Plug off the Monotor Data cable from CPU and power the Monitor. If anything display like no signal or in old monitors, Bright/Contrast/Color switch light up display, Then monitor OK But CPU Defective. If monitor not power up even LED not glowing, Monitor power supply unit problem.

If CPU Problem, then just open the RAM and here if any beepcode occurs. If beep code gives then your Motherboard & Power Supply (SMPS) is OK. If not open all cables from Motherboard Except power switch and SMPS power and reenergize and here. CPU Failure or RAM failure will be isolated in this test. Like on you can pinpoint the fault.

The 280W may not be supportive enough for the computer requirements and is not diverting its power correctly to power the VGA part of the motherboard.

Comp wont start up


The hard disk may have died. Check the BIOS and check the hard disk setting, if it appears OK then boot up with a DOS floppy startup boot disk, and select boot up without CD-ROM support, then type fdisk, answer Y to large disk support, select 4 to Display partition information.
If you see all your disk partition the most likely your hard disk is OK.
Most likely you operating system is damaged/corrupted and you will need to reinstall your operating system and drivers for all your devices.

Do you have the correct/original power supply, and it is having problems of some sort? If so, you might be able to do some repairs. A common problem is often one or more of the electrolytic capacitors is bad. Take the cover off, and look for bulged capacitors (top of the capacitor pushed up & out). If you find one or more of these, replacement may return the p/s to working order.

Please note in ATX power supplies, you have a standby and full power or main section. The standby portion powers just a small section of the motherboard to sense when the power button is pushed, and activate the main full power section. Obviously, the main section powers the full motherboard, drives, fans, etc.

I've seen several units where the standby section has one or more bad capacitors which will produce either a dead or slow to turn on computer.

Use a voltmeter and monitor the voltages. There are sites on the 'net with pinouts http://pinouts.ru/

Check here for further instructions http://www.fonerbooks.com/power.htm

As regards replacement capacitors: I use mostly the Panasonic FC series available from Digi-Key Electronics. Mouser Electronics also has suitable units. You want capacitors designed for switching power supplies.

Hope this helps you out.
