Hey everyone.
I built a pc yesterday for someone and went to power it on, and when I did so it would boot for various periods of time and then restart. It'll restart 3, maybe 4 times then simply not respond to power at all. I have to pull the power cable for 3-5 seconds for it to fire back up.
First I monitored the CPU temp in BIOS and verified that it's not overheating. I then dropped the memory to one stick and tried diff sticks in diff slots. I decided to gut the case and bench test. Thought about the reset cable shorting out so I didn't connect any of the front panel cables and just powered it on by shorting with a screwdriver. With just one stick RAM, vid card, cpu, and psu the problem continued. tried a diff vid card with same results. I do not have another compatible psu (unfortunately) to test and i understand there may not be much I can determine w/out getting one, but does anyone have possible suggestions of what to try next or has anyone experienced this before and can help? Oh! I also performed a "load test" on the PSU by just having one case fan hooked up and shorting the green/black wires with a paper clip. Seemed to run fine but this really just tells me that the PSU can handle a small load and not an entire PC.
q8300 2.5ghz Intel Quad
Giga-Byte EP45-UD3P P45 motherboard
radeon 4670 1gb vid card
Kingston 4x2gb RAM
Corsair 550VX PSU
If any other info is needed just let me know. Thanks in advance for any help!
