I noticed my father's XPS 8300 running a lot when it should be in sleep mode. I suspected malware keeping it awake. I ran a scan with ESET Smart Security 8 and found nothing. I ran a scan with Malwarebytes anti-malware and it found some potentially unwanted programs. I deleted them from the quarantine. This morning my father could not get the computer to wake up. The power light flashes amber and it makes a revving noise, but does not continue to boot up.

I tried holding the power button down to make it shut off completely. I tried unplugging it for a few minutes.

It won't get to BIOS for me to try anything. It is running Windows 7 Home Premium. Windows keeps trying to force me to install windows 10, but I am not ready to. Maybe it tried again. I have read many threads on the 8300 problems. I am thinking of removing the CMOS battery for awhile to reset BIOS settings. What do you think?

Here is some system data. The main change is I added a USB 3.0 card. From the: If the power light is blinking amber — The computer has detected an error during POST. There might be a problem with the system board or the power supply. More likely to be a power supply issue than motherboard.

Does the power supply have a green LED on rear of PC? Is the LED on the motherboard on as long as PC is connected to a working outlet, even if PC is off? You can try the 'paperclip' test: • Power off, unplug • Press/hold power button for ~15 sec • Disconnect power supply cable from motherboard.

• Insert bent paperclip into hole for green wire in the connector and put other end into hole for black • Plug PC in and see if fans and HDD start spinning • If not, you may need to replace the PSU If you need more details, google for 'paperclip test' and you'll find youtube vids and other tutorials. Note: This is not a definitive test and installing a known working PSU is the most accurate way to answer the question. BTW: If you replaced the motherboard battery, you've reset BIOS to the defaults and some of those settings may not be right for this system, eg if you have 2 hard drives set up for RAID. But even if settings aren't correct, you still should be able to turn the PC on and get into BIOS setup. Sorry to hear the new PSU didn't resolve the problem.

Please recap exactly what happens when you try to boot with the new PSU installed. Is the motherboard LED on, 24/7, as long as PC is connected to a working outlet? If not, failed motherboard (or bum PSU). Any error messages on screen or beeps from the tower? Does the monitor go right into 'stand-by mode'? Even if you have a motherboard that wasn't updated, it should still boot. The boot drive should be connected to SATA0 on the motherboard and that port wasn't affected by the Sandy Bridge mess.

You can try stripping it down to bare essentials by removing all PCI cards except video, removing all RAM modules except the one in slot 1 (but reseat that one in its slot), disconnecting all drives except boot hard drive. Then remove motherboard battery and press/hold power button for ~30 sec.

If it still won't boot, remove the last remaining RAM module and do the 'battery thing' again. If you don't hear any beeps without any RAM installed, the motherboard failed. If you hear beeps with no RAM, the board may still have some life in it. So now reinstall one RAM module (use a different one) and remove video card. Do the battery thing again and see if it boots with monitor connected to one of the on-board video ports. And you stripped it down by removing / disconnecting everything I mentioned?

BTW: If you're using a power strip, surge protector or uninterruptable power supply, remove those and connect the PC directly to a working wall outlet. You should have gotten 2 beeps for 'No RAM detected'. So assumingthe replacement PSU is ok, then it's sounding like a motherboard failure.

You can find the motherboard,, eBay, etc. You want a board with the revision B 3 chipset that fixed the Sandy Bridge issue. And always ask if new, used, refurbished and about warranty. Only you can decide if and how much money to spend trying to fix this system, keeping in mind that I can't guarantee a new motherboard will fix the problem, vs putting that money toward a new PC. I realize this one isn't that old but you should think about it. Post back and let us know what happens if you decide to replace the board.
