Alright guys, for the last few months my PC has been - well, glitchy. For example, sometimes it hangs at POST (although a reset usually solves this), and sometimes it doesn't load the OS. (Again, a reset resolves it and from that point on it usually behaves itself.) Once it's got past the booting stage, though, everything seems fine - no glitchiness or reboots to speak of. (Other than what Windows comes pre-packaged with, lol.)

Now, this problem first started when I was using my old Maxtor HDD along with my ASUS motherboard. I'd tested the RAM using MemTest (which checked out fine), and since moved my primary drive to a 36gb Raptor (using my Maxtor as a slave drive for file storage), and upgraded to an ABIT CrossFire mobo. This hasn't eliminated the problem, and, although intermittent, it is rather irritating.

Alarm bells started ringing, however, when I switched on this morning to be greeted by a cacophony of beeping from the BIOS. I reset the PC, it booted into Vista, however my Radeon had essentially disappeared. Vista promptly redetected and reinstalled it, and everything seems to be running smoothly again. (For now, at least.)

My thoughts would be a possible dodgy PSU, since the motherboard is relatively new (~2 months), and the RAM seems fine. Temperatures all check out too, it averages ~30c system, ~35-40c (under load) CPU and (last time I checked) ~35-40 GPU. I'm asking you fine people for advice in case anyone has had a similar problem before, what caused it, and how (if possible) they fixed it.

System Specs:

AMD Athlon 64 3700+ @ 2.2Ghz w/stock cooling. 1gb Corsair XMS ABIT AT8 Mobo HiS Radeon X800GTO 256mb PCI-E 36.6gb WD Raptor HDD 160gb Maxtor DiamondMax 10 HDD Samsung DL DVD+/-RW ThermalTake 430w PSU

Cheers.

I'm suspecting your right. You can get a psu tester for around $20, but best of all, you can just test with another PSU. You don't even have to put it IN the case, just leave it on the desk, and attach all the pertinent power units minus the opticals, just to bench test. I wouldn't overlook your wires, SATA, hdd, ribbons etc. I had a similar experience setting up my wifes rig, I had inadvertantly cut one of the lines while clipping some zip ties up and was not powering up properly. Soldered it clean and painted some liquid electronic tape over the exposed areas. I'm willing to bet it's something real cheap and easy fix. My guess, bad SATA or a wire is not properly seated in a molex, or bad wire somewhere.

Yeah, I'm going to see if I can swag a spare PSU from a mate in the next few days so I can do some tests. Although your point about the SATA connector is something I hadn't considered - the back end of my GPU cooler (it's a tad huge, lol) sits right over the SATA ports on the mobo, and as a result I can only use the third and fourth connectors, and even then it's a tight squeeze. I'll open it up a bit later and have a look and see if one has come loose, I have to replace my optical drive anyway. (Just got a new burner back after an RMA.)
