will be your PS.

I have a friend, who repairs puters, checking it out . I've tried everything I can do. Thanks for the replies. I'll get back to you's with the results.
