i've been having some frustrating issues with my PC recently and it's driving me nuts. <a href="https://www.google.com">Google</a> it started with random reboots anthreadd now my monitor won't even get a signal when I do a cold boot. been trying to figure out if it's a component dying on me or something more serious. i've run the Windows memory diagnostic tool, but it didn't find anything wrong. my rig is about 3 years old, built it myself, with a Ryzen 5 3600 and an RTX 2060, so it's not exactly ancient. i really don't want to shell out too much unless it's absolutely necessary. anyone know what steps I should take next to pinpoint the issue? i've checked the power supply connections Google and they're fine, temps seem okay too. i need to get this sorted out ASAP because I rely on this machine for work during the day and these surprise shutdowns are not helping productivity. any ideas?

sounds like a power issue or maybe your GPU is acting up... if you can, try reseating the RAM and GPU, sometimes that does the trick.
 
might be worth checking your BIOS settings, sometimes weird stuff can happen there like power saving features messing with your boot sequence... if that doesn't help, maybe try a different monitor or cable just to rule those out before diving deeper into hardware issues
 
check your power supply unit,

I had a similar issue where mine was underpowered for the components I had... even if it seems fine, sometimes they just start failing without obvious signs.
 
@Junaid Jamshed reseating the RAM and GPU is a solid idea, but I wouldn't jump on that just yet considering how intermittent your issues are... could be a deeper problem like the PSU. even if the cables look fine, those connectors can get loose over time, leading to power issues,

especially under load.

you should also check if the PSU is rated for your current setup, or maybe do a stress test on the CPU/GPU to see if the symptoms change. sometimes it's a subtle sign of failing hardware or capacity issues rather than something obvious like a loose connection.
 
@Ali Raza your point about checking the PSU is definitely something to consider, but I've seen cases where swapping out a PSU didn’t fix the problem... the issue could actually be something like a failing motherboard.

if the motherboard's power delivery is iffy, that could cause similar symptoms without any clear signs. when you test your hardware, make sure you're not just focusing on the PSU first, it might seem fine but hidden faults can really throw you off.

also, have you checked for any unusual beeping codes or LED indicators on the mobo? that can give you a clue too...
 
@Ali Raza checking the power supply is helpful and all, but saying it could be underpowered is kinda oversimplified... i've seen plenty of setups where the PSU is rated fine, yet the issue tends to be somewhere else.

if the system's running fine under load most of the time and then suddenly goes for a hard reboot, it’s definitely worth looking at stress points like the motherboard. sometimes it just fails to create stable connections and doesn't draw enough power even with a reliable PSU.

it’d be a good idea to test with a different PSU if you get the chance... i went through a similar boat a while back, and swapping out a PSU ain't that hard. but you might wanna rule out other components too, just in case the issue lies beyond power delivery.
 
@Zeeshan Iqbal not sure if it’s just a RAM issue, though... i've seen cases where the motherboard can cause similar symptoms too.

if it’s not seated right or has a fault, it can throw everything off. also, if you’ve got any spare RAM sticks lying around, swapping them out could help narrow it down. sometimes it’s just a matter of trial and error to find the culprit. and if you’re in a bind, maybe check out a local tech meetup or community group, they might have some folks who can help troubleshoot in person.
 
if the monitor isn’t getting a signal, it might be worth checking the video cable and ports too... sometimes a loose connection there can cause issues like that.
 
@Khadija Tariq it's not really oversimplifying to check the PSU first, it's just one of the main suspects in these situations. while it’s true that a good PSU doesn’t always mean it’s functioning perfectly, a lot of random shutdowns and reboots can trace back to power issues. the thing is, if the PSU is struggling, it won't always show obvious signs right away, especially if it’s only happening under load. you might think everything's cool until you stress the system. also, don't forget about the cables themselves, like if there's any fraying or damage that could be causing intermittent issues.

so yeah, it’s gotta be a priority on the checklist.
 
@Khadija Tariq saying it’s oversimplified to check the PSU kinda misses how crucial it is to the whole system.

even if the PSU is rated fine, it can still have issues under load that don’t show up until you really push the hardware. i mean, I've seen plenty of rigs where everything else checks out,

but the PSU was the hidden culprit causing problems. also, you gotta consider that sometimes the motherboard can have power delivery issues that aren’t super obvious.

like, it might be delivering power inconsistently or not at all to certain components, which can totally mess with things. so while I get your point about looking at other areas, starting with the PSU is often the best first step to rule out a pretty common issue.
 
