It is in fact an HP Pavilion but running Windows Vista. I'll add that even a problematic firmware or driver can cause that exact same symptom so it could be anything. If you have a good working spare drop it in, but I'd not conclusively say it's failed and agree with Wrapper. As well as disabling the automatic restart itself, as it can aid in troubleshooting (google for instructions). You might want check your application and system event logs for errors around the times of the problem. Calabrese Windows automatically restarts instead of displaying a bluescreen now if it can. Yes they're 3 times the price of the no names, but factor in how much it would be to replace your motherboard or other parts, if a cheap PSU takes them out. You'd do well to read reviews of PSUs on jonnyguru before investing in it.ĮVGA G2 series of supplies give a good 'bang for buck' in the PC PSU world. You'll save your PC components from a hard life, and have decent protection in case of a fault. Do yourself a favour, and invest in a good one. Also many cheaper PSUs can be the cause of random crashes due to unstable, high ripple, power rails. Many people skimp on computer PSUs, forgetting its the heart of the system, till one fails catastrophically, and takes out their expensive CPU's, GPUs, SSDs and HDDs with it. I second the motion to just replace it, with a good quality PSU. It seems to me this is a matter of a component in my power supply on its way to total failure.
If I can save myself the money of buying a new power supply off eBay that may or may not work properly by replacing simple components I would like to.

The +5v has a good resistance on the motherboard itself. I have checked this resistance with my leads in both directions and tested the power supply when disconnected from the computer completely. My questions are: Should the resistance be that low?Īnd without a schematic is there any way to trace the +5v back without using my meter in continuity mode and trying to follow traces to get to the issue? The supply itself is a mess of silastic and very difficult to see on the top. The computer works but randomly restarts with no blue screen message. To the best of my knowledge the resistance shouldn't be that low.ĮGD IT EQUIPMENT DESCRIPTION YOU ARE BUYING A NEW x 1 HP 300w 24 Pin ATX Power Bestec ATX 0300 D 5 WC REV:B585008-001 EGD30 SHIPPING NO COLLECTIONSDELIVERED VIA.
