815269 2009-09-30 21:27:00 Speedfan isnt known for its' accuracy with voltages. Lots of hits with Google on that subject.

It would be easy to do a memory test with memtest. That would at least eliminate the ram as cause.

For diagnostic purposes, I would run ccleaner (www.filehippo.com) and on the tools>startup tab, I would disable everything there and reboot.

815270 2009-10-01 03:20:00 Maxtron 420W PSU?

Probably some cheap junk....

But it could be overclocking/heat problem...

815271 2009-10-05 21:51:00 One more question - if you have an ATX Case with 420W PSU ,and you wanna get a 600W PSU, do you have to change your case or something? secureprivacy (11611)
815272 2009-10-06 01:13:00 Only if the new 600 Watt PSU was of a physical size that was too big to fit in the case...

But make sure you get a good brand PSU, please

Have you checked CPU temperatures though? and tried taking the OC off?

815273 2009-10-06 04:54:00 CPU always under 30C without overclock (11C this morning!) - took ovrclock off,problem still there, but less frequent.

Can you recommend me good PSUs? Are Hyena and Antec PSUs very good?

815274 2009-10-06 06:44:00 Hyena are considered one of the worst and Antec one of the best.

Personally I like Enermax PSUs but there are many others such as Corsair which are very good.

I don't know what anyone else thinks but I'm not sure if there's enough information yet to point the finger at any specific part - but an overloaded or overheating PSU will shut itself off and require a power cycle to reset it, which does fit your fault description.

815275 2009-10-07 09:30:00 Some machines will give a report on the voltages on a page in the BIOS setup... might be another way to check whether Speedfan is giving you the right data.

Might also be worth popping open the case and looking for any capacitors that have any hint of a convexity (bulge outwards) on the shiny metal cap on their top surface.
If you're bold, subject your PSU to the same examination. I've had a really busy time with bad caps lately.

815276 2009-10-08 08:30:00 Mine was doing something similar when running win xp. I had 6 hard drives, 1 optical, 2 pci cards, 1 video card, usb gizmo's plugged in & 2 fans all running from a 400watt P/supply. I disconnected things 1 by 1 thinking the same as you & it made no difference, the computer packed a sad alltogether & wouldn't boot, so I stuck win 7 on it, loaded it all up with the hardware again minus 1 hard drive & it's all good. It's been going for a few months now & hasn't played up yet. So with my powers of deduction I blamed XP Phil B (648)
