Question

tried booting off of xp cd but dosnt work

Answer 1

you shouldnt leave it on for 7 days. restart it every day

Answer 2

need a bit more detail on problem.
How Old is your system? Is it a P1, PII, PIII or PIV or later system? What changes have you made to it?

Just off the cuff, sounds like it could be a motherboard problem with capacitors that are going bad.

I had a pc problem similar where it would start up then after a while, die. I could start it back up and once in a while it would stay on for up to a day but then die. Other times, it just wouldn't boot at all.

Capacitors normally have a lifespan of 5-7 years depending upon usage.

It could be the Processor is getting too warm - try downloading a free program called SpeedFan - different systems have different max heat rating but it shouldn't read anything over 50.

As suggested in previous answers, use a can of pressurized air and blow out the fans and heat sinks. That could make a great difference in your pc performance. Don't turn the can upside down as it will blow freezing liquid on the circuits. All you want is the air!

Also, leaving a PC on will cause no more damage to a PC than turning it on and off every day. With the exception of the cost of electricity. My PC that I use for work has been running non-stop for the past 3 years with the exception of power outages, cleanings, etc. and it is still working fine.

Is the Power Supply, CPU and Case Exhaust fas running when you push the On Button?
Can you hear your Hard Drive Spin and start crackling when you push the On Button?

Answer 3

Try cleaning it. Open up the case and clean the dust out with a vacuum cleaner. A can of compressed air is good - but be sure to blow dust out - not in. it sounds like something overheating - probably the CPU - but it seems weird it takes 2 days to cool down. A can of that stuff that freezes - can help find the problem. be careful near the mains switch and power supply if you're working with it switched on - and earth yourself before touching anything sensitive. If you have the XP CD try booting off that too.

Answer 4

this sounds to me like a overheating problem karen
the reason i say this is because of the time frame you give until it starts to freeze,then after 2 days its ok(after its cooled down)
the main component in a p.c that will cause a freeze if it gets too hot is the processor
thats why modern cpu fans are massive bleeders,normally around 3 inches wide,as cpus such as pentium 2,3,4 and amd64 cpu,s get very hot if not correctly cooled
windows will automatically either shut down or freeze when the cpu overheats,its a kind of saftey feature
sp what i am going to recommend is acomplete m.o.t of your p.c,the entire p.c needs to be cleaned,paying extra attention to the c.p.u fan and any other fans such as chassis fans and graphic card fans,then clean the motherboard of dust,as this could cause a short which may freeze the p.c
also check the correct fitting of all components,including memory modules,graphic cards and ide or sata connections,check that the ide cables are not faulty or defective,i had a case were my p.c was freezing,and it was a damaged ide cable from my dvd rom,a simple £2-50 replacement and the problem was sorted
after the inside of the p.c is finished,then check the operating system,do a virus scan,followed by a spyware scan ,this will eliminate any viruses or spyware that may be causing the problem
finally another reason for this type of problem is power failure,your p.s.u could be on its way out,again i fixed a p.c which was suffering from intermitent crashes and the problem was the p.s.u
a new p.s.u isnt too expensive,normally around £20 for a 400watt model
give this all a go and if your still having problems let me know
good luck!

Answer 5

I would suggest trying: 1) Raising the ambient temperature in the room. 2) Checking the components installed online for minimum operating temperatures and replacing them with something more robust if you find an issue. 3) Trying to keep the humidity in the room to a minimum. 4) Checking for any failing components. 5) Looking at ways to insulate the PC if needed (although not too much as it will still need to dissipate a lot of heat once is has got started).

Answer 6

If you have any fans on your tower check make sure they are blowing out and not in..
Ideally have two fans one at the front and one at the back,
The fan at the front must blow in and the one at the back blows out also check the fan on the prossesor making sure theres no dust on the fins and it's not obscured by anything.
If none of that helps try leaving the side panel of the tower and when it reboot check components to see if there hot..
Good Luck with that

Answer 7

Hi. The freeze may be caused by heat. Two days? That starts to sound like a faulty power supply.

Answer 8

Hi. I'll need to know a little more so i can diagnose it properly. you can email me at [e-mail].
Question
1. Is it slow?
2. Does it not respond?
3. Does it chuck you to a Blue screen?
4. When does it freeze? Loading screen or during Windows?
Email me asap so i can get to the bottom of the problem.

Answer 9

Have you run a complete scan for malwares? Check to see if your hard drive is fragmented, and defrag if needed. Also eliminate all but essential start-up programs using msconfig.

Answer 10

*it overheating have a look at the fans clean them
