Windows 7: Desktop bricked after using RT Seven Lite, won't boot into BIOS

Before connecting the PSU, do just connect the basic first.

MB, & 1 HDD with Windows OS, for start, as 300W is more than enough.

PSU connectors to MB is unique, should not mix, and do ensure it is slot in tight.
You are testing the MB and HDD and system.

Other HDD, optical drive, etc, best to avoid for the time being.
Otherwise you would not know which item is the cause of the failure.


Edit: Go to BIOS first, as to ensure it can see HDD and other setting. And do F10 to confirm the setting as you had being doing the jumper.

If your computer is the one in your specs you should be safe to try that 300W power supply just to see if it will boot. I wouldn't try overclocking your processor or heavy gaming though lol.

Just a reminder to remember to hook up the CPU power. It's usually a 4 or 8 pin connector beside the CPU. The corresponding wires on the PSU are usually labelled "P4" or "P5" with P4 being the most common. Make sure that particular one gets connected or the PC won't boot.

Okay, I finally installed the PSU, and the good news is you were right - the PSU was definitely the problem. I managed to get the computer up and running with the borrowed PSU, though I did have a worrying - though small - problem with Windows 7; namely, the timedate.cpl file had its file association reset, and restoring the computer to different restore points didn't fix it, so I had to manually set that file to open with the Control Panel. It's primarily worrying because it makes me question what else might have come undone. I considered a Repair Install, but don't really think it's worth the hassle right now, so instead I'm just running a virus/malware check. Even more worrying, the whining noise is persisting, coming from the secondary hard-drive, and the rest of the computer seems to be making more noise than usual. Odd.

Anyway, it looks like my main worry right now should be shopping for a new PSU. Can either of you recommend a cheap one? One of the first ones I came across was this:

Ace Black 120mm Fan 550W Fully Wired Efficient Power Supply - Ebuyer

I really can't afford to spend that much on it, so I'm wanting to stick within that sort of price range. Would that be sufficient for my comp? I do notice it does only have the one 12V rail.

I realize that you are on a limited budget. That being said, the last thing that you should try to economize on is your PSU. It's the heart of your system. I looked at the site you linked and was able to find a couple of better PSUs at what I would consider a modest price. Now, I know that these are at least 2 to 3 times what you were looking at in terms of price, but I can't stress it enough: Don't cheap out on your PSU.

Anyway, here are a couple of PSUs that are better choices:

EVGA 430W Fully Wired 80+ Power Supply - Ebuyer

Corsair VS Series 550 Watt VS550 Power Supply - Ebuyer

Obviously, they are higher in price than the one you linked, but given that they are pretty good brands they should be solid performers. If there is anyway that you can scrape together enough money, one of those two would be a good bet.

And I'm concerned about this whining sound from your hard disk. Does it change with disk activity?

Exactly.

I went the cheap PSU route many years ago. In the long run it will cost you much more, both in parts and in troubleshooting. Look at what you've been through the past few days with this problem. Are you ready for more phantom glitches on a regular basis due to unstable power? How about watching your whole MB go "poof" when something fries internally in the PSU? A slower CPU can be tolerated. A cheaper MB might have a few less features. A crummy PSU can and will do in the whole works.

Before getting the PSU, check the size and which side the connectors and main power connector are.

Although it is standard, it is better to check.
As some PSU have the wrong side, when i forgot to check, have to go for the exchange.