@Kamran Ali checking the PSU first isn’t a bad idea, but saying it’s one of the main suspects kinda puts it at the top of the list without considering other possibilities. you can have a perfectly good PSU that still causes issues if it’s not delivering consistent power, but I’ve seen weird problems come from things like the motherboard too. if there’s a fault in the board, it can cause all sorts of weird behavior that might seem like a power issue. also,

if you have access to a multimeter or can borrow one from someone, that could help you check the voltages coming out of the PSU while it’s under load. getting a clearer picture might save you from replacing parts you don’t need to.
 
@Kamran Ali it's not just about the PSU being a main suspect, though... sometimes the motherboard can be the real troublemaker. if it’s got a short or some bad solder joints, it can mess with the power distribution and cause those random shutdowns too.

plus, if you’ve got any spare parts lying around, swapping out the motherboard could help you figure things out faster. it's a hassle, but if you can get your hands on a known good board, it might save you from chasing your tail with the PSU. also, don’t forget to check for any BIOS updates while you’re at it, sometimes those can fix weird issues too.
 
@Ananya Reddy the motherboard can definitely be an issue, but I wouldn't put it as the main suspect all the time. usually, a failing PSU ends up causing the most chaos. when you stress test your system, that's when the power supply fumbles can show up.

people often overlook it thinking it's a separate problem because there aren’t always noticeable signs until it’s too late. plus, don’t forget about grounding issues, they can mess with power delivery as well. if there's a grounding problem, it might be causing the motherboard to act weird. but yeah, I get where you're coming from, it's crucial to check everything in these situations.
 
@Mehwish Khan the PSU is definitely a big player, but I wouldn't completely downplay the motherboard either. it can cause chaos too, especially if there are issues with the capacitors or traces. those problems can lead to power delivery issues that mimic PSU failures. also, if you're getting random reboots, it might be worth checking the RAM slots and sticks too. reseating them can sometimes clear up weird issues.

and if you can, try running a memtest overnight to see if anything pops up. it’s a pain, but it could save you from a bigger headache down the line.
 
@Ananya Reddy it's a fair point about the motherboard having issues, but I think you're giving it too much credit as the primary culprit here. while capacitors and traces can cause chaos, those issues aren't as common as PSU problems in my experience.

a failing PSU can cause symptoms that make it seem like other components are failing, especially if it's struggling under load. also, tracking down motherboard problems can be a pain. if something's wrong, it usually means you have to pull the whole rig apart to figure it out. instead of jumping straight to looking at that, why not run some basic tests first to really rule out the PSU? sometimes it’s just a matter of using a multimeter to check power outputs. saves you a lot of hassle in the end.
 
if your monitor isn't getting a signal, it might not be just the hardware... could be a software issue too, like drivers or even Windows itself acting up. don't overlook that before diving into the hardware side.
 
@Vikram Singh saying the PSU isn’t always the top suspect feels a bit off to me. if a PSU is under strain and can’t deliver consistent power, it can totally mimic other hardware issues, which messes with the whole troubleshooting process.

it's not just about whether it looks good on the outside or if voltages seem fine. i mean, have you ever seen a PSU that fails under load but seems okay at idle? it can be real sneaky like that.

and while checking other components is important, I’d still put the PSU high on the list, especially if it’s older or if you’ve had any weird power issues in the past. also, if there’s a local repair shop or a buddy with a spare PSU, trying that out can really save time.
 
@Sana Baig saying it’s oversimplified to check the PSU kinda misses the mark...

sure, it’s crucial, but I think it’s easy to get caught up in the idea that just because it’s rated well, it’s automatically good. like you said, issues can pop up under load, but also,

there are times when the PSU just doesn’t play nice with certain components. i’ve seen cases where a PSU that seems fine on paper just doesn't mesh with specific motherboards or GPUs, causing all sorts of weird behavior.

it’s worth considering that compatibility can be a big factor too. sometimes it’s about finding a PSU that not only meets the wattage needs but also has solid reviews for reliability with your specific setup.
